摘要
1999年夏季浙江省天气气候特点的分析表明 :当年夏季平均气温明显偏低 ,部分地区季平均气温破历史同期最低值 ,日最高气温≥ 35℃的高温日数明显偏少 ,是凉夏年份 ;全省梅汛期长 ,降水偏多 ,尤其是浙北杭嘉湖地区降水异常多 ,造成大范围的洪涝灾害 ;全省季日照时数明显偏少 .持续低温多雨寡照 。
The study of climatic characteristics during the summer of 1999 in Zhejiang Province shows that:(1)the mean seasonal temperature is distinctly lower than normal,especially in some regions where historical record lows were broken;(2)the number of days with the maximum temperature of 35℃ was also obviously lower than normal.This indicates that the summer of 1999 was a cold summer.During Meiyu period,precipitation was heavier than normal,causing severe flood disater in Northern Zhejiang Province.The weather,with low temperatures,prolonged rains and little sunshine severely influenced the crop growth.
