淮河流域能量和水分循环研究进展

The main scientific achievements of the first China-Japan cooperative GAME/HUBEX experiments:A historical review

1998和1999年夏,中国与日本科学家合作在安徽省淮河流域进行了第一次大规模的能量与水循环试验(WCRP/GEWEX/GAME/HUBEX),其重点是研究东亚梅雨锋系的多尺度,多系统结构、特征、生命史、发生发展机理及其引起洪涝灾害的原因。这是第一次中日合作的气象与水文联合观测试验,在此加强观测的基础上,双方进一步进行了长达5年的资料整理分析和科学研究工作,整个淮河流域能量与水循环试验与研究取得了全面和丰硕的成果。文中介绍了该计划所取得的主要成果,并以现在科学进展的视野重新评估这些成果的科学意义和不足,为进一步开展新的淮河与长江中下游梅雨科学联合试验提供经验和新的研究目标。

In the summers of 1998 and 1999, Chinese and Japanese scientists cooperatively conducted the first large-scale energy and water cycle experiment in the Huaihe River Basin, Anhui province of China(WCRP/GEWEX/GAME/HUBEX). The major objective of this field experiment(HUBEX) was to investigate the multiple-scale structure characteristics, the life cycles, the genesis and development mechanisms of the Meiyu system in East Asia as well as the cause of related flooding disasters. It was a joint ChinaJapan cooperative meteorological and hydrological observation experiment. On this basis of the intensive observations, the two partners continued to conduct a follow-up research for another five years to collate and compile data, and perform analysis and scientific research. It can be concluded that the HUBEX project had yielded comprehensive and remarkable achievements. This paper introduces the major scientific results derived from this project and reassesses their merits and shortages for the purpose to provide useful experiences and propose new research targets as well as prospects for the initiation of a new joint scientific Meiyu experiment in the middle and lower Yangtze River Basin.
