Indeks Labilitas Udara Untuk Memprediksi Kejadian Badai Guntur Pada Periode Puncak Musim Hujan Tahun 2016

Abstract: IntisariPrediksi kejadian badai guntur menjadi perhatian masyarakat luas karena biasanya disertai dengan curah hujan yang tinggi, terutama untuk wilayah rawan banjir seperti provinsi DKI Jakarta. Penelitian ini bertujuan untuk analisis potensi hujan disertai badai guntur dengan menggunakan data radiosonde, analisis indeks labilitas berdasarkan parameter yang didapat dari radiometer dan analisis tren indeks labilitas 6 jam sebelum kejadian hujan. Ada beberapa tanggal yang menjadi perhatian yaitu hari dimana kej… Show more

“…For the average KI index value throughout 2019-2020, it was obtained at 29.33 o C which shows the convective motion of the cloud due to the temperature difference between the atmosphere so that the potential for the appearance of storm clouds is quite high [11}. The average value of the CAPE index obtained at 1395.25 J/Kg shows that the convection process of air masses rises vertically warmer than the surrounding air, causing atmospheric instability [12]. The calculation of the correlation coefficient is used to find out how much the correlation between the wind shear that occurs and the values of the atmospheric lability index, the wind shear data used is the data at all altitudes shown in Figure 1-3 and the atmospheric lability index values are shown in Figure 4.…”

“…Kondisi atmosfer yang labil dapat mengangkat partikel-partikel yang terlepas di udara hingga ke level yang tinggi, sehingga dapat membuat kondisi udara di permukaan menjadi bersih. Data vertikal atmosfer yang diperoleh dari data Radiosonde dapat digunakan untuk melihat kelabilan atmosfer (Zahroh et al, 2017) Pada awal Maret 2020, di Indonesia telah ditemukan kasus pasien yang terjangkit virus COVID-19. Adanya wabah tersebut menyebabkan berbagai macam aktivitas seperti sekolah dan perkantoran harus dilakukan dari rumah atau biasa dikenal dengan istilah WFH.…”
