CliSAP successfully finished in 2018. Climate research continues in the Cluster of Excellence "CLICCS".

Surface pressure gradients as proxies for the wind climate

Geostrophic winds are the result of atmospheric pressure gradients that cause air movements from high to low. The stronger a gradient is, the stronger the winds are blowing to compensate this gradient. Hence the strength of the surface pressure difference between two locations can tell us about the wind strength in between.

In CliSAP-2 past surface pressure records of several different locations are digitalised and merged at Seewetteramt of DWD in order to investigate the gradients between locations. This allows for assessing the wind climate between these locations.
