| 摘 要： | 统计分析上世纪50年代—2010年渤海及黄海北部海冰资料,对其年代际变化特征进行分析。上世纪50年代—90年代冰情总体呈缓解的趋势,2000年以来冰情略有加重。研究发现太阳活动与渤海及黄海北部冰情变化关系密切,太阳活动可能是渤海及黄海北部冰情长期变化重要影响因素。如果太阳黑子的周期长度比上一个周期长,那么周期内冰情较上一个周期严重。反之亦然。

| Abstract: | It is shown that the solar activities potentially exert significant influence on the intensity of sea ice in the Bohai Sea and the northern Yellow Sea.Based on the data sets from 1950—2010,the interannual variability of the sea ice is analyzed in the Bohai Sea and the northern Yellow Sea.The intensity of sea ice was decreasing from the 1950s to 1990s,while it has been intensified since 2000.The influence of solar activity to the sea ice was studied.It is shown that the solar activities potentially exert significant influence on the intensity of sea ice in the Bohai Sea and the northern Yellow Sea.The sea ice tends to be intensified compared to that in the last cy-cle if the sunspot period is longer,and vice versa. |
