Characteristics of Observed Phenomena during the YMC-Boreal Summer Monsoon study in 2018
Abstract
As a part of the YMC (Years of the Maritime Continent) campaign, Intensive Observation Period (IOP) of the YMC-Boreal Summer Monsoon study in 2018 (YMC-BSM 2018) was set during July 1 to August 31, 2018. The YMC-BSM 2018 is designed to study boreal summer monsoon by conducting various observations at selected sites, where local unique phenomena are often observed. One key topic of the YMC-BSM 2018 is atmospheric convection associated with northward propagating BSISO (Boreal Summer Intra-Seasonal Oscillation). To study offshore propagation of diurnal cycle of rain and its relation to BSISO, Doppler radar was deployed in the west coast of the northern Luzon, Laoag area, in Philippines, while radiosonde soundings were enhanced both at Laoag and at Koror, in Palau. In addition, to study air-sea interaction around the Philippine Sea, three autonomous unmanned surface vehicles equipped with surface meteorological station, GNSS receiver, and ADCP were launched from Palau to occupy 8/10/12N along 132E. On the other hand, interaction between upper troposphere and lower stratosphere was intensively studied by launching special sondes equipped with ozone-sensor and high accurate hygrometer at Hanoi and Ho Chi Minh in Vietnam, and at Kototabang, in Indonesia. During the IOP, near real-time prediction using NICAM were also performed. In this presentation, overview and preliminary observed results of the YMC-BSM 2018 will be introduced.
