The impact of NOAA 9/10 satellite sounding data (at December 1987) has been assessed by both changes in S1 skill score and root mean square (RMS) errors for 24 and 48 hour forecasts of sea level pressure (SLP) and 500hpa height.

• 本文用均方根误差(RMS)和S1记分评价NOAA9/10气象卫星1987年12月探测数据对B-模式分析预报系统的影响(效果)；得出:1.；卫星数据和常规数据等权同化分析预报；陆地和海洋上的海平面气压(SLP)48小时预报的RMS减小(正影响)达到11
