Description

RAVAKE is a probabilistic precipitation prediction system that applies 51 extrapolative nowcast ensemble members from the Finnish weather radar network as well as 51 PEPS members from the HIRLAM/Harmonie NWP system and 51 EPS members from the ECMWF IFS system. The main output products from the RAVAKE system consist of accurate local forecasts (resolution 1 km) of the best estimate rainfall and exceedance probabilities of rainfall class threshold in a continuous time range from 15 minutes to 5 days. Seamless continuity is achieved by blending the three sets of ensembles in the time domain.
