Abstract

Mesoscale Convective Complex (MCC) was firstly introduced by Maddox on 1980. MCC is a type of Mesoscale Convective System (MCS) which has more than 100.000 km2 in cloud region size and more than 6 hours lifetime that can generate severe weather and continuous rain. On 9 May 2018, an MCC develops in southern Papua. This research aimed to find out the MCC growth characteristics, the conditions of the atmosphere, and the distribution of rainfall around southern Papua. Infrared (IR) satellite imageries show that the MCC develops up to > 300.000 km2 with 14 hours of existence. The rainfall distribution from Global Satellite Mapping (GSMaP) imagery depict a 800 km rain area with varied rainfall intensity which reaches 40 mm/hour. Atmospheric condition analysis is conducted on several paramaters such as wind, relative humidity, divergence, and vertical velocity from European Centre for Medium-Range Weather Forecasts (ECMWF) model data. Based on the descriptive analysis result, convergence occur on the lower troposphere of southern Papua while the MCC growth phase and accompanied by the high relative humidity in 850 hPa level. Time series of vertical velocity also represent that there is growth and dissipation process of MCC in southern Papua on 9-10 May 2018.
