Analysis of a homogenized dataset from 60 in-situ weather stations across Israel over the past 70 years revealed a significant weekly cycle in precipitation. Generally, weekends exhibit lower precipitation levels, aligning with reduced anthropogenic activity. At some stations, precipitation on a particular weekday was twice that of another day. In addition, for many stations, the day of maximum rainfall shifted during the peri...

High-frequency precipitation variance is calculated in 12 different free-running (non-data-assimilative) coupled high resolution atmosphere–ocean model simulations, an assimilative coupled atmosphere–ocean weather forecast model, and an assimilative reanalysis. The results are compared with results from satellite estimates of precipitation and rain gauge observations. An analysis of irregular sub-daily fluctuations, which was...
