FIGURE II ANNUAL AMPLITUDE OF MEAN MONTHLY SEA SURFACE TEMPERATURE 

 IN THE NORTH ATLANTIC (°F) 



this point, the mean annual surface temperature ( 0s a ) in the lower 

 left graph is intersected. Vertically "below this point is the predicted 

 mean temperature at UOO feet, ^^qq . For example, given latitude 35°N, 

 15 May, annual surface_ amplitude of 7.0°F, and mean annual surface tem- 

 perature of 70.0°F, ^400, is 62.0°^. 



A prohlem arises in choice of an equation and its corresponding 

 nomogram. This is not an easy prohlem in many cases. The approximate 

 areas and boundaries of the h equations are shown in figure 12. The 

 "boundaries are based partly on test res\d.ts and partly on the isopleths 

 which represent zonal temperature anomaly distribution for August. 



The zonal temperature anomaly for a given location is the difference 

 between the mean monthly temperature for that location and the mean monthly 

 temperature computed with all data collected in the ocean along the latitude
