WINDS OF THE GLOBE. 



another system of winds than those of the plains and valleys of Switzerland. The 

 winds of these isolated mountains rather give us an idea of what would be the case 

 if local influences were eliminated. The high peaks of the Alps would show us a 

 diff'erent system of winds. The following are the winds of Switzerland.

How much the winds are influenced by the locality on high mountain-passes, is 

 seen by comparing the Julier and Bernina, both situated in E. Switzerland, but 

 having nearly opposite winds, especially in spring and autumn. 



The winds in winter are remarkably like in Northern and Western' Switzerland, 

 the extreme difference being only 21°. The ratio of resultant is greatest in the 

 high stations, next in Northern Switzerland, and least at Geneva, where it is only 

 4. This last place is nearly on the border of the north winds in S. E. France. 

 There are greater diff'erences in summer, yet the mean direction is mostly between 

 the N. and W. (See Plate 9.) 



The western provinces of Austria have well-marked westerly winds in the N. 

 (Bohemia, Moravia, Vienna), belonging, in part, to the same zone as those of 

 Germany. This is also the case in the mountainous country (N. lUyria), and, as 

 is the case in Switzerland, the high station of Hoch-Obir, 7016 feet above the sea, 

 has a greater prevalence of westerly winds than the stations in the valleys. 



On the Adriatic coast N. E. and E. winds prevail, being, as in S. France, directed 

 from the land towards the sea. As there the prevailing wind is the strongest, so 

 it is here. 



The Bora of the Dalmatian coast is much feared by the seamen as a strong and 

 cold wind. Another wind often blowing here is the Sirocco from the S. or S. E. 

 It is originally a S. W. wind, but it is deflected by the highlands bordering the 

 Adriatic, and takes a course parallel to the shores. The following are the direc- 

 tions of the wind in this region : —
