The Analysis of Anomalous Climate in Eastern China in Summer 2006——Verification of Seasonal Climate Predictions of the Institute of Atmospheric Physics,Chinese Academy of Sciences

The prediction of summer rainfall by the Institute of Atmospheric Physics,Chinese Academy of Sciences is tested.The rainfall of the prediction in Eastern China is close to the observation.The severe drought of Chongqing and Sichuan was not forecasted,nor was the heavy flood in southern China.The feature of the abnormal climate in the summer of 2006 is analyzed.The intraseasonal change of summer monsoon played an important role in the climatic anomaly of the rainfall in China.It is still very difficult to predict the anomalous rainfall due to intraseasonal change of the summer monsoon.
