Figure 10. — Variation in minimum observed temperature of the Labrador Current in the Grand Banks 

 region during the 1941 season compared with mean variation, 1934-41. 



the minimum observed temperature of the Labrador (\u-rent in the 

 Grand Banks region at sections T, U, and W during 1941 and the mean 

 variation for the period 1934-41. It is apparent that in 1941 the mini- 

 mum observed temperatures were abnormally warm. Also, it is con- 

 sidered probable that the 8-year mean minimum observed temperature 

 is warmer than the normal. The accumulated data are too meager to 

 draw many conclusions regarding the seasonal cycle, but figure 10 

 seems to indicate a drop in minimum temperature from April to May 

 at sections T and U. This drop, if really a part of the seasonal cycle, is 

 probably associated with the seasonal increase in volume of flow which 

 is considered to reach a maximum normally in May, and which has 

 been considered to be related to the normal wintertime maximum in 

 the barometric pressure gradient across the Labrador Sea. The southern- 

 most section, W. is probably more affected by other modifying factors, 

 such as fluctuations in the North Atlantic eddy, than are the more 

 northern sections, T and U.
