WINDS OP THE GLOBE. 



long-continued; while in the territories the observations are mostly for short 

 periods and the stations far between. 



The lakes do not seem to cause monsoons of any consequence. There are, it is 

 true, day and night winds on their shores, but they do not extend inland to a 

 great distance.^ 



The wmds of the Atlantic coast of North America, from Labrador to Florida, 

 have some common features, notwithstanding the great difference in latitude.

The general climatic features of the Atlantic slope are somewhat like those of the 

 trans-Mississippi region, the winds of summer being more southerly than those of 

 winter, the N. W. prevailing in winter, the S. W. in summer. The distribution of 

 pressure is here, as elsewhere, instrumental in producing this system of Avinds. The 

 region we are considering is open to the influence of the Atlantic, and as on other 

 oceans a belt of highest pressure is seen to prevail there about 30° L. N., as 

 shown on Plate 14. This would then cause southerly winds. But in win- 

 ter this influence is counteracted by the higher pressure to the west, in the inte- 

 rior of the continent. Thus, the N. W. is prevailing in the colder months of the 

 year. In summer there is nothing to check the influence of the higher pressure 

 to the south, on the Atlantic Ocean and in the South Atlantic States. Therefore 

 S. W. winds are seen to prevail in summer. (See Plate 8.) 



' See the examination of the winds at the Western Reserve College, Ohio, at the different hours 

 of the day, by Prof. Coffin, on p. 299.
