中国南极新站选择在维多利亚地特拉诺瓦湾难言岛上进行建设，其气象环境状况是开展科学研究的基础工作，也是考察队员生命安全保障的基础资料。因此，通过2013年度难言岛气象站的观测资料，结合附近地区历史气象资料，对该区域气象要素特征进行了分析。结果表明：（1）由于地处罗斯海与东南极冰盖交界处，难言岛年均气压为987．8 hPa，与中山站非常接近；（2）年均温为－16．1℃，最低气温为－39．3℃，且冬季气温波动较大，标准差可达±6．0℃；（3）年均相对湿度为42．1％，年均比湿为0．6 g· kg－1且冬季比湿极低，空气非常干燥，降水量非常低；（4）盛行风向为WNW，5—7级风出现频率超过50％，但夏季风速明显低于冬季风速，一般不超过8．0 m· s－1，有利于中国在夏季开展工程建设和补给；（5）难言岛年总辐射量为3342．8 MJ· m－2，明显低于中山站，但两站反照率非常接近。

In the 2012/2013 austral summer, the 29th Chinese National Antarctic Research Expedition deployed an automatic weather station to collect information of meteorological characteristics of Inexpressible Island . This information was required to determine whether the location would be suitable for a new Antarctic station .Over the past year , parameters such as air pressure , air temperature , relative humidity , wind speed and direction , solar radiation have been recorded .Based on these data and historical data collected by the United States and Italy , climate conditions were evaluated to provide basic environmental information for future research , and to ensure the safety of future field expeditioners .The annual mean air pressure in Inexpressible Island is 987.8 hPa, similar to that at Zhongshan Station , and the annual mean air temperature is -16.1 ℃with a minimum of -39.3 ℃.An-nual mean relative humidity is 42.1%and specific humidity is only 0.6 g· kg-1, which implies low precipitation. The prevailing wind is west-northwest and the wind speed is greater than 8 m· s-1 during most of the year .Howev-er, the wind speed tends to drop during summer ,which is beneficial for resupply and icebreaker-based research. The global radiation at Inexpressible Island is 3342.8 MJ· m-2 , which is less than that at Zhongshan Station , but the albedo is similar at the two locations .
