| Research Abstract |
The energy and water cycle in the subtropical monsoon region of the East Asia is characterized largely by Baiu/Meiyu front in summer. One of purposes of GAME/HUBEX is to study the evolution of mesoscale cloud system. Main objectives of this study are to clarify roles of a mesoscale cloud system in time variation of regional-scale energy and water cycle and to reveal evolution of a mesoscale cloud system and its response to time variation of land-surface system.
Following 1998, HUBEX group also performed meteorological observation in 1999 : surface flux observations and the intensive field observation of meteorology and hydrology in June and July (Baiu season). Main observations are as follows, radiosonde observations at 15 points 4 times a day, weather-radar observations at Fuyang, Doppler radar observations at Shou-xian and Feng-tai, dense raingauge observations, AWS long term monitoring, and flux observations.
The long term monitoring of flux are continued since the last year. Synoptic-scale situation was largely different from the last Baiu season. During the intensive field observation, several types of precipitation were observed. In particular, precipitation was significant during the period from 21 June to 8 July.
Modeling studies have been performed about a cloud cluster observed over the China continent during the IOP using JSM (Japan Spectral Model), MRI-NHM, and Yamasaki's model. The cloud cluster was successfully simulated by these models and the results were compared with observation.
HUBEX group organized international conferences and workshops : the workshop Xi'an, China on 3-9 November 1999, the international conference in Sapporo, Japan on 12-14 September 2000 and international conference entitled as"The Third GAME-HUBEX Workshop on Meso-scale Systems in Meiyu/Baiu Front and its Hydrological Cycle" in China in December 2001. Many papers were presented in there conferences and fruitful discussion was carried out.
