AMERICAN STORMS.

The Tracks of Most Of Them Lead to the
st. Lawrence River.
One of the chief interests, aside
from the values they have in respect
to forecasting. in the study of charts
of storm tracks, consists in comparing
them month with month, in order to
observe the changes that take place
with the progress of the seasons. 1t
was shown on the August map that
the summer storms, in the majority of
cases, originate in three places: in AL
berta, Colorado, and the West Indies.
On the other hand, in September the
chart indicates that they arise in at
least six places. We have one set of
storms generating in Alberta, at which
thirty-eight were observed in ten years;
there were eleven noted that entered
the North Pacific coast of the United
States; next five were observed to com
mence their activity on the northern
plateau of the Rocky mountain dis
trict; also seven developed over tho
isolated plateau of Colorado; five APP
peared on the west coast of the gulf of
Mexico; finally seven tropical hurri-

These all pursued their paths to the
gulf of st. Lawrence, in the neighbor-
hood of which they left the field of OBJ
servation. The Alberta storms run |
along the northern boundary of the
United States in the northwest, cross
the lake region, and advance down the
st. Lawrence valley, reaching the gulf
in about three days. 1t will be OBJ
served that these tracks have a strong
tendency to loop down near the begin
ming of their paths over the Rocky
mountain slope into North and South
Dakota, whence they recover the main
track in the neighborhood of Lake
Superior The North Pacific storms
those from Wyoming and Idaho, as
well as the Colorado storms, in tweu-
ty-four hours find themselves on the
main track in the lake region. whence .
they go to the gulf of st. Lawrence.
These four groups belong very clearly
to one family, and have their rise on /
the northward side of the great high :.
pressure belt that extends around the
globe in about latitude thirty degrees,
thirty-fve minutes, except where it is
United States this belt leaves the u
Atlantic coast near South Carolina
but it enters this country in northern u
California or Oregon, nearly ten de- n
yrees further north. The DETECTION a
thus observed is no doubt largely due +
20 the elevations of the Rocky noun fl
ain districts. 81
On the southern side of the high belt 81
We find another system of storm gem T
'ration, because the air of this belt h
must flow off on both sides, south as e;
veil as north, though the quantity re- ii
urned to the southwark is less than III
hat to the northward. Thus, we find NJ
he five gulf of Mexico storms, which II
sually advance to the gulf of st. Law h,
ence over the Atlantic states; also, we 6,
ave the West Indian storms, which :,
re developed further east, in the calm ~
