A THREE-LAYER OCEAN CIRCULATION MODEL APPLICATION TO NUMERICAL STUDIES ON THE NORTH PACIFIC OCEAN CIRCULATION

The formulation and justification of a three-layer baroclinic ocean model developed to simulate thegeneral circulation of the ocean are described in this paper.Test of the model in simulating the annualmean circulation patterns in the North Pacific under the prescribed atmospheric forcing,which consists ofthe climatological surface wind stress and sea surface heat flux,and comparison of the results withobservations showed that the model basically simulated the large scale features of the annual meancirculation patterns in the North Pacific Ocean such as those of the intensified western boundary currentsand the North Equatorial Currents and Undercurrents.But due to the coarse resolution of the model,some details of these currents were poorly reproduced.The seasonal variations of the North Pacific Oceancirculation driven by the seasonal mean sea surface wind stress was calculated,the different aspects of theseresults were analyzed and the main current(the intensified western boundary currents)transports we     

航空遥感在河口和海涂资源综合调查中的应用

本文根据1980年珠江口磨刀门河口航空遥感所提供的多光谱扫描图象和该区域海涂资源的分类设计方案、程序,应用IPOS/101数字图象处理系统进行图象增强、分类处理,得到分类图件,对珠江口磨刀门河口海涂、水下地形进行解译探索。同时根据实地踏勘,室内解译,将所得分类图件进行实地验证,其精度达86.2％,这就可直接为磨刀门河口工程提供直观、可靠的依据,并且,比常规方法节省人力、物力和财力。
