Weather

You can determine how far away a lightning bolt is in miles by counting the seconds between the flash and thunder, and dividing by 5.
Cold water robs the body’s heat 32 times faster than cold air.
Notable temperatures:
Fahrenheit Celsius Kelvin
212° 100° 373° Boiling point of water at sea level
136° 58° 331° Highest recorded atmospheric temperature
El Azizia, Libya, September 13, 1992
94° 34° 307° Highest average annual temperature
Dallol, Ethiopia
32° 273° Freezing point of water at sea level
-129° -89° 184° Lowest recorded atmospheric temperature
Vostok, Antarctica, July 21, 1983
-492° -273° Absolute zero
The wind chill is how cold it feels outside when the effects of temperature and wind speed are combined.

To calculate wind chill:
WC = 0.0817 x (3.71V(.5) + 5.81 - 0.25V) x (T - 91.4) + 91.4
where
(.5) is an exponent,
WC is the wind chill in degrees Fahrenheit,
V is the wind speed in miles per hour,
and T is the temperature in degrees Fahrenheit
A solstice is the point in time when the sun is at a maximum or minimun angle from the Celestial Equator, and days and nights are the most unequal in duration. In the Northern Hemisphere, the winter solstice is on or near December 21, and the summer solstice is on or near June 21.
Eight climactic zones in each hemisphere are defined in terms of precipitation. They are:
  1. Equatorial – rain in all seasons
  2. Tropical – summer rain with dry winter
  3. Semiarid Tropical – slight summer rain
  4. Arid – dry all year
  5. Dry Mediterranean – slight winter rain
  6. Mediterranean – dry summers with winter rain
  7. Temperate – precipitation in all seasons
  8. Polar – little precipitation in all seasons
Five climactic zones are defined in terms of temperature. They are:
  1. Tropical – annual and monthly averages above 68° F
  2. Subtropical – 4 to 11 months above 68° F, and the balance between 50° and 68° F
  3. Temperate – 4 to 11 months at 50° to 68° F, and the rest cooler
  4. Cold – 1 to 4 months at 50° to 68° F, and the rest cooler
  5. Polar – 12 months below 50° F

Environment

The Five Outward Bound Principles:
  1. An Enterprising Curiosity
