通过分类统计岳阳各气象观测站1994—2013年不同天空状况、不同风类以及天空状况与风类结合的逐月最低气温数值差异，总结归纳了不同类型条件下岳阳各气象观测站逐月最低气温差异分布规律。结果表明：晴天时平江、临湘站最低气温比岳阳低4~6益、2~4益；东南风时平江、临湘站最低气温比岳阳低3~5益、1~3益；在月际分布中，2、3、4、11、12月晴天下东南风时平江站最低气温均比岳阳低6益以上；而差异较小的阴天或西北、东北风时全市最低气温差异均在1益或以下。分析的结果为全市最低气温日常预报工作提供了客观、定量的预报依据。
通過分類統計嶽暘各氣象觀測站1994—2013年不同天空狀況、不同風類以及天空狀況與風類結閤的逐月最低氣溫數值差異，總結歸納瞭不同類型條件下嶽暘各氣象觀測站逐月最低氣溫差異分佈規律。結果錶明：晴天時平江、臨湘站最低氣溫比嶽暘低4~6益、2~4益；東南風時平江、臨湘站最低氣溫比嶽暘低3~5益、1~3益；在月際分佈中，2、3、4、11、12月晴天下東南風時平江站最低氣溫均比嶽暘低6益以上；而差異較小的陰天或西北、東北風時全市最低氣溫差異均在1益或以下。分析的結果為全市最低氣溫日常預報工作提供瞭客觀、定量的預報依據。

Through the classification statistics with the data from 1994 to 2013 from the Yueyang meteorological stations, the distribution of monthly minimum temperature differences under the different weather conditions was summarized. The results show as follows. When it was sunny, the minimum temperature at Pingjiang and Linxiang Railway Station was 4~6℃and 2~4 ℃lower than that at Yueyang. When the wind came from the southeast, the minimum temperature at Pingjiang and Linxiang Railway Station was 3~5 ℃ and 1~3 ℃ lower than that at Yueyang. About the inter-monthly distribution, when sunny days with wind from the southeast in February, March, April, November and December, the minimum temperature at Pingjiang was more than 6 ℃ lower than that in Yueyang and smaller differences such as 1 ℃ or less in cloudy days with wind from the northwest. The analysis results provide objective basis for quantitatively forecasting the daily minimum temperature.
