烟台北部面临黄、渤海,海岛自动站分布众多。我们发现,在同一大风过程中,各海岛自动站的风速、风向因为海拔高度、周围地形影响、下垫面摩擦的不同造成明显差异。本文主要以长岛作为渤海海峡大风的代表站,以崆峒岛和芝罘岛作为烟台北部沿海海域大风的代表站,利用便携自动站的观测数据近似代表海面大风的实况,与代表站进行大风的对比试验,对比试验的数据均采用指数廓线公式订正到海面10 m高度。分析了三个海岛自动站的不同风向下的海面大风的实际代表性,并给出不同风向下的大风订正值。 |
The north of Yantai is adjacent to the Yellow Sea and the Bohai Sea. During the same strong wind process, we find that wind speeds and wind directions on different islands have different characteristics, which are resulted from the differences in altitude, geography and surface friction. In this paper, wind observation data, derived from Changdao automatic weather station representing Bohai Strait's gale station and from Kongdong island and Zhifu island representing of the northern coast of Yantai, are selected and compared with the data from portable automatic weather stations. The data for the contrast test are all corrected to 10m above sea level using the exponential profile formula. Representations of sea wind in different directions are analyzed and correction values are derived from the three islands wind observations. |
