Abstract

Tulisan ini mencoba untuk menganalisis aktivitas petir menggunakan Lightning Detector sepanjang tahun 2009 dengan radius sekitar 10 km sekitar Bandung. Tujuan analisis adalah untuk identifikasi potensi hubungan antara parameter petir yaitu Cloud-to-Ground (CG) dengan curah hujan lebat di atas 50 mm/hari. Hasil analisis menunjukkan hubungan yang kuat antara CG dan curah hujan lebat serta dominasi CG- (66.1%) sepanjang musim dengan puncak aktivitas pada MAM (43.6%). Pemahaman akan keganjilan aktivitas kilat akan memberikan informasi penting dalam struktur, pertumbuhan awan, labilitas atmosfer ataupun sebagai warning (peringatan) cuaca ekstrim.

 

The objective of this paper is to analyze the lightning activities using Lightning Detector during the year 2009 with a radius about 10 km around Bandung. The purpose of this analysis is to identify potential relationships between lightning parameters i.e Cloud-to-Ground (CG) with torrential rainfall more than 50 mm/day. The results showed a strong relationships between CG and torrential rainfall and dominance of CG- (66.1%) throughout the season with a  peak at MAM (43.6%). Understanding of the peculiarities of lightning activity will provide important information in the structure, the growth of clouds, atmospheric labilitas or as a warning extreme weather.
