Washington, Sept. 23.-The extent to
which the business Of studying the
weather is International and world
wide is emphasized in a recent state
ment on the subject by the department
of agriculture.
The old-fashioned weather prophet
who looked at the sky, read the signs
and foretold what was going to hap
pen in the way of weather wouldn't get
far these days with the meteorological
sharps Of Uncle SAM
Foretelling the weather has become
matter not merely of having data
from large part of the world but Of
having Information about what is go
ing on in the upper air as well as in the
air near the earth's surface.
1t Is a fact that storms often sweep
from country to country and continent
to continent. Weather prediction to
an extent, therefore. becomes matter
of watching the course Of great storm
disturbances and calculating when they
will reach various regions. A storm
that RACES in western Canada today
may sweep over the Dakotas tomorrow
and in a week or two strike the British
Isles and leave wrecks IN its wake.
Development Of Meteoroio9y.
But much of the weather forecast
ing is concerned with manifestations
more subtle than this. 1t has been dis
covered there is a remarkable inter-
play between the atmospheric phe-
nomena In widely separated regions OF
otr &C. ~ hn
developments Of meteorology. For
example the state OF the barometer n
the interior Of Siberia in winter -
found to be related in an intimate way
to the movement and intensity OF
storms In the United States at the
same season. More striking correla-
lions exist, by virtue of which certain
meteorological conditions in certain
part of the world at one season give
some clue to the prevailing weather OF
another part OF the world In q later
season.
Cooperation between nations Is be-
coming more and more important. The
tendency Is growing for daily exchange
Of weather data by wire among the
civilized countries. For years. tho
United states, Canada and Mexico have
exchanged daily weather reports oJ
telegraph.
international Cooperation.
A few years ago. the United States
wea ther bureau inaugurated the exper-
iment OF making daily telegraphic
weather chart Of the northern hemis-
phere. This chart has become indis-
pensable to the forecaster. Recently
a similar chart has been made every
day at Toronto by the Canadian me-
teoroiogists, while in Europe plan is
on foot to prepare daily weather charts
for the whole of Eurasia. Wireless re-
ports from ships are rapidly filling up
the former gaps in such charts over
the oceans.
The work Of exploring the upper air
by means OF kites and balloons. which
ia carried on by the weather bureau.
is a part Of an international undertake
ing. cooperative work Of meteorolo-
g1sts thruout the world is directed by
an organization known as the 1nterna-
tional Meteorological Committee. 1t
holds triennial meetings. A plumber OF
International commissions are charged
with oversight Of particular lines OF
weather work. One. for instance with
headquarters at Strassburg. directs the
International survey OF the upper air.
