and wind; the second is the constant relation of tem- 

 perature and wind. 



It is not meant that wind-storms never accompany 

 or follow great changes of pressure, but that the relation 

 often fails, and is not constant and rehable. Severe wind- 

 storms may occur when the barometer is steady or shows 

 only gentle movements, as in the first few days of May 

 1908. On the other hand, and more commonly, very great 

 rises and falls of the barometer may occur in compara- 

 tively calm weather, as between June 1 and 12, in which 

 period there was only a few hours of moderately fresh 

 bree^ze on the 4th. June 19 to 22 is a more striking 

 example, when a very rapid rise of barometer occurred, 

 without any decided wind-storm. But the wind-storms 

 between May 5 and 15 accompanied considerable fluctu- 

 ations of the barometer. 



The relation of wind and temperature is shown in the 

 remarkable parallelism of the two curves. A wind-storm 

 is almost invariably followed by a rise of temperature, as 

 indicated by the dotted lines. The only exception in the 

 period illustrated is the moderate storm of May 20 to 21, 

 when there was no appreciable rise of temperature. 



Cold blizzards have been noted. The worst of all was 

 that of July 25 to 27, when the daily means ranged from 

 minus 22.0° to minus 29.0°, and as low as minus 35.0° 

 was recorded. 



The rise of temperature during a blizzard amounted 

 to as much as 32° on July 9, and even greater rises have 

 been noted. 



The intimate relation between wind and temperature 

 continues throughout the cold weather, but almost disap- 

 pears in the summer months. The relation of wind to 

 barometric pressure (possibly on account of the proximity 

 of open sea) is also much more regular in the summer.
