英文摘要: Studies assessing air temperature variations and their dependence on altitude from the eastern side of the Antarctic Peninsula are sparse. In this paper, we analyse air temperature and near-surface lapse rates from the Ulu Peninsula (James Ross Island, Antarctic Peninsula). The temperature data were acquired from nine sites both in ice-free areas and glaciers of the Ulu Peninsula in 2013–2016. The most important factors influencing air temperature differences were sea-ice conditions, topography and ground surface properties. During the study period, air temperature decreased with height with the mean lapse rate of 0.40 °C 100 m −1 for the ice-free sites (10–375 m a.s.l.) and 0.43 °C 100 m −1 for the glaciated sites (268–539 m a.s.l.). However, the values were lower in winter (ice-free: 0.02 °C 100 m −1 and glacier: 0.31 °C 100 m −1 ) than in summer (ice-free: 0.62 °C 100 m −1 and glacier: 0.51 °C 100 m −1 ) for both categories. The air layer between 10 and 56 m a.s.l. in the ice-free area revealed an almost year-round air temperature inversion resulting in a mean lapse rate of −0.79 °C 100 m −1 and an air temperature inversion frequency reaching up to 43%. The temperature inversion frequency was 10% lower for the lowest air layer for the glacier category, which was between 268 and 356 m a.s.l. The land surface air temperature was the highest when the wind was from the northwest and lowest when it was from the south–southwest. The near-surface lapse rate–wind direction relationship was the most pronounced for the air layer between 10 and 56 m a.s.l. with the lowest mean lapse rate for west–southwest wind (−2.83 °C 100 m −1 ) and the highest for east–northeast wind (0.41 °C 100 m −1 ). © 2018 Royal Meteorological Society Citation statistics:
