嫦娥五号飞行试验器发射日雷雨天气过程气象保障分析

Analysis of Meteorological Support to the Launch of Chang'e-5 Orbiter during a Thunderstorm Process

简要介绍了嫦娥五号飞行试验器发射日对任务进程有重大影响的射前8小时雷雨天气的保障,对该雷雨天气过程的降水、雷暴预报和物理量进行详细分析。结果表明,发射窗口天气预报准确、及时、可靠,为发射任务成功实施提供了重要决策依据,是一次成功的航天气象保障个例,可为后续高密度航天试验任务气象保障提供借鉴。

The 8-hour meteorological support before the launch of Chang＇e-5 orbiter during a thunderstorm process is introduced briefly. However, the rainfall variability, thunderstorm forecast and some other physical variables are analyzed in detail. The results show that： the weather forecast for the launch window is accurate, timely and reliable. This weather forecast is a successful meteorological support for space activities, and also provide a basis for the decision-making in the successful launch of Chang＇e-5 orbiter. According to the above results, it will provide reference for the meteorological support for the forthcoming high density space activities.
