Abstract: | The frequency of extreme rainfall is increasing worldwide. Research on extreme rainfall is important for preventing floods and hail damage caused by these events. Dual-polarization weather radar is a very useful remote sensing instrument to observe storms over a wide spatial domain instantaneously. This paper focuses on characterizing the extreme rainfall event over the United Arab Emirates (UAE) that occurred on April 15 and 16, 2024. This extreme event was the heaviest rainfall in the past 75 years over the UAE, with more than 250 mm of rainfall and hail reported. The wide spatial coverage of radar network in the UAE observed extreme rainfall every 6 minutes. The radar network consists of six C-band dual-polarization weather radars, covering up to 1000 km in longitude and 800 km in latitude. The microphysics of storms are studied using profiles of reflectivity (Z), differential reflectivity (Zdr), and correlation coefficient (ρhv) observed from dual-polarization weather radars. The structures of the storm that caused the extreme rainfall are compared to the normal convective storm that occurred in the UAE. Radar observations are compared to satellite passive microwave observations. |
