Motivated by the need to quantify the internal structure of the rainy season and thereby improve the understanding of rainfall seasonality, this study develops a new methodology based on daily precipitation data. The approach decomposes each rainy season into rain modes, separately for seasonal and intra‐seasonal timescales. Daily rainfall is approximated by a sum of Gaussians, capturing the gradual onset, peak, and decay of r...

The Red‐Sea Trough (RST) extends toward the Levant from the south and is mostly associated with dry conditions. This study analysed the rarer type, rain‐producing RSTs, referred to as ‘wet RSTs’ (WRST), using data from 1958 to 2019. A WRST archive was established, based on rain data from a study region covering the arid part of Israel, the region where this system is most active. The study also aimed to find an atmospheric pro...
