Název v původním jazyce

A radar-based verification of precipitation forecast for local convective storms

Popis výsledku v původním jazyce

An attempt is made to evaluate the forecasting capability of a high-resolution numerical weather prediction model by means of area-related QPF verification. The results concern two local convective events, which occurred in the Czech Republic and causedlocal flash floods. The LM COSMO model adapted to the horizontal resolution of 2.8 km was used and the 18 h forecast of convective precipitation was verified by using radar rainfall totals adjusted to the measured rain gauge data. The grid point-relatedroot mean square error value was calculated over a square around the grid point under the assumption that rainfall values were randomly distributed within the square. The model was integrated with initial conditions shifted by 0.5° distances. The four verifications, corresponding to the shifts in the four directions, show differences in the resulting QPF, which depend on the size of verification area and on the direction of the shift.
