印江新建气象站风向风速代表性分析

Representative analysis of wind direction and wind speed of new meteorological stations in Yinjiang

利用印江县新建气象站24h自动观测风向风速资料和毗邻国家级台站及天气指标站相对应的资料对比分析得出:印江新站的风玫瑰图在西部区域代表性好,东部区域代表性较差,主导风向有随着测点东移主导风向逐渐偏东的趋势;山区风速随海拔增加而增加,主导风向上的平均风速总体较其他方位的风速偏大。

By comparing and analyzing the 24-hour observation data of wind direction and wind speed of the newly-built meteorological station in Yinjiang county and based on the data of the adjacent national stations and weather indicator stations,it is concluded that: wind roses of the new station in Yinjiang are well represented in the western region,while the eastern region is poorly represented. The dominant wind direction has a tendency of gradually shifting to the east as the measuring point moves eastward. the mountain wind speed increases with the increase of altitude,and the average wind speed in the dominant wind direction is generally larger than that in other directions.
