Daily total precipitation probability above a given threshold.

Description & Technical Information

Description

The Daily total precipitation probability is a variable of ECMWF’s Integrated Forecasting System (IFS). It measures the 24-h accumulated precipitation (rain and snow) exceeding 1, 5, 10 and 20 mm (in %). The probabilities are based on the number of forecast members which meet the criteria (each member is assigned an equal probability of 1/50).
