Identifikasi Karakteristik Mesoscale Convective Complex (MCC) di Selat Makassar

Introduction

Identifikasi karakteristik mesoscale convective complex (mcc) di selat makassar. Identifikasi dan analisis karakteristik Mesoscale Convective Complex (MCC) di Selat Makassar menggunakan citra satelit Himawari-8. Pelajari durasi, luasan, dan dampaknya.

Abstract

Awan Konvektif berupa tutupan awan yang cukup besar dan memenuhi karakteristik Mesoscale Convective Complex (MCC) telah terjadi di wilayah Selat Makassar. Tutupan awan konvektif skala meso ini memiliki ciri durasi yang cukup panjang, bentuk semi melingkar dan memiliki pola tutupan awan yang besar. MCC ini juga mengakibatkan adanya peningkatan kecepatan angin dan ketinggian gelombang pada wilayah yang dilalui. Pengolahan MCC ini menggunakan data citra satelit Himawari-8 kanal inframerah dengan algoritma yang telah dibangun dan berdasarkan karakteristik MCC yang ada di Indonesia. Karakteristik berupa luasan, durasi dan nilai eksentrisitas dari MCC ditampilkan dalam hasil olahan penulisan ini. Hasil dari penelitian ini memperlihatkan posisi dari MCC, pergerakan dari MCC dan juga akibat yang ditimbulkan dari kluster awan MCC. Tercatat durasi MCC yang terjadi di Selat Makassar selama 8 jam dan memiliki lokasi terjadinya di lautan. Hasil akhir dari analisis ini menghasilkan koordinat lintang dan bujur, serta luasan piksel awan dan juga nilai eksentrisitas. Verifikasi dilakukan dengan mengambil data gambar citra satelit BMKG untuk mengkonformasi keberadaan awan MCC.

Review

This manuscript presents a focused study on the identification and characterization of Mesoscale Convective Complexes (MCCs) within the Makassar Strait, a region known for its dynamic weather patterns. The research aims to delineate the specific characteristics of these significant convective systems, which are known to influence local weather and maritime conditions. Given the potential impact of MCCs on navigation and coastal communities, this study addresses a relevant topic with direct implications for meteorological understanding and operational forecasting in Indonesia. The use of Himawari-8 satellite data, a state-of-the-art platform, suggests a robust approach to data acquisition. A key strength of this work lies in its detailed characterization of the observed MCCs. The abstract highlights specific features such as their semi-circular shape, large cloud cover, and crucially, their long duration, exemplified by an 8-hour event over the ocean. The study's methodology, employing Himawari-8 infrared channel data with a custom algorithm tailored to Indonesian MCC characteristics, appears sound for identifying and quantifying parameters like cloud area, duration, and eccentricity. Furthermore, the explicit mention of verification using BMKG satellite imagery adds a layer of credibility to the findings, confirming the presence and characteristics of the identified MCCs and their observed impacts on wind speed and wave height. While the abstract provides a strong overview of the research, several areas could benefit from further elaboration to enhance the manuscript's scientific depth. Greater detail regarding the "algoritma yang telah dibangun" (custom-built algorithm) and the specific "karakteristik MCC yang ada di Indonesia" (existing MCC characteristics in Indonesia) upon which it is based would significantly improve reproducibility and allow for a better assessment of its novelty and robustness. Additionally, while impacts on wind and waves are mentioned, a more quantitative analysis of these correlations, or a discussion of the meteorological conditions conducive to MCC formation in the Makassar Strait, would enrich the findings. Overall, this is a promising initial investigation, laying important groundwork for understanding severe convective weather in a critical maritime region, but would benefit from a more comprehensive discussion of its methodology and broader implications.
