Seasons on Earth
1. What is a weather map?
A weather map
displays
information of
various
meteorological
quantities at
various levels of
the atmosphere.
2. What are the common weather
map symbols?
Cold Front
• Strong winds and severe
thunderstorms.
• Heavy rain or snow may fall.
• It is fast moving.
2. What are the common weather map symbols?
Warm Front
• Scattered clouds if the
warm air is dry ( low
humidity).
• If the warm air is humid,
showers or light rain or
drizzle fall along the
front.
• This type of front moves
slow.
2. What are the common weather map symbols?
Stationary Front
• Water vapor in the warm
air condenses into rain,
snow, fog, or clouds.
• Rain can prolong for
many days causing
flooding.
• Can remain stalled over an
area for many days
2. What are the common weather map symbols?

• Cloudy, rainy or
snowy weather.
• Light to severe

Weather forecasting
involves a combination of
different factors like wind
direction, change in air
pressure, fronts,
temperature, humidity,
and others.

4. Why does it rain on top of the mountain?
Orographic lift occurs
when an air mass is
forced from a low
elevation to a higher
elevation as it moves over
rising terrain. As the air
mass gains altitude it
quickly cools down
adiabatically.

Adiabatic cooling is the process of
reducing heat through a change in air
pressure caused by volume expansion.
An increase in pressure results to an increase in
temperature.

across the United States?
