对西南极半岛乔治六世海峡（WAP） Fossil Bluff长期地表气温记录的分析，首次详细记录了该地区气候的一些重要方面。分析表明，WAP地区的气温与纬度密切相关，但这种相关性在冬季最强。这一结果以及其他结果导致化石崖气候体系被描述为“大陆性”，而不是更北的“海洋性”。WAP整体表现出较大的年际温度变化，但这种变化在玛格丽特湾最大，而不是化石崖地区。还提供了过去几十年在整个WAP夏季出现的长期气候变化的证据。还注意到主要基于雪温测量的现有南极半岛年气温气候学在冬季和夏季期间的代表性。
An analysis of a long-term surface air temperature record for Fossil Bluff in the George VI Sound, West Antarctic Peninsula (WAP) documents in detail some important aspects of the climate of this area for the first time. The analysis identifies the close dependency of air temperatures on latitude in the WAP but reveals that the strength of this dependency is greatest in winter. This result along with others leads to the Fossil Bluff climate regime being characterized as ‘continental’ rather than ‘maritime’ as found further north. The WAP as a whole displays large interannual temperature variability but this is greatest in Marguerite Bay rather than the Fossil Bluff area. Evidence is also provided for secular climatic change appearing in summer throughout the WAP over the last few decades. The representativeness of existing Antarctic Peninsula annual air temperature climatologies, based mainly on snow temperature measurements, for the winter and summer periods is also noted.
