78% NITROGEN
21% OXYGEN
0.9% ARGON
0.03% CARBON DIOXIDE
TRACE ELEMENTS - NEON, HELIUM,
METHANE, OZONE, NO2, KRYPTON,
HYDROGEN, XENON

MOST IMPORTANT OF THESE GASES FOR
WEATHER PRODUCTION IS CARBON DIOXIDE
DUE TO ITS EFFECT AS A GREENHOUSE GAS


CO2 MAY BE INCREASING GLOBAL
TEMPERATURES. SOME SCIENTISTS PREDICT
THAT CO2 LEVELS WILL DOUBLE FROM 1900
TO 2050 WHICH MIGHT CHANGE CLIMATE

12 - 19 MILES ABOVE SURFACE


MOLECULAR O2 IS BROKEN DOWN TO
ATOMIC O1 WHICH COMBINES WITH AN O2
TO PRODUCE O3
AVAILABILITY OF SHORTWAVE RADIATION TO
BREAKDOWN O2 AND ATMOSPHERE IS DENSE
ENOUGH TO ALLOW FOR THE COMBINATION

ALL SUBSTANCES ARE COMPOSED OF
MILLIONS OF MOLECULES THAT ARE IN
MOTION. THIS MOTION IS KNOWN AS
KINETIC ENERGY. TEMPERATURE IS A
MEASURE OF THE AVERAGE ENERGY OF THIS
MOTION.

LIQUID-IN-GLASS AND ELECTRICAL
THERMOMETERS HAVE A BETTER RESPONSE
TIME (HOW QUICKLY THEY ADJUST TO
CHANGES IN TEMPERATURE) THAN DOES A
BIMETAL STRIP

CRICKET CHIRPS
ADD THE NUMBER 40 TO THE NUMBER OF
CRICKET CHIRPS YOU COUNT IN A 14
SECOND PERIOD AND THIS WILL EQUAL THE


AMOUNT OF HEAT REQUIRED TO CHANGE
THE TEMPERATURE OF 1 GRAM OF A
SUBSTANCE BY 1 DEGREE CELSIUS


HIGH SPECIFIC HEAT MEANS THAT IT TAKES
MORE TIME/ENERGY TO RAISE THE
TEMPERATURE AND THAT THE SUBSTANCE
WILL HOLD THE HEAT LONGER
LOW SPECIFIC HEAT MEANS THAT THE
SUBSTANCE HEATS AND COOLS QUICKLY

LINE THAT CONNECTS EQUAL TEMPERATURE

RESEARCH INDICATES THAT THE IDEAL
TEMPERATURE FOR HUMAN COMFORT IS
WHEN THE OUTSIDE AVERAGE DAILY
TEMPERATURE IS 70 F. ENGINEERS HAVE
DETERMINED THAT THE OUTDOOR
TEMPERATURE AVERAGE MUST BE 65 F IN
ORDER THAT THE INDOOR AVG = 70F



AMOUNT OF HEAT REQUIRED TO RAISE THE
TEMPERATURE TO 65 F
EVERY ONE DEGREE BELOW 65 F = ONE
HEATING DEGREE DAY
HIGH = 55 & LOW = 45 ; AVG = 50 SINCE 50
IS 15 DEGREES BELOW 65F; THEN THE
HEATING DEGREES = 15



AMOUNT OF COOLING NEEDED TO LOWER
YOUR TEMPERATURE TO 65 F
EVERY DEGREE ABOVE 65 F = ONE COOLING
DEGREE DAY
IF HIGH = 90 & LOW = 70; AVG = 80 SINCE
80 IS 15 DEGREES ABOVE 65 THEN YOU HAVE
15 COOLING DEGREE DAYS
