<![CDATA[Addition of ECMWF parameter CAPES to Windy forecast suite]]>Can I draw your attention to a weather parameter CAPES (combination of CAPE and SHEAR) available in the ECMWF dataset for determining conditions favourable for development of severe weather, namely severe thunderstorms.

https://codes.ecmwf.int/grib/param-db/228044

From ECMWF.- "High values of this parameter indicate where deep, organised convection is more likely to occur, if it is initiated.
This parameter is the product of wind shear and the square root of convective available potential energy (CAPE). The wind shear denotes bulk shear which is a vector difference of winds at two different heights in the atmosphere (925 hPa and 500 hPa). The square root of CAPE is proportional to the maximum vertical velocity in convective updraughts."

I have used this parameter as an operational meteorologist and have seen the benefits. I view this as a very useful addition to the Windy platform.

However, it can be changed in next months.

CAPES. (acronym for Cape-Shear)
