摘要
随着东营沿海5座测风塔站的建立,新的观测数据融入到预报业务中。利用2010—2011年测风塔与沿海自动站资料,统计分析了东营沿海大风的特点,并将两者资料进行对比分析,得出了如下结论:(1)东营沿海大风过程北部多于东部,冬、春季明显多于夏、秋季,其中4月最多,8月最少。大风的主导风向是西北和东北,约占全年大风过程风向频率的80.5%;(2)在自动站与测风塔的对比分析中,当有一方风力达到6级或以上标准时,另一方风力会随之调整,并有四种变化模式与前者相适应;(3)以自动站与测风塔之间的变化模式为基础,探讨了东营沿海大风的风向、风速及其持续时间等方面的预报着眼点。
With the establishment of coastal Dongying 5 wind tower,the new observed data is added into the weather forecast.Using the data of wind tower and the coastal automatic stations from 2010 to 2011,the characteristic of Dongying coastal winds is analyzed.Through the comparison and analysis of the data,we draw the following conclusion：（1） windy weather in the northern coast of Dongying is more than that in the East,and windy weather times in winter and spring are significantly more than that in summer and autumn,especially most in April,least in August.The prevailing wind is NW-NE,about 80.5％ of the total wind direction frequency.（2） Under comparing the Automatic station with tower,when the wind reaches level 6 or above standard,the other side wind also will be adjusted,and there are four patterns of variation according the former adaptation.（3） Finally,based on the change models between wind tower and the coastal automatic station,the forecast of Dongying coast gale wind,wind direction,wind speed and duration of wind was discussed.
