Climate Change and Prediction

Theory/Methodology

• Variability analysis in temperature, precipitation and soil temperature;
• Correlation analysis between precipitation and soil temperature and moisture;
• Modeling study of impacts of land surface processes on short range climate;
• Development of an simplified nonlinear climate model for theoretical research;
• Globally studied the ensemble prediction method and obtained theoretical results about limit number of ensemble samples, using a simplified climate model;
• Predictability study: obtained theoretical upper limit for daily and monthly prediction;
• Practice in seasonal and annual precipitation prediction: used soil temperature anomaly as the main predictor to predict summer total precipitation. The prediction was provided for final discussion to Chinese Meteorological administration every year in spring. Annual precipitation was also conducted;
• Soil temperature, together with geothermal flow, was also used in earthquake study.
