影响探空气球探测高度的因素分析

摘要

本文从气球的储存、气球的充灌使用、净举力的调整、升速控制、氢气的纯度、天气状况等方面，对影响探测高度的因素逐一进行合理分析，总结归纳出提高施放高度的有效途径，并利用本站2001～2011年探测高度资料进行统计比较，结果表明：随着各项措施的采用，特别是净举力的调整及球皮的更新，探测高度大幅度提高，为天气预报和气候分析提供了更多的可用气象信息和资料。%This paper reasonable analyses factors impacted on sounding altitude from the following aspects of balloon storage, balloon filling, net lift force adjustment, acceleration control, hydrogen purity and weather condition. The effective ways to improve releasing balloon height are summarized, and the sounding altitude data observed from the year of 2001 to 2011 are compared. The results show that with the adoption of each measure,in particular,by means of net lift force adjustment and ball skin update, sounding altitude increases in a great degree, which provide more available weather information for weather forecast and climate analysis.
