H. MOHN. METEOROLOGY. [2nd. arc. exp. FRAM 



It appears from the preceding Tables that the velocity of the winds, 

 and the frequency of calms, have varied considerably in the different 

 years, or, as a closer inspection has shown, have been rather different 

 at the various winter quarters. 



This is shown by means of the following Table, in which V indi- 

 cates the mean velocity of the month, W the prevailing wind-direction, 

 and G the percentage of calms.

The second winter quarters, the Havnefjord, is remarkable for the 

 low velocity of its wind, the great number of calms, and the prepon- 

 derance of southerly or south-easterly winds. These winds have been 

 prevalent in 6 out of 11 months, while northerly or north-easterly winds 

 prevail only during 5 months. 



At the other winter quarters, northerly winds have been pre- 

 valent in almost all months. The velocity of the wind is higher, and 

 the frequency of calms less, than at Havnefjord.
