利用近50年(1957～2006年)冬季盘锦大洼站的气温资料,对盘锦冬季平均最高、最低气温、平均气温及逐旬平均气温的演变进行了详细的分析.结果表明,盘锦冬季季平均气温年际变化呈上升趋势,不同年代呈现出不同的年代际变化特征;盘锦冬季平均最低气温上升是盘锦冬季气温升高的主要因子;冬季平均气温在整个研究时段中,除存在明显的4年左右的振荡周期和6～8年的周期外,还存在14～16的较长周期.并表现出不同年代的周期特征.%Using the winter temperature data at Dawa Station of Panjin during recent 50 years (1957 ～ 2006), the winter average maximum temperature, minimum temperature, average temperature and the evolution of average temperature and average temperature ten days by tem days in Panjin were analyzed in detail.The results showed that inter-annual changes of winter average temperature in Panjin was rising.Different years showed different characteristics of inter-decadal variations.The winter mean minimum temperature rise in Panjin was the main factor of winter warming in Panjin.The winter average temperature in the entire study period, except that there exists an obvious 4-year oscillation cycle and 6 ～ 8-year cycle, there's a longer 14 to 16 cycles.And different cycle characteristics of different years were demonstrated.
