1979-2021年南极洲飞机可起降率的气候态及其年际变化趋势研究
Climatological distribution,interannual variation,and trend of aircraft take-off and landing rate in Antarctica(1979-2021)
摘要
Abstract
Based on meteorological reanalysis data obtained during 1979-2021,this study evaluated the prob-ability distribution of near-surface meteorological elements in Antarctica to meet the requirements of avia-tion 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 no-table 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 pre-cipitation.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.关键词
