The Growth of UK Viticulture

News / The Growth of UK Viticulture

Viticulture Through the Ages

Although wine has been drunk in the UK since the Iron Age, it was the Romans that first introduced winemaking to the UK, with some evidence suggesting vineyards were planted in the UK during their time here. Viticulture saw an upturn in popularity during the Norman conquest, partly due to the Medieval Warm Period, but also due to nobles and prominent landowners wanting their own wine [1].

A few hundred years later however, as the climate began to worsen (towards the Little Ice Age) and the monarchy (Henry II) gained Aquitaine through marriage, better wine was found elsewhere and vineyards dwindled. By the 18th Century, only a few estates across southern England had vineyards, albeit very small and experimental in scale [1].

This all changed during the 1900s due to climate change and globalisation. As global temperatures rose and warmth spread into higher latitudes, more of the UK became suitable for different grape varieties. Compounding this with the increased ease of importing and exporting goods, viticulture in the UK became more economically viable than ever. Both of these drivers still continue to push vineyard growth throughout the UK. In fact, hectarage has doubled since 2016, showing the fast rate at which the UK viticulture sector is growing, and as of 2024, there are now 1,097 vineyards, totalling 4,491 hectares. To help show this rapid growth, the video below shows how many new commercial vineyards were planted from 1955 onwards in the UK and Ireland (226 vineyards do not have a date of first planted, and so these were left off to avoid cluttering the map) [2].

The two main varieties grown in the UK are Chardonnay and Pinot Noir, but other less known varieties are also very common, including Pinot Gris, Meunier and Bacchus. While the main production of wines from the UK are of the sparkling variety, still wines comprise around a third of the total. Both types of wine have been gathering recognition and acclaim on the global stage, to the point that high profile Champagne producers (e.g. Taittinger) have been buying real estate in southern England [3], thus proving the UK’s position in the world of viticulture and the exciting prospects it holds for the future!

This growth of UK vineyards is not without risk however. During the bud burst season of March – May, vineyards (and specifically the buds on the vine that have burst) are at risk of the effects from frost, despite our changing and warming climate. These frosts can severely damage the crop and cripple yields, and for this year’s vintage, the clear and settled weather we have been experiencing has been producing frosts across the country. To help vineyards mitigate this frost risk, WeatherQuest are leading on a project which has secured over £300,000 in funding from both Innovate UK and the Department of Food and Rural Affairs (Defra).

Working alongside, UK Agri-Tech Centre, Plumpton College, Vinescapes, Vinewatch and WineGB, the project is called ‘Smarter Forecasting, Communication and Management of Frost Risk in Vineyards’. By creating accurate, real-time, hyper-localised, site-specific, and variety-specific frost risk forecasts, it will enable vineyards managers to make more confident, informed and targeted decisions when it comes to frost mitigation, with the added benefit of sustainability in mind. The project will therefore aid the rapidly growing sector of domestic viticulture in the UK and their resistance to frosts.

The Weakening AMOC

News / The Weakening AMOC

What is the AMOC and why is it so important?

Ocean currents are incredibly important in maintaining climate stability around the world. One of the most important of these currents is the Atlantic Meridional Overturning Circulation (AMOC), which holds a vital role in the climate of the North Atlantic. Cold waters in the Arctic sink and flow southwards along the depths of the Atlantic, where they reach the Southern Ocean. Here, the circumpolar winds act as a “pump”, upwelling this water where it then begins to travel north. As the water does so, it gradually warms, providing areas such as the Caribbean and Gulf of Mexico with warm Sea Surface Temperatures. In the final leg of its loop, the current flows northeast across the North Atlantic (via the Gulf Stream), bringing warmer waters to Western Europe, before extending back up to the Arctic. This is one of the reasons the UK has milder winters relative to other countries at the same latitude.

The AMOC is also responsible for making the Atlantic one of the largest global carbon sinks. Upwelling from the deep ocean brings nutrients which supports phytoplankton and therefore photosynthesis at the surface, storing CO2 biologically. On top of this, the upwelling water is thousands of years old and contains far less CO2 than the surface water. When in contact with the atmosphere, this water absorbs large quantities of CO2 (DeVries and Primeau, 2011). These three climatic systems cement the AMOC as one of the most important global currents in the world.

Climate change and the AMOC

Among many statistical models, it has been forecasted that under global climate change, due to melting ice and warming global ocean temperatures, the AMOC will weaken and could even collapse and shut down by the mid-to-late-century. Due to the systems described above, this would have serious consequences for oceanic carbon uptake and heat transfer for regions around the world (Hu, 2025).

To further our understanding of the weakening AMOC, a joint Met Office and University of Exeter study by J. A. Baker et al. (2025) compared 34 CMIP6 climate models focusing on extreme greenhouse gas and North Atlantic freshwater forcing scenarios and their impacts on the AMOC. They found that across all models, the AMOC does not collapse, but levels off at differing weakened states depending on the model, and is sustained by the upwelling wind-driven “pump” of the Southern Ocean. Although this “pump” is modelled to strengthen in the chosen climate forcings, a Pacific Meridional Overturning Circulation (PMOC) begins to develop in the Indo-Pacific, taking away some of the volume of waters in the AMOC therefore weakening the overall circulation.

J. A. Baker et al. (2025) suggest the system is balanced by the water entering the circulation and the water leaving; in order for the AMOC to collapse, strong upwelling would need to be provided by another system, hence the development of the PMOC. The strengths of the PMOC from the models do not reach significant levels to completely compensate for a shut off the AMOC, hence only weakening it (Hu, 2025). Therefore, although an AMOC collapse this century is not likely, its weakening is dependent on the development of a PMOC, and how strong this circulation becomes.

Despite the findings that the AMOC may not collapse this century, even just a 50% weakening of the AMOC will still have massive global impacts due to the reduction in heat transport, nutrient circulation and carbon uptake of the ocean. Therefore, this modelled weakening must still be viewed as of high concern and the continued studying of the AMOC’s relationship to climate change is vital.

Moray West Milestone

News / Moray West Milestone

Last Turbine Installed!

We are incredibly proud to hear from Ocean Winds that the last (60th) turbine has been installed at the Moray West Wind Farm in the Moray Firth, Scotland!

WeatherQuest worked with Ocean Winds during the construction phase of the Moray East Wind Farm, up until September 2021 when the final turbine was installed. Through this service, we were kindly invited back to support the construction of their next project in the Moray Firth, Moray West.

The construction of Moray West began in 2022, with the project aim of producing its first power in 2024 and becoming fully operational in 2025. Since 2022, WeatherQuest has been providing Ocean Winds with our WindQuest service, aiding in construction and other marine operations. With the help of this service, Ocean Winds managed to limit weather-caused down time, staying on track with their aims; the wind farm produced its first power in July 2024 after nearly a third of the 60 turbines were installed. Fast forward to the end of the year, and by November 2024, all 60 of the turbines were installed. Once fully operational the wind farm will provide power equivalent to the needs of 1.33 million homes, saving 1.1 million tonnes of CO2 per year.

WeatherQuest have a strong working relationship with Ocean Winds and are happy to report that we will continue to supply Moray West with the WindQuest service into its Operations and Maintenance phase.

Well done to the team at Ocean Winds and everyone who worked on the Moray West wind farm! We look forward to continue working with you into the future!

Relaunching the RMetS East Anglia Centre

News / The RMetS East Anglia Centre

The Royal Meteorological Society East Anglia Local Centre is making a comeback! Two of our WeatherQuest forecasters (James Lester and Bernadette McCaffrey) are relaunching the Royal Meteorological Society’s (RMetS) East Anglia Centre this autumn. The Centre will meet 6 times a year, with topics aimed to meet a broad range of subjects from across meteorology and climate. Each meeting will be free of charge, and available to members and non-members. Professional meteorologists (working or retired), under- and postgraduate students, or members of the public with an interest in all things meteorology and climate, all are welcome!

The first talk, hosted at the University of East Anglia’s Julian Study Centre on the 7th of October, is from our very own Chief Communication Officer – Chris Bell. The talk will focus on Storm Chasing in the American Great Plains, and what makes them so unique for producing such large storms and tornadoes. Despite residing here in the UK, Chris grew up in Texas and has made many a trip back to the USA to chase storms through the infamous “Tornado Alley” of the Great Plains. Chris will talk about his own experience in storm chasing, where, why and how people do it, and then delve into the science behind the storms, explaining how they are produced, and what time of year these large supercells/tornadoes normally occur. With his experience in forecasting, meteorology and storm chasing, it is looking to be a fascinating talk!

El Niño Southern Oscillation and Winter: How does it impact us?

News / ENSO and Winter: How does it impact us?

The El Niño Southern Oscillation (ENSO) is one of the world’s most dominant climatological oscillations and is our planet’s single largest source of natural year-to-year variability. Caused by sea surface temperatures in the equatorial Pacific, warmer temperatures lead to an El Niño, and cooler temperatures to a La Niña. Over the last year, the world has been gripped by an El Niño, contributing to the record-breaking high global sea surface and air temperatures, precipitation extremes (high or low depending on location) and a rise in global number of wildfires (NOAA, 2024). However, as we close out Summer, ENSO has returned to neutral and is very likely to swing into its other extreme phase, a La Niña, as we head into Autumn. Having similar far-reaching impacts across the globe, how does this oscillation of sea surface temperatures over the Pacific impact the UK, and what could this mean for our weather over the coming autumn and winter?

Due to its proximity, ENSO has strong influences on surface pressure over the Northern Pacific, which in turn, impacts the weather over the USA. This is initially conveyed by the Pacific Jet stream, and during most winters with a La Niña, high-pressure builds in the Northern Pacific, often bringing warmer, drier weather to the southern States and Mexico, and cooler, stormier weather to the northern USA and into Canada. This then intensifies the North Atlantic Jet Stream, leading to more low-pressure systems (storms) being present in the North Atlantic.

This low-pressure anomaly in the North Atlantic is a sign of another climatic oscillation known as the North Atlantic Oscillation (NAO). Calculated by the difference in surface pressure from the Azores (high) to Iceland (low), a positive NAO occurs when this difference is greater than normal, which is common for La Niña winters. A positive NAO means westerly winds are normally stronger, leading to fiercer more frequent storms that track across northwestern Europe. This means that whilst milder and wetter air from the Atlantic keeps temperatures in the UK from dropping too low, precipitation (rain or snow) is more localised (Met Office, 2024) and is heavily influenced by the position of the Jet Stream.

In our previous post, we spoke about how important the Jet Stream is in controlling how much rain we get during the summer months. Well, the same applies to all seasons, with a northerly shifted Jet Stream normally bringing warmer and more settled weather to areas south of it and vice versa. During most La Niña autumns and winters, alongside a positive NAO, the Jet Stream progressively increases in strength, meaning it heads towards a zonal (straight) flow, as opposed to meridional (meandering) flow by late winter. Because there is less of this meandering, the Jet Stream can regularly split the UK, leading to drier conditions across Wales and central and southern England, and wetter conditions for the northern England and across Scotland.

The ability for the ENSO to impact our weather, despite being half a world away (almost literally) places it in a group of weather patterns called teleconnections. Teleconnections all share the ability to impact weather systems far away from their source, and as mentioned above, they are normally interlinked with one another, perpetually changing weather patterns around the world. If you would like to read more about these Teleconnections and their impacts worldwide, have a read of this fantastic article from NOAA.

July and The Jet Stream

News / July and The Jet Stream

A tale of two Julys

Being the height of summer, July is normally one of the driest and warmest months of the year. In the East of England, it normally yields around 200 hours of sunshine, average temperatures in the low twenties and total rainfall values of 45-50 mm. However, the British summer is known for being extremely changeable, with some days having blue skies and sunshine and temperatures in the high twenties, and others having rain and temperatures in the mid-teens. One of the main drivers for this changeable weather is the Jet Stream. When located to the north of the UK, it often provides warm and dry settled weather from the continent, dominated by high-pressure systems. The opposite occurs when the jet stream is located either in line or to the south of the UK, bringing cooler temperatures from the maritime region, and lots of low-pressure systems (and therefore rain) from the Atlantic.

For the beginning of this summer the jet stream has been consistently stuck either over or south of the UK, providing the unseasonably cold temperatures and higher amounts of rainfall most of us have seen. It therefore goes without saying that this July has been wetter than average so far. In fact, when totalling rainfall values for the 1st-22nd, some areas are already matching or even doubling that of the average monthly totals (seen on the 2024 rainfall maps below). This is especially the case for some areas of West London, Hertfordshire and Essex, with station values reaching between ~87-100 mms; Ealing, West London, has had more than 4 times the average rainfall for July in just the first two thirds of the month. Due to the Jet Stream’s position, many storms and convective events have blown over the UK and looking at both maps, it seems that the convective storm tracks travelled consistently over the same area, leading to these incredibly high totals.

There was a change during the 18th-21st, where the jet stream to the west of the UK sank further south, before heading north again above the UK. This led to southerly winds, bringing with them hot continental temperatures and sunshine, with the warmest temperature reaching 31.9oC on the 19th at St James’s Park in London. This only lasted around three days however, when on Sunday 21st a weather front moved over the UK, reverting the jet stream to the pattern we have had for most of the summer so far, with it located just to the south of us and providing westerly winds and unsettled weather. Unfortunately, with no sign of this changing as we head into the latter stages of the month, wetter weather and cooler temperatures will seemingly close out July 2024, with August showing the first sign of more settled weather.

Only two years ago, in July 2022, it was an entirely different story. With a few heatwaves throughout June and rainfall values below average, the beginning of July started in a rainfall deficit. From the 1st to the 5th, it was cooler than average, but on the 6th of July, temperatures rose to ~2oC above average, and by the 10th many areas exceeded 30oC. This was caused by the jet stream over the Atlantic, which had a sharp southern dip over the ocean south of Greenland, leading it to head north above the UK. This kept the UK in a warm and settled region of continental air, with a high-pressure system that slowly moved across the UK, dominating the weather for a couple of weeks. Temperatures kept rising, with little to no rainfall across much of the UK, ultimately leading to the unprecedented temperatures seen on the 18th and 19th (40.3oC recorded at Coningsby).

Despite being the same time of year as the 2024 example, you can see on the 2022 rainfall and anomaly maps above that many areas didn’t even reach 20 mm of rainfall (one fifth of the average monthly total) across the 1st-22nd July period and some areas of Essex, East London and the South received less than 5% of the monthly average. This led to widespread hosepipe bans, as water consumption skyrocketed due to the heat, whilst reservoirs and water resources dropped to incredibly low levels. There was also a record number of fires across the UK, and the London Fire Brigade had its busiest day since World War Two. After this period, the jet stream gradually shifted eastward, bringing average temperatures acorss the UK and slightly more unsettled weather towards the end of July and into August 2022.

These examples show just how changeable and different each year can be, bringing their own individual challenges. This changeability will increase into the future, as our climate continues to change. With global temperatures rising, the Jet Stream will have more energy, amplifying the frequency of its meridional flow (sinusoidal wave type pattern) state, increasing the chances of the jet stream being either north or south of the UK, and extreme events such as those mentioned will become more common. It is therefore incredibly important to improve the climate resilience of the UK, and WeatherQuest will continue to provide support for all our clients’ sectors going forward.

Off to the EGU General Assembly!

News / The EGU General Assembly

Dan Smith, Research Meteorologist, taking part in EGU General Assembly

Later this April one of our Research Meteorologists, Dr Dan Smith, will be heading to Vienna, Austria, to take part in the European Geosciences Union (EGU) General Assembly conference. The EGU is one of Europe’s leading organisations for Earth, planetary and space science research, and has over 19,000 members from across the continent. Publishing a wide range of journals and organising meetings, education sessions and outreach activities, they aim to advance fundamental research that addresses key socioenvironmental challenges.

Each year they hold a General Assembly, a large week-long conference which encourages members and non-members to take part in the different programme groups available. There are main disciplinary sessions which cover topics decided by each different scientific division, transdisciplinary lectures, debates, short courses as well as education and outreach workshops all on different days throughout the week. Two main subjects, Ocean, and Atmospheric Sciences are of interest to Dan who splits his time being a Research Meteorologist with WeatherQuest and being a Researcher at the University of East Anglia (UEA). Some of the sessions in these subjects include:

  • Numerical Weather Prediction, Data Assimilation and Ensemble Forecasting
  • From mesoscale Convection to Convective-Scale Predictions: Advances in Process Modelling, Observations, Data Assimilation and Machine Learning
  • Forecasting the Weather
  • Subseasonal-to-Seasonal Prediction, Processes and Applications

UEA Meteorology Field Course

News / UEA Meteorology Field Course

UEA students head off to the Lake District!

WeatherQuest has always had very strong links to the University of East Anglia and the School of Environmental Sciences (Env). Not only are we located on campus, many of our past and present employees are Env graduates and some are current members of the faculty, a lecturer and researcher. One such faculty member is our very own Chris Bell (CCO), who leads a module in Applied Meteorology for second year students. As part of the module, every year in mid-Spring Chris and the enrolled students embark on a week-long field course to the Lake District, with the main focus being the micro- and macro-meteorology of the area and Cumbria respectively.

At the beginning of the week, the students record what the computer forecasts are for the synoptic situation over Cumbria for the week, taking note of any changes and the general weather for each day (max and min temps and wind speeds etc). They then erect a weather mast in a location carefully chosen for its interesting micro-meteorology (e.g. downwind of a hill). This mast has an array of meteorological equipment attached, including solarimeters, wind vanes, anemometers and thermometers, with their measurements all being logged and recorded.

Throughout the rest of the week the students complete different meteorological activities, ranging from manual weather data collection (using hygrometers and anemometers), cloud observation exercises, launching a weather balloon, drone flying and met office station or other site visits. This year, it is planned that the site visit will be a walking tour of Keswick with the Environment Agency, talking about flooding and its impacts in the area. As the lake district is one of the wettest areas in the UK, flooding is a major issue in the national park and those who live in it. At the end of each day, the students then take part in a weather briefing, whereby they look at the current synoptic situation, forecast models and any weather warnings to create a presentation that they present to the rest of the cohort.

At the end of the week, the students collate the synoptic data from the week along with their logged weather mast micro-meteorology data in preparation for their assessments following the trip. Then on the final evening before heading home the next day, they take a well needed trip to the local pub, rounding the whole week off.

When home, the students then spend time completing their assessment. The first part involves comparing how well the forecasts at the beginning of the week matched the synoptic change experienced. They can then use this information to help with the second part, exploring how the micro-meteorology changed throughout the same period. They do this by completing complex calculations from the weather mast measurements, finding variables such as turbulence, sensible and latent heat flux and net radiation. They then relate this micro-meteorology to the synoptic changes (e.g. a cold front pushed through the lake district, causing the temperatures to drop along with a reduction in solar radiation).

Not only is this trip incredibly fun and informative for the students, but it also does help prepare them for a job in the world of occupational meteorology, which is very beneficial. Chris is looking forward to this year’s trip, with his fingers crossed for some interesting weather to occur!
