Adrian works on cloud microphysics and aerosol-cloud interactions.

Current activities Adrian is a scientist working on cloud microphysics and aerosol-cloud interactions in the cloud-scale modelling group. Adrian uses the Met Office Large Eddy Model in conjunction with a 1-D framework, KiD and a parcel model, to simulate a variety of cloud regimes and investigate

guidance may be helpful: a. The meteorological conditions are listed in a specific order. In the weather section, the best visibility is given first. Any mountain wave activity would come towards the bottom, followed by turbulence information, and finally hill fog. b. Cloud information is given

Scotland. Anticyclones normally bring settled weather, however the seasons and origin of the airmass often result in differences in cloud cover. For example, whilst we associate high pressure as bringing fine sunny weather to the UK during the summer, the same high pressure can lead to extensive

Steven leads the Cloud and Aerosol research group within Observation Based Research. The group undertakes ground and airborne field experiments to improve the representation of cloud and aerosol physical processes in our models.

has the dominant weighting. The UK Atmospheric Hi-Res model is part of the Met Office flagship numerical weather prediction (NWP) model called the Unified Model. The resolution of the Nowcasting is comparable to radar data. The weather variables available include: • Cloud; • Snow; • Visibility

of surface SW fluxes in region North of Russia over first day LFRic has an immediate increase in surface shortwave at the first call to radiation before any cloud changes can have an effect Clear sky is virtually identical suggesting the problem is with the clouds (or how the clouds are represented

the criteria for issuing a change group in a TAF, and what this means in practice for the range of values that the forecast wind, visibility, cloud, and weather convey. Wind direction TAF change rule: a change of… What it means, in practice… 30 degrees or more in mean direction, the mean speed before or after

of rain, lets first understand how it forms in the first place. There has always been the same amount of water on the earth, but the amount floating around in the air as water vapour or clouds depends on how warm it is. Warmer air holds more water while colder air holds less. This is an important

Yoko works to quantify and reduce uncertainty in climate change, through understanding and improving the representation of cloud-radiative processes.
