THE WINDS FROM THE "GREAT ICE" 



ing as it must from above, this air must in turn be 

 replaced by that of inwardly blowing currents at 

 some higher level. The complete air circulation 

 above the Greenland ice-cap consists, therefore. 



of high inward-blowing winds toward the central 

 region, where air is slowly settling to the surface 

 of the ice-cap, from which central area it reverses 

 direction and passes out in all directions over the 

 surface toward the margin of the dome. The Green- 

 land ice-cap is thus the northern wind pole of the 

 earth, which is technically described as the Green- 

 land glacial anticyclone. The southern reversing 

 area of our atmospheric circulation is the Ant-
