COSMO-CZ-EPS

Popis výsledku v původním jazyce

The COSMO-CZ-EPS was formerly planned to run on IC+LBC from COSMO-SREPS. Unfortunately, the number of COSMO-SREPS members was decreased and in December 2012 it was stopped at all. The actual ensemble uses an IC+LBC from COSMO-SREPS and has 16 members. The forecasts start at 06UTC and the lead time ends at 42h of forecast. The article shows a comparison of COSMO-CZ-EPS with parent COSMO-LEPS. The verification was made on July 2012. This episode was challenging for precipitation forecasts because there was a few episodes with heavy convective precipitation and the end of July was significantly drier. Both ensembles show a small dry bias. It is possible, that the bias of COSMO-CZ-EPS can be affected also by the start of the forecasts at 0600 UTC; the tests performing the forecasts from 0000 UTC should be done. The verification results show better forecasts of COSMO-CZ-EPS than COSMO-LEPS for events with heavy precipitation. These events are of high interest and the comparison confirms tha
