[en] An automatic daily atmospheric circulation patterns classification was built using the geopotential heights of 850 hPa level from the ECMWF (re)analysis over the period 1958-2007.
The classification is based on a similarity index between two 850hPa geopotential
maps centred on Belgium, taking into account the slope difference between both daily
geopotential surfaces as well as the absolute geopotential difference between both
surfaces. Wildfire occurrences are analysed in April and September together with
monthly frequencies and persistences of daily atmospheric circulation patterns types as well as with monthly variability of weather climate conditions.
