摘要
在原“北半球经纬度格点客观分析方法”。(1981)工作的基础上,引进了卫星测风,飞机观测,浮标站观测,船舶地面观测等非常规观测资料,进行分析试验。并增加了1000hPa高度场和温度场的分析及四层湿度场的分析。并且对非常规观测资料在分析质量中的作用进行了试验。试验表明,上述几种非常规观测资料对客观分析要素场的质量提高有重要的作用,特别是对常规观测资料稀少的大西洋和太平洋地区的客观分析的质量有明显的提高。
Based on the objective analysis scheme of the grid points of longitude and latitude, some ex-periments of incorporating unconventional data of satellite wind, reconnaissance aircraft, buoysand surface ship reports have been made. The pressure and temperature fields at 1000 hPa andmoisture at four levels have also been analyzed. The analysis quality of this scheme has been ex-amined. The results show that the incorporation of above-mentioned unconventional data is veryimportant for the improving analysis quality. Especially for the Pacific and Atlantic areas wherethe conventional data are relatively sparse, the objective analysis is significantly improved.
