Floods and droughts are commonly-occurring weather hazards around the world. Amid the global climate change, there is an urgent need on behalf of the decision makers to know the risks and frequencies of such events in the future to better prepare adaptation measures. To this end, we analyzed extreme compound events in Iran to quantify frequency of dry (for ≥120 days, rainfall<2mm, Tmax≥30oC) and wet periods (for ≤3 days, total rainfall≥110 mm) using past (1980-2004) and future (2025-2049) climate data; and for some flood-prone regions.
