the same sense as does advection, it is 

 impossible to deduce from these data whether 

 their effects are substantial, ^^onetheless, 

 the mechanisms underlying observed corre- 

 lations between wind indices and sea surface 

 temperature should not be wholly categorized 

 as advection. 



These examples indicate some types of 

 associations which may exist between atmos- 

 pheric circulation, ocean conditions and 

 fisheries. They are mere suggestions, how- 

 ever, requiring more thorough understanding 

 of processes and more rigorous treatment 

 to gain the stature of conclusions. It is 

 hoped that the data given herewith will 

 stimulate and aid further studies of more 

 definitive quality. 



Specifically this characterization of 

 monthly mean sea level pressure patterns by 

 numerical indices facilitates the quantita- 

 tive comparison of circulation anomalies 

 at different times and in different repre- 

 sentative regions. Monthly anomalies Eire 

 generally greatest in winter and, as sug- 

 gested by the correlation study with Triple 

 Island temperatures, may produce effects 

 which persist locally for several months. 

 The amomalies are also generally larger in 

 some regions than in others, and it might 

 be expected that the largest effects in the 

 ocean are produced in regions of greatest 

 wind anomalies. Since the oceaxi is a con- 

 tinuous fluid body, events occurring in one 

 region may be transmitted by advection or 

 dynamic readjustment to other regions. 

 Thus the explanation of oceanographic 

 fluctuations observed in one region may lie 

 wholly outside that region.
