Taking the mean values for the season.s we have — 



Table 42. 

 Mean Monthly Departures of Tempe.ratxire from Average in McMurdo Sound. 



From the above table we see that the mean variability is twice as great in the winter 

 as in the summer. 



In order to compare the above values with those for other places the following data 

 are taken from Hann's Meteorologie, 3rd edition, page IIU : — 



Table 43. 

 Mean Monthly Departure of Temperature from Average. 



The monthly variations in MciMurdo (Sound, as far as can be judged from five years' 

 observations, are in both summer and winter less than in Russia. In the winter they are 

 greater than in Italy and England, but of about the same value in the summer. On the 

 mean of the year the monthly variations in McMnrdo Sound are less than in Russia, but 

 greater than in England, Italy or Germany.
