was not present in the previous case. Since Stommel's paper 

 all problems dealing with general circulation contain a varying 

 Coriolis parameter, Munk [^] refined all the previous work and 

 included the general viscous terms in the equations of motion* 

 He solved the problem of a steady wind blowing over an enclosed 

 ocean, taking account of many of the salient features which are 

 present in the real ocean, Munk's work was extended by Munk 

 and Carrier [ 6 ] to include oceans of various geometrical shapes, 

 viz. , triangular and semi-circular. It was further extended 

 by Munk, Groves, and Carrier [7] to include the non-linear terms 

 by means of a perturbation procedure. 



Along with the American publications, a number of papers 

 have appeared in Japan. Notable among the Japanese authors is 

 Hidaka, who published a series of articles covering many of the 

 interesting phenomena of oceanographic problems. Among his con- 

 tributions are a series of three papers on drift currents in an 

 enclosed ocean [12], [I3] , [!*+], and a contribution concerning 

 the neglect of the non-linear terms in the solution of problems 

 in dynamic oceanography [l5]t 



Practically all of the work done so far in ocean current 

 problems has been confined to motions which are independent of 

 time. Each publication has treated some aspect of the general 

 problem of oceanic circulation. This problem essentially con- 

 sists of finding the dynamic pattern which results from a given 

 distribution of v;inds acting on the ocean surface. 



The complete problem contains a large number of features, 

 such as large-scale oceanic circulation, surface waves,upwelling,
