MIRAI INDIAN OCEAN CRUISE FOR THE STUDY OF THE MJO-CONVECTION ONSET

Project Description
The Mirai Indian Ocean Cruise for the Studies of the MJO-Convection Onset project investigates the characteristics of the atmospheric and oceanic variability in the central-eastern Indian Ocean and in the boreal fall season for the study on the onset of the MJO-convection. Various atmospheric and oceanographic observations using Doppler radar, radiosonde, surface met monitor, CTD, ADCP, and so on will be carried out as a stationary observation at (0, 80.5E) about one month from the late October 2006, focusing on the vertical structure of water vapor, clouds, divergence field as well as diurnal cycle of sea surface temperature and surface flux. It is highly remarked that the combination with the buoy network deployed in this region is essential for this experiment, since it helps not only to study the heat budget but also to capture the long-term and wide-range atmospheric and oceanic features. In addition, as the MJO propagates eastward, zonal extension of the observational area is strongly desired. Thus, meteorological observations at Maldives Islands will also be conducted under the cooperation with the Maldives officials.
