CONCLUSIONS. 247 



the continent as they do in the Ross Sea area. That the Gauss Station is under the influence 

 of anticyclonic conditions is made very probable by the large percentage of clear skies which 

 it has (see table 79) while it is made almost certain by the shape of its wind frequency 

 curve (see figure 35). A station which has snch a large proportion of calms and light winds 

 could not possibly be dominated by a cyclonic pressure distribution. We have also shown 

 (page 107) that the shapa of the wind frequency curve indicates pressure conditions similar 

 to those of McMurdo Sound, which, although so near to the low pressure area over the Ross 

 Sea, is governed by the Antarctic anticyclone and pressure waves.
