Identifikasi Curah Hujan Ekstrem Menggunakan Metode Analisis Mesoscale Convective Complexe (MCC) Dari Data MTSAT IR1

Abstract

Identification of Mesoscale Convective Complexes (MCC) was done using infra-red image data (IR1) of the Multi-functional Transport Satellite (MTSAT) to create algorithms for use in the detection of MCC from IR1 image data which built by combining multiple criteria of the extent of cloud cover, eccentricity and lifetimes. The linkage for MCC with extreme rainfall is done spatial analysis to analyze the evolution of the development of MCC at each phase is the initial phase, maximum phase and the dissipation phase of MCC. In this study, we also use surface wind from CCMP data to analyze the movementof MCC with seen the surface vectors wind anomaly at each phase of the MCC. And we use also TRMM rainfall data to analyze the influence of MCC on extremes rainfall. MCC can produce extreme rainfall through the mechanism of cold pool with a new convection cell formation system that induces the growth of convection around it so as to make the growth of significant convective clouds around it so that it can lead to extreme rainfallHal. 283-29
