State Key Project during 9th 5-yr plan(96-908)#Research on Short-term Climate Prediction System in China

Along with rapid development of our country’s economy, not only need more accurate mid-short term climate prediction, but also cry for longer-term climate prediction.Short-term climate prediction is a preceding problem in international atmospheric science and geoscience domains, which also being a most difficult span-subject problem.Because of its‘ important social economy significance and scientific difficult, the project had been ranked as one of 16 state key projects during 9th 5-yr plan.
Through 731 scientists ( including 5 academicians and near 80 professors and researchers) 5yrs’(1996-2000) research, we has achieved whole target to tackle the key problem, established the first short-term operation system over state and regions which has being run successfully for 3 years and provided more than 14 kinds climate products for national and foreign users.
An introduction of  the project

SCSMEX was the first international large-scale experiment led by Chinese scientists, in cooperation with scientists from many countries and regions. Field observations have been completed through common efforts and cooperation. The participating countries and regions are Mainland China, USA, Japan, Vietnam, Thailand, Malaysia, Singapore, Brunei, Philippine, Indonesia, Australia; Taiwan, Hong Kong, Macau and so on.
Research Achievements
1) The Asian monsoon broke out earliest over the SCS and Indo-China Peninsula was well documented. From the viewpoint of synoptic process, its onset was closely related to the early rapid development of a twin cyclone to east of Sri Lanka. The conceptual model of the SCS monsoon onset in 1998 has been put forward. The 50-year time series of the SCS monsoon onset date has also been made. 
2) Two major modes, namely 30-60 days and 10-20 days oscillations have been ascertained. The influences of the abnormal SCS monsoon on the precipitation over the eastern China and its modes have been ensured. Strong (weak) monsoon over the SCS usually leads to little (more) precipitation over the middle and lower reaches in the Yangtze River Basin, and more (little) precipitation in North China. 
3) During the monsoon onset over the SCS there observed a wide variety of organized meso-scale convective systems(MCSs) by using Doppler radar array deployed over the northern SCS. The relationship between large-scale circulations and meso-scale convective systems (MCSs) during the monsoon onset process in 1998 was clearly revealed. It suggested that there be kind of positive feedback mechanism between large-scale circulations and meso-scale convective systems(MCSs). 
4) The SST over the SCS during the early period influenced the early or late monsoon onset date and its intensity. During the monsoon onset, the ocean had a process of the energy release. During the break phase of the SCS monsoon, the ocean demonstrated the process of the energy re-accumulation. There observed obvious differences in the air-sea turbulent flux exchange between southern and northern part of the SCS due to different characteristic features of atmosphere and sea structure in those region. 
5) The impact of intensive observations is increasingly more significant by using the regional models. The Air-sea coupled regional climate model(CRCM)has also been developed under SCSMEX Project . The simulation of the oceanic circulation in1998 produced with the model was comparative with the observation.


On going Projects:
Observational study on the effect of surface condition and atmospheric boundary layer over the Huai River basin on the rainfall anomaly in the flooding season

Through the implementations of the Sino-Japan cooperative in-situobservation experiment, this project, observational study on the Effect of the surface condition and atmospheric boundary layer over the Huai River basin on the rainfall anomaly in the flooding season, is aimed to achieve the high-resolution data of land and atmospheric boundary layer in the valley of Huai River, known as the transition region of dry and wet area in China and characterized by the strong interannual variability of soil moisture in pre-winter and spring. In term of the obtained data set, our studies will focus on the influenceof the pre-wintertime and springtime soil moisture anomalies in the Huai River Basin on the onset and northward march of East-Asia summer monsoon as well as the anomalous rainfall in the flooding season of China. Furthermore, on the basis of the revealed physical mechanism, the rainfall anomalies in pre-winter and spring in the valley of Huai River can be regarded as one of the key factors to improve the empirical seasonal predication skill for the summertime rainfall ofChina. Besides, the obtained data sets and analysis results will favorthe improvement of land surface parameterization of the climate modelsin National Climate Center so as to enhance their forecasting abilityand skills.
