Curlous Meteorological Facts.

by Professor J. P. Epsy, Of Washing
ton, DC, we find the following in
structive concentrations
l. The rain and snow storms, and
even the moderate rains and SHOWS,
travel from the west toward the cast
in the United States, during the
months of November December,
January, February and March, which
are the only months to which these
concentrations apply
9. The storms are accompanied
with a depression of the barometer
near the central line OF the storm,
and o rise of the barometer in the
front and rear.
3. This central line of minimum
pressure is generally of great length
from north to south, and moves side
foremost toward the east.
This line is sometimes nearly
straihgt, but generally curved, and
most frequently with its convex side
toward the east.
). The velocity Of this line is such
that it travels from the Mississippi to
the Connecticut River in about tWen-
ty-four hours, and from the Connect
Cut to st. John, New Foundland in
nearly the same, or about thirty-six
miles an hour.
6. When the barometer falls sud
denly in the western part of New
England, il rises at the same time in
the valley of the Mississippi, and also
at St. John, New Foundland.
Z. In great storms the wind for
several hundred miles on both sides
Of the minimum pressure blows to-
wards that line directly or obliquely.

portion to the suddenness and great
ness of the depression of the barom-
cter.
8. In all great and sudden depros-
siOns Of the barometer there is much
rain or snow and in all sudden great
rains or snow there is a great depres-
sion of the barometer near the CEN
ter of the storm, and rise beyond its
borders.
10. Many storms are OF great and
unknown length from north to south,
reaching beyond our observers on
lhe Gulf of Mexico and on the
northern lakes, while their east and
west diameter is comparatively small
The storms therefore move side fore
most.
IL. Most storms commence in the
''far Vest beyond our most western
observers, but some commence in the
United States.
II. When a storm commences il
the United States, the line Of minu.
mum pressure does not come from
the ''far West" but commences will
the storm, and travels with it toWarC
the eastward.
ID. There is generally Il lull o.
wind at the line of minimum press
uTe, and sometimes a calm.
Il. When this line of minimum
pressure passes an observer toward
the east, the wind generally sooI
changes to the west, and the barOme
ter begins to rise.
Is. There is generally but LITTLE
wind near the line of minimum
pressure, and on each side OF tina
line the winds are irregular, but tent
outward from that line.
l6. The fluctuations of the baron
eter are generally greater in th,
northern than the southern parts o
the United States.
II. The fluctuations of the baron
eter are generally greater in the east
ern than in the western parts OF tn
United States.
Is. In the northern parts of tn
United States, the wind, general,
in great storms, sets in from tn
north of east and terminates from th
north of west.
10. In the southern part or th
United States, the wind generally
sets in from the south of east and ter
inmates from the south of west.
20. During the passage Of storm
the wind generally changes from tn
eastward to the westward by TIT
south, especially in the southern
parts of the United States.
q. The northern part of the storm
generally travels more rapidly TO
wards the east than the southern
part.
p. During the high barometer OF
the day preceding the storm it is gen
orally clear and mild in temperature
especially if very cold weather pre-
coded.
%. The temperature generally fall
suddenly on the passage of the cen
ter of great storms, so that sometimes
when a storm is in the middle of tht
United States, the lowest tempera
ture of the month will be in the Yves
on the same day that the highes
temperature is in the east.
