Abstract

Indeks stabilitas memiliki nilai ambang batas dan akurasi nilai ambang batas yang beragam terhadap prakiraan terjadinya awan Cb dan thunderstorm di tiap wilayah, sehingga dengan kondisi tersebut indeks stabilitas sangat menarik untuk dikaji tak terkecuali di Bandara Internasional Sultan Hasanuddin. Indeks stabilitas sangat beragam jenisnya, namun yang umum digunakan dalam memprakirakan terjadinya awan Cb dan thunderstorm adalah SI, LI, TTI, SWEAT, KI, dan CAPE. Pada penelitian ini, ambang batas indeks stabilitas terhadap kejadian awan Cb dan thunderstorm hampir identik satu sama lain dengan bulan Desember merupakan bulan dengan ambang batas terendah dan tertinggi bagi tiap-tiap indeks stabilitas terhadap kejadian awan Cb dan thunderstorm. Akurasi ambang batas indeks stabilitas terhadap kejadian awan Cb lebih baik dibandingkan akurasi ambang batas indeks stabilitas terhadap kejadian thunderstorm yang disebabkan oleh awan Cb yang muncul di suatu wilayah belum tentu menghasilkan thunderstorm namun ketika thunderstorm terjadi di suatu wilayah maka thunderstorm tersebut disebabkan oleh adanya awan Cb.

Abstract

Sistem konvektif Cumulonimbus merupakan kumpulan awan yang terdiri dari awan Cumulonimbus dan awan awan lain yang membentuk sebuah sistem, yang dapat menimbulkan cuaca signifikan. Karakteristik fisis dan dinamis Cumulonimbus diperoleh menggunakan radar cuaca C-Band pada musim peralihan dan musim hujan September hingga Februari 2016 – 2022, berpusat pada radius 150 km di sekitar Bandara Internasional Sultan Hasanuddin Makassar. Sembilan tipe morfologi sistem konvektif meso-β ditemukan dengan panjang awan 20-220 km dan panjang rata-rata awan 65 km. Sistem konvektif dominan membentuk sistem linier. Morfologi yang paling banyak terbentuk adalah sistem linier Trailing Stratiform, dan sistem seluler Cluster of Cells. Pada musim peralihan, inisiasi Cumulonimbus dominan di dataran tinggi dan pada musim hujan inisiasi dominan di laut pesisir. Secara umum Cumulonimbus matang di laut pesisir pada siang hari. Cluster of Cells dan Bow Echo adalah sistem yang paling aktif di darat, dengan windshear yang relatif lebih kuat dari semua sistem konvektif. Sistem sebagian besar berpropagasi dengan lambat. Vertical wind shear paling besar terjadi pada lapisan 0,3 – 2 km. Verifikasi dari media massa dan laporan pilot menunjukkan bahwa Cumulonimbus dapat menyebabkan bencana hidrometeorologi dan mengganggu penerbangan.

Abstract

The impact of climate change has emerged as a strategic issue threatening the national interests and environment, particularly in the context of Tana Toraja in the tropical region of Indonesia. The process of climate change, influenced by both natural factors and human activities, has led to a global increase in temperatures and climate anomalies. The risks of natural disasters, especially those related to rainfall such as floods, landslides, and the spread of diseases, are on the rise. The Indonesian government needs to design region development strategies with low greenhouse gas emissions and control deforestation. This study employs a qualitative descriptive method and utilizes data from the Pongtiku Toraja Meteorological Station from 2000 to 2019 to analyze the patterns of climate change and the impact of the El-Nino Southern Oscillation (ENSO) in Tana Toraja. The research findings indicate a decrease in the annual average air temperature, an increase in air humidity, and a shift in rainfall patterns towards an equatorial climate type. The impact of ENSO on air temperature, humidity, and rainfall is variable. Predictions suggest a decrease in rainfall, but combined analyses show an average increase of 4.5% per year until 2029. This conclusion provides a holistic overview of climate dynamics in Tana Toraja, crucial for understanding and planning adaptation for the future.
