TEMPERATE ZONE OF NORTH AMERICA, EAST OF THE ROCKY MOUNTAINS. 



This region has much in common with Arizona and New Mexico, as to the 

 mean direction and percentage of its winds. In summer a strong current from the 

 south sets in to supply the air which is rising on the interior plateaus. In the 

 winter, on the contrary, the prevailing winds are N. W. and the mean direction 

 generally between N. and W. In winter the winds are more variable than in sum- 

 mer, and even southerly winds are sometimes experienced. The boundaries of this 

 region are the great axis of the continent on the W., the Rio Grande on the S.W., 

 the Gulf of Mexico on the S. E., and the Mississippi on the E. The northern 

 boundary is rather doubtful, but yet, as far as 45° N., winds from the S. E., S., 

 and S. W. prevail in summer. (See also maps. Plates 5, 6, 8 and 11.)
