The title of the Project : The Mechanism of Air-Sea Interactions in the Marginal Ice Zone and the Dynamics of Drift Ice.In this project period (1989-1991), the influences of sea ice on the air-sea interaction in the arctic oceans and marginal ice zone, the relationship between the ice concentration and air temperature, and a method to estimate the roughness of ice su13EA\ : rface, i.e., the drag coefficient with a X-band radar were studied.The results may be summarized as follows :1. The influences of sea ice on the mechanism of an air-sea interaction.The coefficients of momentum and heat fluxes obtained in ice covered sea under various ice conditions.2. Relationship between the air temperature and ice concentration along the Okhotsk Sea coast of Hokkaido.The relationship between the accumulated ice concentration, which is defined as the summation of the daily ice concentration in a winter, and air temperature along the Okhotsk Sea coast of Hokkaido were statistically investigated. The result suggest13EA\ : s the effect of the global warming, which is expected to become significant in the 21st century, on the decrease of sea ice area in the marginal ice zone.3. Definition of an aerodynamical roughness of the sea ice surface with the X-band radar.It was shown that the variance of the signal intensity of back-scatter echoes of a X-band radar related to the aerodynamic roughness, i.e., the drag coefficient.

项目的标题：边际冰区的气海相互作用的机制和漂流冰的动态。在这个项目时期（1989-1991），海冰对北极海洋和边际冰区的空气相互作用的影响，冰块浓度和空气温度之间的关系，以及一种估算冰uce su13ea co13EA的方法。研究了结果。结果可以总结如下：1。海冰对空气相互作用机制的影响。在各种冰条件下，在冰覆盖的海中获得的动量和热通量的系数。2。沿北海道的Okhotsk Sea海岸的空气温度与冰浓度之间的关系。累积的冰浓度之间的关系定义为冬季的每日冰浓度的总和，以及沿海北海道海岸的空气温度在统计上进行了研究。结果表明13ea \：s全球变暖的影响，预计在21世纪将变得很重要，对边际冰区海冰地区的减少3。海冰表面带有X波段雷达的空气动力学粗糙度的定义。这表明，X波段雷达的后刻板信号强度的差异与空气动力学粗糙度有关，即阻力系数。
