KARAKTERISTIK HUJAN DAN AWAN PENGHASIL CURAH HUJAN HARIAN TINGGI BERDASARKAN DATA MICRO RAIN RADAR (Studi Kasus : Wilayah Dramaga, Bogor)
Main Article Content
Abstract
Intisari
Kejadian hujan di wilayah Bogor yang seringkali dikaitkan dengan kejadian banjir di wilayah Jakarta dan sekitarnya menjadi dasar pentingnya studi karakterisasi awan-awan penghasil curah hujan harian tinggi di wilayah Bogor tersebut. Suatu instrumen cuaca, yaitu micro rain radar (MRR), Â merupakan instrumen yang cukup potensial dalam hal ini, tetapi belum banyak dimanfaatkan di daerah tropis, khususnya Indonesia. Dalam penelitian ini, dilakukan karakterisasi hujan dan awan-awan penghasil curah hujan harian tinggi di wilayah Dramaga, Bogor berdasarkan data MRR. Hasil analisis terhadap data MRR ini dengan cukup jelas memperlihatkan bahwa kejadian hujan dengan akumulasi curah hujan harian tinggi di daerah tersebut utamanya dihasilkan oleh awan-awan konvektif yang mencapai ketinggian puncak awan sekitar 4.5 km, dengan kejadian hujan berkisar pada siang, sore, dan malam hari.

Abstract
Rain events in Bogor area that are often associated with flood occurrences in Jakarta and surrounding areas become important basic of characterization studies of clouds producing high daily rainfall in the Bogor area. A weather instrument, namely micro rain radar (MRR), is an instrument that is considerable potential in this regard, but has not been widely used in tropics, especially Indonesia. In this study, characterization of rain and clouds producing high daily rainfall in Dramaga, Bogor based on MRR data were conducted. Analysis results of the MRR data quite clearly show that occurrences of rain with high daily rainfall accumulation in the area were mainly produced by convective clouds which reached a height of cloud tops about 4.5 km, with rain events happened generally at afternoon, evening, and night.
