Cruise Code MR04-K01 :: Main Research Theme The Study of Air-Sea Interaction in the Tropics :: Objectives The aim of the cruise is to obtain the various data especially focussing on precipitation to reveal its mechanism of the convection developed over the warm water pool in the tropical western Pacific region, where air-sea interaction is very active. The evaluation of the precipitation effect onto the ocean surface structure is also an important theme of this study. Main target is an well-organized cloud cluster that is often observed during the active phase of the equatorial intraseasonal oscillation (Madden-Julian Oscillation). :: Outline of Observation Stationary observation near the area (2N, 138.5E) will be conducted for most observation period as much as possible. (Maximum two weeks is expected.) Continuous Doppler radar observation and the launch of radiosonde conducted every 3 hours are the main observation items. In addition, CTD casting down up to 1000m depth, shipboard ADCP, surface meteorological measurement, ceilometer observation will also be conducted routinely. :: 5. Main Research Area Tropical Western Pacific Ocean 135E-145E, 2S-8N (Stationary observation point is scheduled to be at 2N,138.5E.) ::
