Abstract
ENSO (El Nino Southern Oscillation) is a form of climate deviation in the Pacific Ocean which is characterized by an increase in Sea Surface Temperature (SST) in the Central and Eastern parts of the equator which affects the increase and decrease in rainfall. The rainy season in Indonesia generally occurs from October to March and the dry season occurs from April to September. This study aims to determine the effect of the ENSO phenomenon on cloud distribution and rainfall variations in Tangerang District. The data used is in the form of secondary data obtained from the BMKG Meteorology Budiarto including rainfall data, cloud cover, wind direction and speed. In addition, Southern Oscillation Index (SOI) data is also used, sourced from the Australian Bureau of Meteorology (BOM) website. The data analysis used is surface weather analysis and pearson correlation analysis. The results showed that based on surface weather analysis, ENSO events had an effect on cloud distribution in Tangerang District. The clouds that dominate when the ENSO phenomenon occurs are Cumulus and Nimbrostratus clouds with a cloud cover of 4-8 octaves. Meanwhile, the results of the correlation test showed that ENSO had an effect on rainfall variations in Tangerang Regency, both seasonally and annually.

| Additional Information: | ENSO (El Nino Southern Oscillation) adalah salah satu bentuk penyimpangan iklim di Samudera Pasifik yang ditandai dengan kenaikan Suhu Permukaan Laut (SPL) di daerah khatulistiwa bagian Tengah dan Timur yang berpengaruh terhadap peningkatan dan penurunan curah hujan. Musim hujan di wilayah Indonesia umumnya terjadi pada bulan Oktober sampai Maret dan musim kemarau terjadi pada bulan April sampai September. Penelitian ini bertujuan untuk mengetahui pengaruh fenomena ENSO terhadap sebaran awan dan variasi curah hujan di Kabupaten Tangerang. Data yang digunakan berupa data sekunder yang diperoleh dari BMKG Meteorologi Budiarto meliputi data curah hujan, tutupan awan, arah dan kecepatan angin. Selain itu digunakan juga data Southern Oscillation Index (SOI) yang bersumber dari website Bureau of Meteorology ( BOM) Australia. Analisis data yang digunakan yaitu analisis cuaca permukaan dan analisis korelasi pearson. Hasil penelitian menunjukkan bahwa berdasarkan analisis cuaca permukaan peristiwa ENSO berpengaruh terhadap sebaran awan di Kabupaten Tangerang. Awan yang mendominasi pada saat terjadi fenomena ENSO yaitu awan Cumulus dan Nimbrostratus dengan tutupan awan 4-8 okta. Sedangkan hasil uji korelasi menunjukkan bahwa ENSO berpengaruh terhadap variasi curah hujan di Kabupaten Tangerang baik secara musiman maupun tahunan. | |||||||||
