For much of 2021, drought gripped southern Iran, parching crops, drying wells, and fueling protests over water. The first week of 2022 brought the opposite problem—a series of potent rain and snow storms overwhelmed rivers and unleashed widespread flooding.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured imagery of flooding in southern Iran on January 7, 2022. For comparison, the second image shows the same area on December 14, 2021, before the storms hit.

Dry land appears brown; vegetated areas are green. Areas covered by water are dark blue.........
