238 F. Waldo—Rise and Fall of the Wind in the U.S. 
very rapid increase to 1:1 m. p. h. or 1:2 m. p. h. as the extreme 
southwest and the western coast isapproached. On the Pacific 
coast there is an increase from less than 0°3 m. p. h. at the 
extreme north to 1:2 m. p. h. and 1:1 m. p. h. at the center 
and south. 
To the east of the central meridianal region of 0:5 m. p. h. 
there is probably little change on the average at the north, 
although there is some lack of uniformity in the data for 
various stations, the rate of increase varying from 0:4 to 0°6 
m.p.h. At the center and south there is a slight decrease to 0-4 
m. p. h. with a small sectional local increase to 0°6 m. p. h. in 
the central Ohio River Valley, and local decrease to 0°3 m. p. h. 
in the lower Mississippi Valley. 
There is a local increase to 0°7 m. p. h. in southeastern Texas, 
and a decrease to 0°4 m. p. h. on the southeastern coasts of the 
United States. 
For the Year along about the 95th meridian (slightly to the 
east of it at the north and a little to the west of it at the 
south), the rate of rise of the wind is 05 m.p.h. To the 
west of this at the north there is at first a small local increase 
to 0°6 m. p. h. and then a gradual decrease to 0-4 m. p. h. 
At the center and south there is at first a slight, and then, at 
the extreme west, a very rapid increase to about 0°9 m. p. h. on 
the coast. At the south there is at first a slow and then a rapid 
increase to 1:1 m. p. h. or 1:2 m. p. h. with a further decrease 
to 1:0 on the coast. 
To the east of the 95th meridian there is at the north a rapid 
decrease to about 0°35 m. p. h. which is preserved to the 
Atlantic; but there is some disagreement for individual sta- 
tions. At the center there is an increase to 0°7 m. p. h. or 0°8 
m. p. h. in the middle Ohio Valley and then a decrease to 0°3 
for the exposed Atlantic coast stations. At the south there is 
a decrease to 0°3 m. p. h. on the lower Mississippi, and then an 
increase to 45 m.p.h., which extends quite to the Atlantic 
coast.
