SOME HOT FACTOIDS ABOUT

TRIPLE DIGIT TEMPERATURES

 (100 F / 37.7777C *)

IN EL PASO TEXAS

David J.Novlan /  Climate Focal Point /  WFO El Paso

FROM 1879 THROUGH  September 2013 THE MAXIMUM TEMPERATURE HAS REACHED 100 DEGREES F OR HIGHER 2086 TIMES.

ON THE "AVERAGE" EL PASO EXPERIENCES 15.4 DAYS OF TRIPLE DIGITS PER YEAR.

* FROM 1981-2010 EL PASO AVERAGED 20.5 DAYS OF TRIPPLE DIGITS PER YEAR. *

SINCE 1879 NO YEAR HAS GONE WITHOUT AT LEAST ONE TRIPLE DIGIT OCCURRENCE.

THE FOLLOWING YEARS SAW ONLY ONE OCCURRENCE OF TRIPLE DIGITS.

1899 1904 1914 1917 1919 1926 1941 1967

 THE HOTTEST DAY (114 F) I N EL PASO OCCURRED ON JUNE 30, 1994

1994 ALSO WAS THE YEAR A RECORD CONSECUTIVE  23 DAYS OF TRIPLE DIGITS OCCURRED FROM JUNE 23 THROUGH JULY 15

THE EARLIEST OCCURRENCE OF 100 DEGREES WAS ON MAY 8, 1989.

THE LATEST START TIME OF 100 DEGREES WAS ON SEPT. 2, 1899.

THE LATEST OCCURRENCE OF 100 DEGREES WAS ON SEPTEMBER 16, 1956 (101 F)

THE 'AVERAGE' STARTING DATE FOR TRIPLE DIGITS IS JUNE 14.

THE 'AVERAGE ENDING DATE FOR TRIPLE DIGITS IS AUGUST 2.

MONTHLY FREQUENCY DISTRIBUTION OF TRIPLE DIGITS

(NUMBER PER MONTH AND PERCENTAGE )

MAY JUNE JULY AUGUST SEPTEMBER
63 875 708 257 27
3.3% 45.3% 36.7% 13.3% 1.4%

NOTE THE ASYMMETRIC DISTRIBUTION ABOUT JULY CENTERED ON JUNE.  JUNE IS THE MONTH WITH THE HIGHEST SOLAR ANGLES AND LONGER DAYS BUT JULY THROUGH MID SEPTEMBER HOST THE RAINY SEASON IN EL PASO (THE MONSOON SHIFT OF THE PREVAILING WEST WINDS TO THE EAST) IN WHICH AROUND 50% OF THE ANNUAL PRECIPITATION FALLS...SKEWING THE TEMPERATURE CURVE.

-------

SYNOPTIC CONSIDERATIONS: TRIPLE DIGITS ARE MOST LIKE ESPECIALLY IN RUNS OF CONSECUTIVE DAYS WHEN SUBTROPICAL HIGH PRESSURE ALOFT (ASSOCIATED WITH SUBSIDENCE-DOWNWARD MOTION IN THE ATMOSPHERE WHICH IN TURN  WARMS THE ATMOSPHERE AND SUPPRESSES  CLOUD AND THUNDERSTORM DEVELOPMENT) POSITIONS ITSELF OVER NEW MEXICO AND OR ARIZONA AND NEW MEXICO RATHER THAN TO THE EAST OF NEW MEXICO (WHICH IS FAVORABLE FOR MOISTURE INPUT).

 77% OF THE TRIPLE DIGITS ARE <= 103 F

 THE PROBABILITY DENSITY FUNCTION OF THE TRIPLE DIGITS CAN BE REPRESENTED BY AN EXPONENTIAL DECAY FUNCTION OF THE FORM:

P(T) = A*e(B/T)

WHERE T = TEMPERATURE IN DEG F...A = 2.433*10(-18)......e=2.71........B=44.01.735

-------------------

MOST LIKELY TIME TO ENCOUNTER TRIPLE DIGITS:

THERE IS  A 67% LIKELIHOOD OF HAVING A TRIPLE DIGIT BETWEEN JUNE 11 AND JULY 18

BOTH JUNE 23 AND JUNE 28 HAVE EACH SEEN THE MOST  DAYS  (49)   WITH TRIPLE DIGITS SINCE 1879

-----------------

NOTE TEMPS 1879-1886 SHOW HIGH BIAS DUE TO SHELTER LOCATION:
