The effect of the errors attaching to the computed heights upon the values 

 of the pressure reduced to sea-level, has been computed from the formula 



b 



db = 



dh 



29.206 (273 -f- t) 



and the values of db are inserted in the last column of the Table. 



On the Barrier, lat. 79" — 83^ the pressure increases with latitude; it 

 is constant to 86*^, but then decreases rather rapidly, and at last more 

 slowly to the Pole. The Barrier has an anticyclonic distribution of pressure, 

 but the Plateau has a distimi, revmrkably low pressure. 



VII. The Winds. 



The Wind-Roses have been computed specially for 

 The Barrier: Framheim to lat. 84° 53' 

 The Glacier: lat. 84053' to lat. 85" 36' 

 The Plateau : lat. 85" 36' to lat. 89» 58' 



The numbers are weighted means referred to 8 points. 



Wind- Frequency, per Mille 



The direction of the maximum of frequency at Framheim is E, on the 

 Barrier S by E, on the Glacier SE by S, and on the Plateau SE. From 

 the interior to the coast the prevailing wind turns to the left from SE to E. 



Dynamic Wind-Roses m. p. s. 



The strongest winds are E to SW on the Barrier, E on the Glacier, 

 and SE on the Plateau. At Framheim the strongest winds are NE'^' in 

 the summer months.
