SCOTT'S LAST EXPEDITION 



between 5 and 9 miles per hour for 23 hours out of the hundred, 

 and velocities between 10 and 14 miles in the hour are met with 

 during 28-4 per cent, of the time. Higher velocities than these 

 occur less frequently, and during every hundred hours the wind 

 blows at a greater velocity than 45 miles only during three- 

 quarters of an hour. 



TABLE II. 



Frequency of Winds 



The figures in Table II. are plotted in Fig. i, in which the 

 thin line curve represents the data for Yarmouth. The curve 

 shows clearly how the wind at Yarmouth blows most frequently 

 with a velocity of about 10 miles an hour and that the frequency 

 of higher and lower velocities falls off very rapidly on either side 

 of the maximum. This curve is typical of all stations in the 

 British Isles. In every case investigated, calms are of infre- 

 quent occurrence, while there is some velocity which occurs most 

 frequently. The velocity which most frequently occurs varies 

 from station to station, being least about 5 miles an hour at 

 inland stations and greatest about 10 to 15 miles an hour at 

 coast stations. 



A similar analysis has been made of the winds at Framheim 

 the winter quarters of Captain Amundsen's expedition. The 

 results are shown in the third column of Table I., and are plotted 

 by a broken curve in Fig. i. It will at once be seen that the
