苏尼尔水文站气象要素对比分析

根据苏尼尔水文站新气象站与原气象站2007年10月—2008年9月的气温、降水量、水面蒸发量等同期观测资料,分析了各气象要素随位置及地形的变化特征。结果表明,气温随高度升高而降低,降水量随高度升高而增大;新气象站位于苏尼尔河出山口,受地形因素影响,风速相对较大,大风出现频次高,蒸发量较大,大多数月份没有出现蒸发量随高度升高而减小的变化趋势。

Contrastive Analysis of Meteorological Elements Observed from the Sunier Hydrologic Station

According to the observed data, such as temperature, precipitation, water surface transpiration rate, from the new observation field and original field of Sunier hydrologic station from Oct. 2007 to Sept. 2008, this paper analyzed the variation characteristics of various meteorological elements along with the position and the terrain. The result indicated that: contrary to precipitation, the air temperature reduces along with the elevation increase; the new observation field is located at mountain-pass of Sunier River and influenced by the topographic factor, the local wind speed was relatively large, the gale frequency was high and the transpiration rate was big, and while the transpiration rates did not decrease with the increasing elevation in major months.
