摘要：

本文给出了一个改进后的海冰热力模式,主要通过海面和冰面的温度变化及热量收支,用来计算海冰面积和厚度的时空分布。取北极区大气和有关场的气候资料,由该模式模拟了北极海冰空间分布和季节变化循环特征。模拟结果与部分研究工作,以及实况相比较,基本状况近于一致。这为进一步建立冰气耦合特征模式,探讨冰-气耦合相互作用,提供了较好的基础。

In this paper,a Sea ice thermodynamics model is improved,for computing the distribution and temporal variation of Sea ice thikness and compatness by using temperture data on the sea surface and ice surface as well as thermal budget.The characters in the distribution and Seasonal cycle of arctic Sea ice are Simulated by this model using some climate data at arctic region.The simulating results are more agree with the some of Observation and part of research works.It will be provide a good condition to futher construct air-sea ice coupling characteristics model for exploring air-sea ice interaction.
