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.
