Analysis of meteorological factors influencing aviation flight at Zhongshan Ice and Snow Airport in East Antarctica
摘要
Abstract
Using observation data from 2000-2019,this study analyzes the characteristics of meteorological el-ements near the Zhongshan Ice and Snow Airport,East Antarctica.These data are combined with captain reports from"Snow Eagle 601"to determine the multi-time scale characteristics of days with visibility of<5 km,days with runway crosswinds of≥6 force level,and days meeting the flight conditions.There are significant seasonal differences in the statistical relationships between the meteorological elements.The visibility at the airport is generally good,but there are more cloudy days,with only 13%～37.6%of the days being sunny each month.On average,there are 2～3 and 2～5 days each month with low visibility and runway crosswinds,respectively,and the number of flyable days is higher in December and January,with an average of about 8 d.The low visibility is typically caused by the presence of a circumpolar cyclone in the north and a weak anticyclone in the south,leading to the convergence of cold and warm air at the airport.Southeast-ward and easterly runway crosswinds correspond to extreme katabatic winds and cyclonic gales,respectively.In summer,when the polar high pressure is weak,there are more days with low visibility;however,the fly-ing conditions are better.关键词
