摘　　要：为弥补海洋、高原等地带常规资料的不足，分析使用非常规卫星资料得到越来越多的重视，其中TOVS资料的精度及与常规资料的误差减少的研究尤为重要。本文采用变分分析技术对TOVS卫星反演资料进行同化分析研究，结果表明，变分结果分析场能充分体现常规与非常规资料的优势，使得天气系统能得到更精确的表示。In order to make up the short of regu1ar data in ocean、highland and so on, people pay more and more attention to analysing and using irregular data-satellite information. To study the accuracy of TOVS data and to reduce the difference between TOVS data and regular data become especially important. We analysed and studied TOVS satellite retrieval data with calculus of variations. The result fields showed the both advantages of regular and irregular data, They could indicate weather system more exactly.
