摘要
对扎龙湿地生态气象站和齐齐哈尔自动气象站2004年6~8月的逐时气温、风速、相对湿度等观测资料进行统计分析,找出了不同下垫面的两站之间不同时次各气象要素的差异,指出两站风速、气温、露点温度、相对湿度、地面温度等的月平均值均存在差异,变化幅度及极值出现时间各有不同;下垫面差异只起到加强或缓和气象要素日变化幅度的作用.所得结果有助于深入了解扎龙湿地的天气变化规律,对未来扎龙湿地气象要素的精细预报以及湿地资源的开发、保护和管理有一定的参考意义.
A detailed statistical analysis is made of the hour-to-hour temperature, wind speed, relative humidity data, etc, from the Zhalong wetland ecological meteorological station and Qiqihar meteorological automatic station from June to August 2004. The differences of the meteorological elements at different times between different underlying surfaces are found. The evidence shows that differences exist in the monthly mean wind speed, temperature, dew-point temperature, relative humidity, and surface temperature, and that the variation amplitude and the occurrence time of extreme values vary. The difference between different underlying surfaces only helps increase or decrease the daily variation amplitude of the elements. The findings contribute to the further understanding of weather variation regularities and are of referential significance in the fine forecasting of meteorological elements in the Zhalong wetland and the exploitation, conservation, and management of wetland resources in future.
