TO TELL WEATHER
Is DAYS AHEAD
Prof. CarOthers VIII Attempt
Forecasts Long In Advance.
WORKING ON NEW THEORIES.

Houston (Tex.) Observatory Man Be-
lieves Hot Areas on the Sun Cause
Periodical Changes In Our Atmos-
pherio Conditions.
Working on the theory that certain
highly heated areas on the sun are the
causes of marked changes in the at
mospheric conditions Of the earth and
that the influence of these areas can
be determined ahead of time, Profess
sOr W. F. Carothers of the Carothers
observatory, in Houston, Tex, plans
to make weather forecasts twenty-five
days ahead for the southwest. Pro-
fessor Carothers has long been study
ing this problem and has written arti-
Giles on the subject that have attracted
wide attention among scientific men,
and he believes that under actual serv-
ice over a long period he will be able
to demonstrate that his theories are
correct
Professor Carothers took up the
work of meteorology many years ago
and through it was led into study of
the sun. When he began this work
meteorOlogists had a theory that the
sun was responsible for great weather
changes, but did not know just how it
acted, whether by heat, magnetism or
attraction. The work at Houston was
begun with an inquiry into the wealth
er movements which constantly sweep
across the northern ATTITUDES, consist
ing of a sort Of cyclonic forerunner
marked by strong winds, rain or snow
and a low barometer and followed by
a cold and clearing spell marked by a
high barometer. These movements
were known to originate near the poles
and to move almost around the earth.
First Conclusions.
The first conclusions reached by Pro-
fessor Carothers in common with 9TH
er investigators, including the present
chief Of the federal weather bureau,
were that the periods of high barome-
ter dominated those of the cyclonic or
low barometer and that the cold tenn
perature that marked high barometic
Next the observer turned to the sun
as means of solving the problem.
He devised a tabulating disk that Is
now we'll known to students of the |
sun and recorded the observable |
changes on the sun In Its revolution. |
For two years he mas been comparing |
his observations of the sun with the |
changes of the weather and has de-
cided that changes there and in condi- |
lions here closely correspond. He de-
clares he has established a law Of |
serial periodicity" in the high barome-
trio conditions, which come with varia-
tons each twenty-five days, corre-
spending with the revolution Of the
sun.
In a discussion of the matter Pro-
fessor Carothers thus explains the fur
Their theory on which he is working:
"Now we come to the part Of my
work which IS as yet an uncontirmed
hypothesis" he says-'that is, that
this serial periodicity is caused by rel
atively hot areas scattered around the
revolving disk of the sun, which In
passing so as to face the earth directly
produce extra upheavals Of heated air
at our equator. These are forced by
the heat into high upper strata, where
a chilling takes place: the moisture is
precipitated lit rains daily at the heat
equatorl, and thence they pass high
above our heads to the northern lati-
tudes, where they come down as cold
waves, or highs Every time the sun
turns around on its axis these upheav-
ais recur, and hence the coming Of the
in serial periods Of twenty
i've days.
