| 摘 要： | 认识渤海海冰冰厚热力增长特征,是开发利用海冰资源的理论基础.本文通过2005年1月12日-27日在辽东湾鲅鱼圈和渤海湾黄骅海冰现场实验个例研究得出:鲅鱼圈的累积冰厚平均日增量1.33 em/d,平均冰厚日变化为3 cm;黄骅的累计冰厚平均日增量为0.54 cm/d,平均冰厚变化22.3 cm;冰厚从0 cm增长到10 cm所需的时间为鲅鱼圈5 d左右,黄骅10 d左右;冰厚日变化与日平均气温和日平均冰温与之间相关性显著,但冰厚对气温和冰温降低的反应有一定的滞后性;当环境温度持续下降时,累积冰厚与累积气温之间有显著的正相关,当环境温度上升时,累积冰厚与累积气温之间相关性逆转.

| Abstract: | To make full use of the amount of sea ice resources,it is a basic understanding of the characteristics of the thermal growth of sea-ice thickness.In this paper,an observation in Huanghua of Bohai bay and Bayu circle of Liaodong bay was performed to study the characteristics of the thermal growth of sea-ice thickness.The conclusions of this study are as follows:Average daily increase amount of accumulated ice thickness and ice thickness at Bayu circle is 1.33 cm,3 cm respectively.Average daily increase amoun... |
