Sea breeze observation in Bogor based on 2016 Intensive Observation Period (IOP)

Land-sea breeze circulation plays an essential role in local weather development. The different characteristics of land and sea, the air movement from and towards the sea may give different effects on convective activity and to the transport of atmospheric particulates. Observational and modeling studies on land-sea breeze circulation in Indonesia have been done to investigate various phenomena in the atmosphere. This study aimed to inspect the sea breeze circulation over the area of Jakarta, Bogor, Depok, Tangerang, Bekasi (JABODETABEK) using data from the Intensive Observation Period (IOP) in 2016. The sea breeze circulation was examined using wind and relative humidity profiles. The movement of convective cloud was observed using X-band Furuno Radar. The result showed that there had been inland propagation of sea breeze, albeit its vague effect in Bogor, West Java. The inland sea breeze may encounter another local weather system resulting in the convergence area somewhere that may result in heavy rains. However, the monsoonal wind has a distinct effect on determining the prevailing wind in one area.
