AEROLOGICAL OBSERVATIONS
By L. T. BAMITELS
Free-air temperatures during November were consider-
ably above normal at Ellendale, moderately above at,
Ro a1 Center, slightly below at Broken Arrow and ~noder-
This is in close agreement with the distribution of surface
departures shown in Chart I.
The departures of free-air relative humidities were in
general, of opposite sign to those of temperature.
Free-air vapor pressures were above nornial at all
levels a t Ellendale, Royal Center, and Broken Arrow and
in the upper levels a t Due West and Groesbeck.
From Table 2, it will be noted that free-air tenipera-
tures a t the navnl air station, Pensacola, were in close
agreement with t'hose at Groesbeck, being slighbly higher
a t the former station. Those at San Diego were highest
of all stations.
At 1,000 meters above sea level the free-air resultant winds indicated a southwesternly c,ompone,nt over t,he
middle Mississippi Valley and lower Lake region and northwesternly and westernly over the remainder of the
country. At 3,000 meters none. of the resiiltant direct.ions contained an appreciable southernly component, escept
in the extreme Northwest. The easterly component found at 1,000 meters over Brownsville and Key Wsst,
changed to westerly at 2,000 meters over Brownsville and to north-northwesterly a t 3,000 meters over Key
West. The nionthly resultants for a represcntat,ivct group
of stations are shown in Table 3.
A very severe sleet storm occurred at Ellcndnle on
the 18th, 19th, and 20th. The kite record of the 18tmh
was of unusual interest in that it showed a innrked
rise in temperature from the 17t'h to 18th betwe,en
3,000 and 3,500 meters. The, increase amount,ed to 7'
C. at the higher level and was unque.stionably greater at still higher elevations beyond the limit of the flight.
A significant fe,at,ure of this high inversion was t,he fact
that the air within it was saturated and 10-tenths alto- stratus clouds from the south-southeast prevailed. On the morning of the 18th a deep LOR (29.3 in.) was cen-
tral over Colorado.
ate T y below at Groesbeck and Due West. (See Table 1.)
