| 摘 要： | 利用全球预报系统GFS(Global Forecast System)数值预报资料对2012年11月21日西南地区高原机场一次地面阵性大风天气过程进行预报和分析。对比预报和实况,结果表明:GFS数值预报产品对云南地区高原机场的阵风发生区域、影响时段和持续时间有较好的预报效果;对藏区的拉萨和康定机场强阵风发生情况也有一定的预报效果;但对阵风的极大值有着不同程度的误差。

| Abstract: | Using global system GFS numerical prediction information, forecast and analyze the ground gust occured on November 21, 2012 in southwest plateau airport. Comparison between fore- cast and live, the results show that the GFS numerical forecast products have a good prediction on Yunnan area plateau airport gust area, impact time and duration; In Lhasa and Kangding airport the GFS also has certain prediction on strong wind conditions. But the prediction on wind data maximum has a different degree of error. Among them, the Yunnan region wind maximum forecast error is smaller, the Tibet region wind maximum forecast error is bigger. |
