The Sun and the Weather
The ultimate source of energy on
Earth is the Sun. Wind would not
happen without temperature
differences. Evaporation would not
happen without wind. Clouds will not
form without water vapor, And there
would not be weather without all of
these.

moisture and weather?

6. What is the relationship between
moisture and weather?
Warm air over the
warm ocean has a lot
of moisture that can
result to precipitation.
7. How do air masses form?
An air mass is a
large body of air with
generally uniform
temperature and
humidity. The area
over which an air
mass originates is
what provides it's
characteristics.
7. How do air masses form?
Air masses are
formed by the uneven
heating and cooling of
Earth by the Sun.
Moisture in air
Dew drops
Moisture condenses as air cools.
This is because the cooler the air is,
the less water vapor it can hold.
Breathing Clouds
When you breathe out, you are filling
the air with water vapor. If the air is
very cold, the vapor will turn into lots
of tiny water droplets and your breath
looks "steamy".
8. How do storms form?
Tropical depression and storms
TROPICAL
DEPRESSION
Winds of 20-34 knots
(38 mph or less)
TROPICAL STORM
Winds of 35-64 knots
(39 to 73 mph)
Hurricane categories
Tornadoes
Tornadoes are ranked in the Enhanced Fujita
Tornado Scale according to wind speed.
EF-0: 65-85 mph winds
EF-1: 86-110 mph winds
EF-2: 111-135 mph winds
EF-3: 136-165 mph winds
EF-4: 166-200 mph winds
EF-5: 200 mph and above winds
