Abstract:
By means of the data of daily 10minute mean maximum wind speed in autumn at Yantai,Weihai and Rizhao, the venues of the 11th Chinese National Games, some climatic features are analyzed. The results indicate that the gale days in autumn decreased annually; the gale weather happened more frequently in the northern coast (Weihai and Yantai) than in the southern coast (Rizhao), especially in Weihai. The analysis based on the synoptic charts from 2001 to 2008 shows that the influencing synoptic systems include lowtrough cold fronts, cyclone, and tropical cyclones, and the weather patterns include “high in the east and low in the west” and “high in the south and low in the north.” Based on the NCEP reanalysis data, the average pressure field for each synoptic system was analyzed, and the mean circulation patterns for various weather systems contributed to gale weather are given.
