The Fourth China-Japan Joint Workshop on Lower Atmosphere and Precipitation Study (LAPS) was held in CMA on 19-20 September 2006. 13 experts and doctors from Nagoya University, Chiba University, Okayama University, and 30 experts and students from BCC, CAMS, LAP/CAS, Huaihe River Water Resources Commission/MWR, Nanjing University of Information Science and Technology attended the workshop. Dr. Li Weijing, Chinese Project leader and Deputy Director-General of BCC, presided the opening ceremony. Mr. Lin Hongzhu, Department of Scientific and Technological Development/CMA, and Prof. Kenji Nakamura from Nagoya University made a speech at the opening ceremony. Academician Ding Yihui from BCC attended the workshop.
Prof. Nakamura is the former Director-General of International Project Office of GAME/GEWEX, and also the former Director-General of Institute of Atmospheric Water Cycle for two terms. He’s joined the cooperation with CMA since 1990s. In his speech, he exclaimed the rapid development of CMA and Beijing, thanked CMA for its support to LAPS project and BCC for its kind cooperation. He hopes to continue the cooperation with CMA.
LAPS is a field experiment and research project carried out jointly by BCC and Nagoya University, it’s based on the observation and research of the Huaihe River Basin Energy and Water Cycle Experiment (HUBEX). LAPS focuses on the mechanism of the interaction of boundary layer atmosphere and land and its impact on the East Asian Monsoon, and improve seasonal rainfall prediction of China and Japan for the ultimate goal. The project aims in getting high-resolution data of different seasonal abnormal land conditions and characteristics of the various elements of atmospheric boundary layer, through Chinese typical transitional zone of north-south dry climate and long-term observation in southern Japan, and reveal the surface characteristics of the Huaihe River in winter-spring and the physical mechanism of abnormal precipitation in flood season. So as to improve the land surface parameters of climate model and precipitation predict capability.
From August 2003 to January 2006, we carried out continuous observation in Anhui Province, and in the summer of 2004 and 2005 we launched the encryption observation in Fuyang, and start the artificial rice mobile observation in Shouxian (e.g. long-wave radiation in land, soil moisture, surface temperature, soil transpiration, CO2, crops growing, etc.).
The workshop aimed at reviewing and exchanging observation and research results. The meeting mainly discussioned the following aspects: 1) the influence mechanism and climate characteristics of large-scale weather system of Huaihe River basin in the rainy season, 2) the physical characteristics and simulation of mesoscale Meiyu front system, 3) the interaction of boundary layer atmosphere and land atmosphere in Huaihe River basin, 4) the application of atmospheric detection and remote sensing technology. Totally 24 academic reports had been exchanged and the key scientific issues and the next working emphasis had been discussed in the meeting.
