龙海风压时空分布特征

利用龙海1959~2005年地面10 m in平均年最大风速资料,计算分析了历年地面最大风压的年际分布及同期内的极大风压的垂直分布,结果表明:离地面10 m高处的极大风压为49.0 kg/m2;50 m高处风压可增大到93.3 kg/m2;100 m高处风压可达到123.2 kg/m2,相当于44 m/s强风暴的破坏力。

Character of Wind Pressure Distribution of Longhai

Basing on ground yearly maximum ten-minute average wind speed observations during 1959~2005.We calculate interannual distribution of ground maximum wind pressure and vertical distribution of extreme wind pressure.The results indicate that ground extreme wind pressure is 49.0 kg/m~2 at 10 meters above ground;and wind pressure has reached 93.3 kg/m~2 at 50 meters above ground.Wind pressure is 123.2 kg/m~2 at 100 meters above ground,which has the same destructibility as 44 m/s strong storm.
