| Abstract: | In this paper,the auto-observational surface wind data at Lijiang airport from 2013 to 2015 was used to analysis the variation of surface wind field statistically,and the influence of surface wind field to the flight was also summarized. The results show that Lijiang Airport prevailing southwest winds throughout the year with the maximum wind velocity and the Northeasterly wind is being of greater frequency which often resulting in excessive down wind. The dominant wind direction is southwest winds at daytime while it is northeast winds at night; the gale mainly occurred from 12 p.m to 18 p.m in January-April and there are 93% wind shear occurred in winter and spring. |
