摘要

利用遥感数据、大尺度动态-热力学数值海冰模型和半经验方法研究了拉普捷夫海冰漂移和与北冰洋冰交换的季节和年际变化。在1979-1995年期间，拉普捷夫海出口海冰，2月出口最多，8月出口最少。这一时期冬季平均冰流出量为482700 km/sup /。1936年至1996年期间拉普捷夫海南北冰交换的估计显示出强烈的年际变化，但没有显示出显著的趋势。

Studies of sea-ice motion in the Laptev Sea with the use of satellite remote sensing and numerical modelling

Seasonal and interannual variability of ice drift in the Laptev Sea and ice exchange with the Arctic Ocean have been investigated using remote sensing data, a large-scale dynamic-thermodynamic numerical sea ice model and semi-empirical method. During the period 1979-1995 sea ice was exported from the Laptev Sea with maximum export occuring in February and minimum in August. The average winter ice outflow during this period was equal to 482700 km/sup 2/. Estimates of ice exchange between the northern and southern parts of the Laptev Sea during the period 1936 to 1996 exhibited a strong interannual variability, but did not reveal significant trends.
