在鲅鱼圈港区工作码头港池内,风与海流对海冰的生成和成长影响较小,因此在此能生成典型的平整固定冰,结合近年来海冰力学性质测试研究,1986—1987年冬季,对该港区海冰的温度及其他物理特性进行了较系统的测试。本文以大量观测和测试结果为依据,介绍该港区平整固定冰的一般物理特征,重点分析日气温变化、长时间气温变化以及积雪对冰温的垂直分布的影响和一般变化规律,简述盐度、密度和晶体粒径的一般垂直分布规律。
In Bayuquan Pier harbor, wind and ocean currents have little effect on the formation and growth of sea ice. Therefore, a typical formation of fixed ice can be generated here. Combining with the test of sea ice mechanical properties in recent years, from 1986 to 1987 in winter, The temperature and other physical characteristics of sea ice in the harbor have been systematically tested. Based on a large number of observations and test results, this paper introduces the general physical characteristics of flat ice in Hong Kong, and analyzes the effects of daily temperature changes, long-term temperature changes and snow cover on the vertical distribution of ice temperatures. Salinity, density and crystal size of the general rule of vertical distribution.
