Název v původním jazyce

The effect of wind direction on air temperature variability on James Ross Island

Popis výsledku v původním jazyce

The western and eastern parts of the Antarctic Peninsula are quite different, especially due to frequent atmospheric blocking or foehn events induced by the mountains. In order to study the influence of topographic modification on atmospheric circulation and its impact on cryosphere, the air temperature measurements from the northern part of James Ross Island were evaluated with respect to surface wind direction. Meteorological parameters from 2013-2016 were observed in one-hour interval by multiple automatic weather stations, while 1000-hPa pressure level data from the ERA-Interim reanalysis were used to assess the surface wind effect. Furthermore, near-surface temperature lapse rates were calculated and linked to boundary layer processes. The results were analysed with respect to topographic conditions, separately for ice-free parts and glaciers of the Ulu Peninsula. The seasonal and inter-annual variation of the selected near-surface atmospheric variables was emphasized in the study.
