YES, It WAS HOT BUT
NOT A RECORD BREAKER
Mr.. Jesunofsky Explains the Relation
Between Sun Spots, Tempera-
lures and Rainfall.

Yesterday wasn't record breaker as
fas as temperature is concerned. but
ii was a sizzler. The highest tempera-
ture Of the day-110 degrees-was
reached at 4: 80 p. m This is seven de-
grees above the normal for this day.
The day started out nice and cool
just as though the sun had no inten-
tons of raising temperatures to the
boiling point. At a. m. II was ~. at
it dropped to % and at 8 a. m. the
coolest part of the day was reached -
40 degrees Then as the sun came up
over the horizon the mercury jumped
and started out on a series of antics.
1t jumper % degrees in -four hours.
standing at 81 at 10 o'clock At noon
il was 1913 at O'Clock loo and at 3
l09. The high point of the day was
reached a half hour later, when 10
was reached.
The present year thus far has been
one of extremes There is big eX-
cess in degrees of temperature and
quite a deficiency i'm rainfall. For this
month. which is hardly started, 40 de-
grees of excess in temperature are
registered and for the year Arb de-
greeS. In addition. there is a def
cheney in the rainfall of 1.45 inches.
These figures taken as a whole and
their relation to statistics Of former
years tend in a general way to bear
out a recent and extremely interesting
theorem of the scientists in regard to
the effect Of sunspots on the weather
1t is a generally accepted fact by
the meteorolOgists." said l.. y. Jesun-
.nfslyN~ nf IN
bureau. Yesterday. that sun spots do
have an effect on temperature and
rainfall When a mass of figures. rep
resenting temperatures and rainfall,
extending back over many years. is
compared with the periods of maximum
and minimum intensity of the sun
spots it is seen at once there is GER
tain well defined relation between
them. Comparisons and deductions
show that the cycle of sunspots-that
is. the time 1t takes them to spread
from minimum size to their greatest
AREAS about eleven years. As the
spots increase i'm size the heat and
rainfall increases. and as they decrease
drouth and cooler temperatures pre-
vail This gives period of five and
a half years in which the rainfall may
be expected to be a little above the
normal and the temperatures also a
little in excess of normal Then the
dry cycle comes along and cooler
temperatures and less moisture pre-
vail. OF course. we are dealing i'm gem
eralities and no one day or month or
even a single year can be taken as
exemplifying the corralary, but the
average is maintained, proving the re
latiOn between the spots and the
earth's climatic conditions.
The last period of drouth was in
1903. That perior corresponds with
the time when the sun spots were de-
creasing to their minimum. If we take
1902 as the minimum we find that 1913
is the next minimum. or time when we
may reasonably expect the close of the
minimum period or dry cycle. We are
now in the minimum period and APP
preaching the end Of it.
This does not mean for a moment
that we are going to suffer from lack
OF rain. We can expect with almost a
certainty that we shall have rain be-
tween July l and July 10 if not before |
1t may not he enough to do us very
much good, but we will have a little !
And then through August we may ex-
pect more rain, but the average for the
year will probably be a little under the
normal, which is 7.S7 inches for this |
section.
In regard to the present warm
weather / will say that | hardy think
il will keep up unbroken for the rest
of the summer. II is too early in the !
year for that and we may expect a
period of cooler weather before the real !
summer heat starts in. / don't think, |
however, that the thermometer will |
drop as far below the normal for the |
rest of the year as it has shot above |
it in the last five mOnths-that is, we |
will come ont at the end of the year |
with few degrees Of excess tempera.
