Atlantic coast this east wind, saturated
with moisture, gives out rain as it |!
carried upward.
AS the centre approaches the wint
swings round to the southeast, ther
to the south, and southeast and south
winds bring rain to the Mississippi
Valley, since they bring moist air from
the Gulf.
As the centre passes the wind turns
to the southwest and west, and com
monty becomes dry, since it comes of
the great arid tablelands, and the rair
ceases.
But on the Pacific coast. since the
supply of moisture lies to the west
ward, the west winds are saturated
with moisture, and at some seasons
bring rain. Hence the rain falls after
the centre of the storm has passed in
stead of coming in advance of it.
The rain has seasons, as tempera-
ture has, and while in most parts oi
the country the hot season is the dry
one and the cold season the rainy one,
if the Rocky Mountains things are re-
versed-the rainy season comes in
the summer. To understand all this
we must go back little.
It was stated above that as we go up
ward and as we go northward the air
becomes colder. This is true in gen.
eral. but in certain cases the rnle is
reversed.
In the summer both land and sea
receive heat from the sun and accu-
mulate it. The sea is constantly
in motion, and its waves and currents
disperse the heat, carrying it from the
equatorial regions toward the poles
and so tend to equalize the tempera-
ture of the water. That about the
equator is not greatly warmer than
that farther north and south.
But with the land there is no way
of thus equalizing temperature. The
lanu in the summer becomes greatly
heated and in the winter greatly
cooled.
Hence, in the summer, the land is
warmer than the sea in the same lati-
tude, and in the winter cooler.
Indeed, lands situated north of the
sea for long distances, ,and lands which
are far above the sea, may be warmer
in the summer than the sea, and hence
cannot condense moisture from satur-
ated air.
ON THE PACIFIC COAST.
It is because the temperatures over
the Eastern States are in summer often
warmer than those over the Gulf and
the Atlantic that is rains less fire.
quently there at that season than in
winter when the temperature condi-
tions are reversed.
On the Pacific coast these condi-
tions are similar, but there is a much
greater difference in the amount of
rain in summer and winter. In fact,
instead of calling the seasons summer
and winter, the people speak of them
as the dry and wet seasons. In the
summer it hardly ever rains; but in
Western Washington and Oregon It
rains nearly all the winter. While
southwark the amount of winter rain
diminishes with the latitude. The
farther south the less is the rainfall.
The temperature of the Pacific
Ocean, on this coast, is almost uniform
everywhere and at all times of the
year. and the saturated air currents
which come off 1t are also uniform
| in temperature. In the winter these
currents encounter cold land, cold
er becaues it is high for the Pacific
coast is bordered by mountains.
It is, of course, colder in the north
than in the south, and corresponding
! ly the rainfall is heavier.
The air currents are therefore al
| most completely drained OF their
moisture by the time they have pass
ed the SUBMITS of the Cascade and
Sierra, and blow thence eastward as
dry winds.
In the summer, on the other hand,
the land, excepting the highest noun
tains, is warmer than the air currents
and they pass over it without losing
moisture.
| Now let us follow these air currents
eastward and see what happens tc
them. In the north they lose little
moisture on the Coast Range little
more on the Cascade and Sierra, and
those which cross south of the Sierra
lose none at all.
Altogether, the eastbound winds oi
summer from the Pacific enter the
Rocky Mountain region as mois'
winds. There they encounter an al
most endless succession of high range:
and valleys.
One after another these ranges draw
from the atmosphere little moisture
mostly in the form of showers.
Of all these mountain ranges, those
of Colorado, being the highest, gel
the most moisture. Hence this is the
rainy season of the Rocky Mountains
1t rains simply because at this season
only the air currents are able to bring
their moisture over the mountain bar
riers to the westward.
If there were no mountains OF the
Coast Range, Cascades or Sierra, there
would be no desert in Our country.
