<![CDATA[What parameter is chosen for lightning forecast]]>Hello!

Several parameters can be chosen in order to try to model the risk of lightning.

Which has been chosen, when I for instance look at lightning risk from the IFS/ECMWF model?

Is it the K-index? Vertically intergraded graupel? Or something else?

The lightning parametrization (by ECMWF) uses a lot of parameters:
Convective hydrometeor amounts,
convective available potential energy (CAPE)
convective cloud base height etc
Also, is calibrated to match the annual mean flash densities from satellite climatology.
