【摘要】 应用干旱风沙区甘肃省民勤2004-2016年逐日24时次地面风场、08时和20时9层规定层高度高空风场以及每隔50 m加密高空风场资料,逐日24时次低云量、能见度资料,1961-2016年日最低气温资料,详细分析总结了民勤地区飞行气象条件,以及主要影响飞行的天气要素时间变化特征,如雷暴、低云量、能见度和沙暴等。得出民勤地区的盛行风向为NW-SE方向,一年中的夏秋季和一天中的上午,气象条件适宜飞行,从而对民勤小型机场建设及开展低空飞行提供良好的气象服务。更多还原

【Abstract】 Using daily 24 times’ ground wind data, 9 layer high altitude wind field and every 50 meters encryption high altitude wind field data at 08 h and 20 h, daily 24 times’ low cloud amounts, minimum visibility in arid sandy area of Gansu Minqin during 2004-2016, daily minimum temperature data during 1961-2016, the flight meteorological conditions in Minqin area, main weather elements’ time variation characteristics of effecting flight, such as thunderstorms, low cloud, visibility and sandstorm etc have been analyzed and summarized in detail. It is shown that the prevailing wind direction in Minqin area is NW-SE. During the summer and autumn of the year, morning of the day,the meteorological conditions are suitable for flight, in order to provide good meteorological services for the small airport construction and low altitude flight of Minqin.更多还原
