The evolution of Mesoscale Convective System (MCS) around the Greater Jakarta area on 9 February 2015 using MTSAT Satellite

摘要

The Greater Jakarta (GJ) area received serious attention from the government in the last 10 years due to the frequent occurrence of flood problems during the rainy season. Extreme rain events which leads to flooding often associated with highly convective cloud systems. One of the phenomena describes the presence of a broad convective cloud system known as a mesoscale convective system (MCS). The objective of this study is to describe the MCS evolution during heavy rainfall event on February' 9, 2015. The Multi-functional Transport Satellite (MTSAT) imagery data was used for identified the MCS. The system developed from morning of February 9. 2015 until the daytime. The results showed that there was a concentration of convective clouds around GJ area. Although the convective cloud area tends to be small (<50,000 km2), heavy rainfall was observed in the study area. This shows that the rain that occurred was quite heavy and may be the cause of the flooding in the study area.
