摘 要:基于1979—2021年的气象再分析数据,本文研究了南极洲的近地面气象要素满足航空起降要求的概率分布(即可起降率的变化)。结果表明,南极洲飞机可起降率具有显著的季节性和空间差异等时空变化特征:西南极飞机可起降率总是高于东南极高原区域,如西南极的夏季可起降率气候态平均高达57.0%,而东南极的高原区域只达到49.4%;夏季最高,然后依次为春季、秋季和冬季。从长期变化趋势角度来看,夏季大部分内陆地区飞机的可起降率呈现显著降低趋势,多数沿海地区可起降率呈上升趋势;在春季,大部分高原地区和威德尔海内侧地区等飞机可起降率也呈现显著上升趋势。在考虑日照时间的前提下,各个子区域的大部分季节里近地面风速、温度和能见度的影响各异。沿海地区飞机可起降率更易受风速影响,高纬地区(包括东南极高原和整个西南极)更易受降雨(含降雪)情况控制的能见度影响。此外,南极几个主要冰架区域升温严重,因此,在机场选址时还应考虑冰架或内部冰盖崩塌的潜在威胁。Based on meteorological reanalysis data obtained during 1979—2021,this study evaluated the probability distribution of near-surface meteorological elements in Antarctica to meet the requirements of aviation take-off and landing(i.e.,the change in take-off and landing rate;TLR).Results showed that the aircraft TLR has substantial spatiotemporal variability over the Antarctic continent.In West Antarctica,the TLR is always higher than that in East Antarctica Plateau region.For example,the climatological average summer TLR in West Antarctica reaches a maximum of 57.0%,while that in East Antarctica reaches only 49.4%in the plateau areas.The TLR is highest in summer,followed in descending order by that in spring,autumn,and winter.From the perspective of the long-term trend,the TLR in most inland areas in summer has a notable decreasing trend,while that in most coastal areas has an increasing trend.In spring,the TLR in most plateau areas and the inner area of the Weddell Sea has a strong upward trend.When sunshine hours are considered,the effects of near-surface wind speed,temperature,and visibility vary in most seasons in each sub-region.Coastal areas are more susceptible to wind speed,while high-latitude areas(including the East Antarctic Plateau and the entire area of West Antarctica)are more susceptible to visibility controlled by precipitation.Additionally,several major Antarctic ice shelf areas are experiencing severe warming,and the potential impact of ice shelf or internal ice sheet collapse should be considered when selecting an airport location.
