| Research Abstract |
The East Asia is characterized by a significant rainy season, diverse vegetation and land uses in different types of climate regions such as tropical, subtropical and extratropical. We study multi-scale water cycle in the atmosphere and the land surface to clarify the response of water cycle to changes of the continental scale atmospheric environment and land surface conditions. In this study, we performed intensive observations in the Huaihe River Basin of China and in Thailand.
In 1998, we performed meteorological observation during the period from May to August, surface flux observations in each season and the intensive field observation of meteorology and hydrology in June and July (Baiu season). Main observations are as follows : radiosonde observations at 21points 4 times a day, weather-radar observations at 6 points, Doppler radar observations at Shou-xian, Feng-tai and Huai-nan, dense raingauge observations, and flux observations in paddy field, farmland, forest and lake. During the intensive field observation, a record-breaking flood occurred in the Yangtze River region. A large amount of important data were obtained by the field observation.
Following 1998, we performed meteorological observation in 1999 : surface flux observations and the intensive field observation of meteorology and hydrology in June and July (Baiu season). 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.
