| Abstract: | Based on air temperature and precipitation data from 1951 to 2009,the distributions of heavy rain in Quzhou were analyzed.The change characteristics of the regional meteorological elements were discussed.The results indicate that the mean annual air temperature has an increasing trend in the recent 59 years in Quzhou,especially in the early stage of 1990s.Compared with the mean annual air temperature of 1950s,the average temperature during 1990-2009 has increased by 0.68 ℃.Warming is more obvious in winter than in summer.The average of the extreme temperature is also in an increasing trend,and it has the obviously seasonal variation.The ascending amplitude of the maximum temperature is larger than that of the minimum temperature.There is a 4-5 years cycle for precipitation in Quzhou.The richer and less precipitation years alternate,while the changes of the annual precipitation are not significant.The distributions of precipitation have the obviously seasonal characteristics in a year,and precipitation is higher in summer and lower in winter.The change amplitude of annual precipitation is stable and rainfall is less before 1966,while rainfall increases gradually after 1966 and it reaches peak in 1975,and then decreases gradually.The abrupt change of precipitation occurs around 1980,and oscillation increases. |
