The movie shows a visualization of the high resolution regional weather model (COSMO-1) - currently being developed by MeteoSwiss - with simulated cloud coverage over a mosaic of satellite images.
The visualization begins 19 June 2013 and runs for several days (as indicated). The first day of the simulation was an extremely warm day over Switzerland with hardly any thunderstorms and a strong southerly flow (Foehn). On the second day, the southerly flow persists and a perturbation passes over Switzerland with associated precipitation. On the third day, the flow gains a westerly component with a low pressure system over the Northern Sea. As a high pressure ridge passes over Switzerland, clouds clear away temporarily over midday.
Spatial resolution is 1.1km while temporal resolution is 2 minutes.
The model is developed by the the Consortium for Small-scale Modeling (COSMO) formed by several national meteorological services (cosmo-model.org).
Foreground (model data): Cloud coverage (3 cloud layers in different saturations of white) as well as precipitation rate (blue layer).
Background: Blue Marble next generation mosaic of satellite images with 500m spatial resolution (August 2004).
