| Abstract: | Based on the observational data and numerical prediction products etc.,by using the methods of statistic and diagnostic weather analysis,the characteristics and causes of the disasters event are analyzed.Results show that low average temperature,lasting for a long time and serious frozen and disasters are the three characteristics.causes analysis indicated that abnormal atmospheric circulation,such as long time stable Mongolia high pressure,construction and collapse of trough and ridge in high latitude,active westerly south branch trough in low latitude and the interaction of cold and warm air in the South China play an important role for the extreme event. |
