220 HOBBS— ROLE OF GLACIAL ANTICYCLONE lApHi 24, 



The Fixed Low Pressure Areas Marginal to the Inland-Ice 



Masses. 



Antarctica. — The Filchner expedition seems to have estabHshed 

 the fact that a fixed cyclonic depression hes off the border of the 

 Antarctic continent covering the indentation of the Weddeli Sea/" 

 In the hght of this discovery it now seems highly probably that a 

 similar fixed depression lies above the indentation of the Ross Sea 

 on the other side of the Antarctic regions and in nearly similar re- 

 lationship to the inland-ice on either sideJ^ 



Greenland. — It is well known that a fixed low which is espe- 

 cially marked in the winter season lies off the southeast coast of 

 Greenland, usually assumed to wrap itself about Cape Farewell in 

 the form of a crescent, and extends northward into Davis Straits/* 

 Recent studies of the free atmosphere by de Quervain at various 

 points on the west and southwest coasts of Greenland indicate that 

 a stationary area of low barometer (probably continuous with this) 

 extends northward in Baffin's Bay as far at least as Disco Island/^ 

 The simultaneous studies carried out with pilot balloons at Akureyri 

 in Iceland, indicate clearly that a stationary depression lies over the 

 Greenland Sea to the northward of Iceland and between the Green- 

 land and Norwegian coasts/** The Danes from the journeys of 

 bottles set adrift during the expedition of 1906-08, determined that 

 the currents within this sea are such as would indicate a stationary 

 cyclone, since movements were southward along but off the Green- 

 land coast until near the latitude of Iceland, where they are de- 

 flected eastward and later northward so as to follow the trend of 

 the Norwegian coast.'^ Thus about both the glacial anticyclone
