WEATHER 



Throughout the season of the 1932 ice patrol the vessels actually on 

 patrol remained within 150 nautical miles of latitude 43° 00' N., and 

 longitude 50° 00' W. This position can be taken for all practical 

 purposes as the position where the observations which are described 

 below, month by month, were made. During April the vessels were 

 for the most of the time north of this position, and during May and 

 June to the south of it. As explained in the Bulletin for 1929, and 

 repeated here, too much stress should not be placed upon this posi- 

 tion, for the weather experienced by the ice-patrol vessels depended 

 to a great extent on their location in the ice-patrol area. The northern 

 part of the area cruised is often cold and foggy because of the Labrador 

 current water, while, at the same time, the near-by southern part is 

 warm and sunny because of the Gulf Stream influence. In comparing 

 figures of average air temperatures and fog percentages of any one 

 month with those of the corresponding month in previous years, or 

 of other months of the same year, the fact should not be lost sight of 

 that the warmer and clearer conditions recorded may be due not so 

 much to actually different conditions in the area as a whole as to 

 whether or not the patrol vessels were in the regions influenced by the 

 Gulf Stream or those influenced by the Labrador current. The track 

 of the ice-patrol vessels, giving the noon position each day, together 

 with surface isotherms for each cruise, are shown in Figures 1 to 6. 

 These charts should be studied in connection with the monthly 

 weather summary. 



The weather diagrams for each month that the patrol vessels 

 remained in the vicinity of the ice regions show graphically the wind 

 directions and forces averaged for each half-day period, the baro- 

 metric curve, and the time and duration of fog and poor visibility. 

 In addition the air temperatures and the percentage of time with fog 

 and poor visibility have been given for each patrol month. The 

 average air temperature for the month was obtained by averaging 

 the average of the hourly temperatures of the dry bulb for each day.
