1981 CLItIATOLOGICAL REPORT
R. J. Allen, Jr. huMIE LIBR ARy

This report summarizes weather data for 1981 at the A riculWIlSke$arch and
Education Center, Belle Glade, Palm Beach County, Florida. Lat. 260 40'; Long. 80
38'; Elevation 11.5 ft m.s.l. ILFA.S. f Florida
Temperature: Coldest temperature recorded was 280F on January 19. Te rtu s
in the 30's occurred 11 days in January, 1 day in February, 8 in March, and 4 in
December; and in the 40's 15 days in January, 9 in February, 6 in March, 8 in Nov-
ember and 8 in December. January average minimum temperature was 9.8* below the
long term 56 year average. January temperatures averaged 9.80 below the long term
56 year minimum average and 7.30 below the long term maximum average. The temp-
erature for the year averaged 0.20 below normal minimum and 0.50 below normal max-
imum (See page 16). These temperatures are recorded in a standard Weather Bureau
Instrument Shelter at 5 feet above ground. Lower temperatures will usually occur
at ground level and in the so-called backlands, especially on clear nights with no
wind.
Frost: A freeze with 280 occurred on January 19, and light to moderate frost
occurred on January 1, 13 and 14, February 4, March 21, and December 11, 12 and 20,
with temperatures of 32 to 34 being recorded in the shelter.
Rainfall: Total for 1981 was 45.89 inches, a deficit of 10.92 inches below
the 56 year average. August rainfall of 17.37 inches set a new record high for
this month, 9.32 above normal. February, May and November had a combined excess
of 3.26 inches and the other eight months had a combined deficit of 23.5 inches,
April being the lowest with 0.41 inches (See page 15).
Relative Humidity: The lowest month was March with 6.4 hours per day above
90% and an average low of 39%. Highest was August with 15.2 hours per day above
90% and an average low of 60%.
Wind: There were no hurricanes in the area this year. Mind travel over
300 miles for the day occurred on 3 days, January 12 and larch 22 and 23, and over
200 on 14 additional days. These records were taken at the old weather station where
there are buildings, trees and machinery obstructing the wind travel. At the new
station set up in December in the center of Section 10 there are no obstructions
and the wind travel is averaging over 40% higher than at the old station.
Solar Radiation: Incoming sunlight energy set a new annual record of 430
Langleys per day which is over 7% above the previous 10 year average of 401 Langleys
per day. New record highs were set in January, February, March, May and July,
and a new record low set in August (see page 16).
All observations, except solar radiation, which is calculated from a recorder
strip chart weekly, are made at 8 A.MI. each morning and cover the previous 24 hour
period (16 hours of the previous day and 8 hours of the current day). However, to
assist local agricultural interests in comparing this weather data to their obser-
vations of plant growth and product quality, the daily data is presented in this
report on a Calendar Day basis. An explanation of the various columns follows:






Air Temperature -- Recorded in a standard shelter at 5 feet above ground.
Minimum a.m., usually occurs in the early morning hours.
Maximum p.m., usually occurs in the afternoon.

Mean Average of above, approximates the average temperature for the day.
Solar Radiation -- Sunshine energy reported as langleys (gram calories per cm2).
r1easured by a solar pyranometer and calculated from a recorder strip chart
every Friday morning.
Rainfall -- Inches of rainfall measured at 8 a.m. is credited to the previous day
even though some may have fallen after midnight.
Evaporation -- Loss of water from a standard evaporation pan. Measurement at 8 a.m.
is credited to previous day since most evaporation occurs during sunshine hours
and when temperature is high and humidity is low.
Wind --
@ 2 ft. ililes of travel at 6 to 8 inches above the evaporation pan. Count at
8 a.m. credited to previous day since wind affects evaporation and velocity is
usually low during early morning hours.
@ 20 ft. Miles of travel at approximately 10 feet above the roof of the
weather house is recorded, along with direction, on a strip chart. Count at
8 a.m. is credited to previous day to compare with wind at 2 ft.
Soil Temperature -- a.m. minimum and p.m. maximum occurring 4 inches below the sur-
face of bare soil.
Relative Humidity --
Hours over 90% Continuous hours over 90%, ending on calendar day. Usually
starts in late p.m. of previous day.
Minimum % Usually occurs in afternoon when temperature and radiation are
highest.

Wetness -- Continuous hours, ending during calendar day; that moisture from rain or
dew stays on foliage. May start in late p.m. of previous day.
Several other tables of general Interest weather data which have appeared in
previous climatological reports have been up-dated and included in this report.
