中文摘要: 北极地区风观测资料较少,工程气象参数的分析主要依靠国际交换站资料。但是,国际交换站资料为定时资料,并且存在较多质量问题。因此,在利用国际交换站资料时,需先对其进行质量控制,并且要考虑定时资料的转换。由于缺少其他参考资料,国际交换站资料的质量控制主要根据北极地区天气气候特征,通过时间一致性、空间一致性和要素间一致性检验进行。由于重现期风速需用年最大风速(通常是10 min平均风速)计算,鉴于定时资料中可能没有出现年最大风速,而目前又没有较好的定时资料向逐时资料转换的方法,因此,主要通过从定时资料统计得到的年最大值计算的重现期风速进行订正得到重现期风速。订正的方法是根据我国部分风速较大地区的观测结果,引入风速方差,建立定时资料与年最大风速资料计算的重现期风速之间的关系,然后利用此关系订正北极喀拉海和拉普捷夫海沿岸定时资料计算的重现期风速,得到了50年和100年一遇的风速。
Abstract:The data of international exchange stations are an important basis for studying engineering meteorological parameters in the area of only few observational data. However, this data are timed data which have some quality problems. Therefore, quality control of the data and the transform of timed data are necessary before further study. Being to lack of other references, the quality control of the data includes temporal consistency check, spatial consistency check and consistency check between various observed elements based on the weather and climate characteristics of Arctic. Return period wind speed is calculated with yearly maximum wind speed (usually 10 min average wind) which may not occur in timed data. However, there is no any good ways to obtain hourly data from timed data, return period wind speed is therefore obtained mainly through correcting the return period wind speed calculated from timed data. By applying wind speed standard deviation, the relationship between return period wind speed calculated from timed data and yearly data is established, with which return period wind speed in Arctic is obtained.
