Rainfall microphysical characteristics observed in the Jakarta flood events.

ABSTRACT: There has been a dramatic increase in flood events over Greater Jakarta since 2019. However, little study has been found regarding physical characteristics of rainfall during flood events. This study investigates the rainfall drop size distribution during the three cases of severe flood events in the Jakarta area on 31 December 2019-1 January 2020 (Case 1), 15-16 July 2022 (Case 2), and 6-12 October 2022 (Case 3). The characteristic of rainfall drop size is analysed and categorised based on stratiform, convective, and mixed convective-stratiform rainfall. This research used the Automatic Weather Station, Laser Precipitation Monitor, and ERA5 reanalysis datasets from December 2019 to October 2022. Overall, results show that raindrops with particle diameters up to 4 mm exist during the three
