Pemanfaatan Data Satelit Himawari 8 dalam Analisis Kejadian Hujan Lebat di Jombang

Abstract

On February 2 2021 flooding struck Jombang damaging 38 houses and public facilities due to heavy rainfall from cumulonimbus clouds The analysis of convective cloud development using Himawari 8 Satellite with RGB Day Convective Storm 24H Microphysics Airmass and Cloud Convective Overlay methods revealed that the microphysics phase occurred in two different phases on February 1 and 2 The peak temperature of the Cb cloud during the development phase ranged from 20 to 60 C Convective cloud clusters originated from the Java Sea and the Southern Sea The peak cloud formation occurred at 12:00 UTC on February 1 and 2 Increased updraft and thickness intensity strengthened convective cloud formation During the decay phase downdraft increased with a decrease in cloud distribution as observed in the Day Convective Storm and 24H Microphysics images < em>< p>
