| 摘 要： | 利用九黄机场20号跑道自动观测站2004-2010年8月和10月的2分钟平均风向和风速资料，对九黄机场8月和-10月风向、风速的半小时平均状况进行了统计分析。分析表明：九黄机场8月和10月风向分布总体差别不大，8月主导风向为ESE和SSW，10月主导风向为NNE和S；N和NNE风向日出现时间变化很大；风速日变化特征明显，夜间风速较小，白天风速较大；上午8：00左右风速开始逐渐增大，8月平均最大风速时间段为17：00．18：00，10月平均最大风速时间段为18：00．19：00，8月日半小时平均最大风速为5m·s^-1，10月日半小时平均最大风速为3．5m·s^-1；8月风速大于12m·s^-1几率较小，10月风速大于10m·s^-1几率较小，可为8月和10月九黄机场飞机起降提供有益参考。

| Abstract: | Based on the wind direction and average wind speed every 2 minutes in Aug. and Oct. from 2004-2010 at 20 automatic observation stations of huzhai-Huanglong airport, the wind characteris- tics are analyzed. The study shows that （1）-the wind direction is not very different. The main wind direction is ESE and SSW in August, and NNE and S in October. （2） N and NNE wind direction changes at times when wind velocity increases. （3） The characteristics of daily wind speed are similar in August and October, and the wind speed in daytime is stronger than that at night. The wind speed is getting stronger on 8：00 am. （4） The rate of gusty is seldom more than 12 m·s^-1 in August and 10 m·s^-1 in October. |
