Abstract

Abstract

By using the data of temperature, precipitation and typhoon year book from 1951 to 1995, the warm and cool summers are defined and identified, and features of monsoon rainband distribution and the abnormal activities of typhoons over the East China Sea as well as their linkages to ENSO are statistically analyzed. The results show that the activities of typhoons and the monsoon rainband distribution in warm summers are very different from those of cool summers. Meanwhile, the SSTA over equatorial Pacific exhibits distinctively contrast during warm summers and cool summers. In addition, the physical concept model about the teleconnection is given.
- The middle and lower reaches of the Yangtze River;
- Warm summer;
- Cool summer;
- Typhoon Monsoon rainband
