黄渤海海域16个石油平台站风速资料的初步质量检测

Preliminary quality verification of wind speed data observed by 16 oil platform monitoring stations in the Yellow Sea and Bohai Sea

对天津建设的16个石油平台站2017年2-10月的2 min平均风速和极大风速的逐时资料进行了质量检测。其方法包括气候学界限值检查、内部一致性检查、持续性检查、时间一致性检查、空间一致性检查以及质量控制综合分析。结果表明:有87.5%的石油平台站风速观测资料质量较好,能够为海洋气象预报、风能资源评估等提供宝贵的基础支撑。与此同时,由于石油平台上油烟较大、海上高湿、高盐等环境因素影响导致了12.5%的平台站风速资料质量较差,造成其大量时间段的资料不能被直接使用。从而,一定程度上说明了与地面观测资料一样,在使用海洋气象资料之前应进行系统的质量控制,只有清楚并解决海洋气象资料中存在的质量问题,才能保证业务应用、研究分析以及资料统计与加工的准确性和可靠性。

The quality of hourly 2-minutes mean wind speed and extreme wind speed from February to October 2017 of 16 monitoring stations installed on oil platform in the Yellow Sea and Bohai Sea is verified using climatic range check, internal consistency check, continuous check, time persistency check, spatial homogeneity check and quality control comprehensive analysis. The results show that the quality of 87.5% of the wind speed observations is reasonably well, which provide fundamental support for marine weather forecast and wind energy resource evaluation. However, the quality of the rest of the wind speed observations is relatively poor due to environmental affection including high fume, high humidity and high salt on the oil platform, which results in that the observation data can not be used directly for a large period of time. This study reveals that systematic quality control should be carried out before using the marine meteorological data. It is necessary to understand the problem of the observation data and to improve their quality to ensure the accuracy and reliability of their operational application, research and analysis as well as data statistics and processing.
