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.

东亚亚热带季风地区的能量和水循环在很大程度上以夏季的Baiu/Meiyu阵线为特征。游戏/Hubex的目的之一是研究中尺度云系统的演变。这项研究的主要目的是阐明区域尺度能量和水周期的时间变化中的中尺度云系统的作用，并揭示中尺度云系统的演变及其对土地表面系统时间变化的响应。依次遵循1998年，Hubex Group在1999年在1999年进行了气象观察：表面通量观察和七月的观察（METERIDENS和MENT OFFERIDENS）和MENT GROID OFDERIDEN和MENT OFFICERIDENS和MENT OFDERIDENS（MENT OFFERS）（6. METEREDISS）（6. MENTEREDISS）（6. MENTEREDING of METEREDISS和METE）（6月）。主要观察结果如下，每天15分的辐射观察结果，富阳的天气射线观察，多普勒雷达在舒 - 西安和冯 - 泰进行的多普勒雷达观察结果，浓密的raingauge观察，AWS的长期监测和通量观察。天气级的情况与上一个Baiu季节大不相同。在密集的田间观察期间，观察到了几种类型的降水。特别是，在6月21日至7月8日的期间，对使用JSM（日本光谱模型），MRI-NHM和Yamasaki的模型进行了对中国大陆上观察到的云簇进行了重大降水。 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年。在那里发表了许多论文，并进行了富有成果的讨论。
