Global warming is increasing the frequency and intensity of compound climate events, highlighting the need to understand their patterns and impacts. The physical characteristics of heatwaves (HWs) followed by extreme precipitation events (EPs) across 13 subregions of the Middle East (ME) are investigated on a 25-years period from 2000 to 2024. The frequency, duration, and intensity of HWs are quantified using maximum temperature of European Centre for Medium-Range Weather Forecasts (ECMWF) ERA5 reanalysis. The final product of Integrated Multi-satelitE Retrievals for Global Precipitation Measurement (IMERG-F) is used for analyzing EP following HWs, as it demonstrated the highest accuracy in a comparative evaluation of six satellite-based precipitation products against rainfall data from 120 weather stations. Iran, Türkiye, and Yemen exhibited the highest HW intensity, frequency, and duration, respectively. Although July showed the highest number of HWs, May and September demonstrated the highest success rates for a shift toward EP within a 36-h window, reaching 58.5 % and 57 %, respectively. The last day of HWs and the subsequent day accounted for the majority of EPs, contributing 21.3 % and 39.7 % of the total EP, respectively. An increasing trend in EP contributions following HWs has been observed since 2013, with a slope of 29 %. The contribution to the probability of EP following HWs was notably higher in Saudi Arabia and Egypt, about 8 and 11.6 times greater than climatology, respectively, underscoring their significance as potential water resources. EPs following HWs contributed 62.6 % of the total precipitation, compared to 38.4 % from climatological EPs, and had a 72.2 % occurrence probability versus 27.8 % in the climatology. EP intensity presented a positive trend across the ME, with statistically significant increases in Iran and Yemen, exposing the higher HW intensity and duration. The strong correlations between HW intensity and duration and subsequent EP (R2 = 0.87 and 0.81, respectively) are characterized by slopes of 0.36 °C and 2.4-day correspond to an increase in EP rate. Satellite precipitation data revealed high levels of convective and warm rain, liquid water content, and higher droplet size in EPs following HW relative to climatological EPs. Finally, the ME is subdivided into three regions (Türkiye, Iran, and Arabian Peninsula/Egypt) to enable region specific analysis of large-scale atmospheric conditions before, during, and after EPs. Notably, across all regions, a pronounced convergence of moisture flux from adjacent water bodies is observed 48 h prior to rainfall, supplying sufficient atmospheric moisture. During the EPs, low geopotential height systems, whether weak or strong, contributed to temperature reduction, facilitating atmospheric saturation and subsequent EP development particularly in Türkiye and Iran.
