1. Weather is the condition of the atmosphere at a particular time or place.
2. The weather is shaped into 4 main factors the air, the sun, water, the earth's movement.
1. Clouds are a visible mist of billions of water and ice particles floating in the sky.
2. Clouds form when air cools below its saturation point and causes water vapor to condense into tiny water droplets. The water droplets then form a cloud.
3. There are three families of clouds: cirrus, cumulus, and stratus. These are the latin names given to clouds in 1804. Cirrus means 'curl of hair', cumulus means 'heap', and stratus means 'layer'.
Cloud Type
Description
Possible Weather
Cirrus
"Cirrus" in latin means curl
and these clouds are named
because they resemble wisps
of curly hair.
Forms in winter and summer.
It depends on the speed and strength.
Altocumulus
Altocumulus clouds consist
of a thin sheet of white or
gray clouds that are broken
into bands, blobs, rolls or waves.
Altocumulus clouds can
sometimes mean that it
will rain or snow.
Nimbostratus
The word Nimbostratus means
"rainstorm" and "spread out" in Latin.
Rain and snow often accompany
the development of nimbostratus clouds.
Cumulus
Cumulus clouds are puffy,
low altitude clouds.
Cumulus clouds can cause rain,
although rain does not always
follow cumulus clouds.
Cumulonimbus
These clouds are named
because they are puffy
("cumulo") and because
they often are dark clouds
which cause rainstorms ("nimbus").
Cumulonimbus clouds can
produce rain showers,
snow showers, hail,
or even thunderstorms.

Weather Wise
Warm and Cold Fronts
Understanding Basic Concepts
- A cold front happens when a fast-moving mass of cold air hits a warm air mass.
- A warm front happens when a fast moving mass of warm air encounters a cold air mass, and rides up on top of it.
- The warm, humid air eventually rises high enough for water droplets and clouds to form, and rain to fall.
- The water vapour condenses to a lot of water droplets, which form tall clouds.

What is Weather?
http://oncampus.richmond.edu/academics/education/projects/webunits/weather/how.html1. Weather is the condition of the atmosphere at a particular time or place.
2. The weather is shaped into 4 main factors the air, the sun, water, the earth's movement.
Weather vs Climate
http://www.bom.gov.au/lam/climate/index.htm3. Climate is what you expect; Weather is what you get.
Climate is about long-term records, trends and averages;
Weather is the day to day experience.

A = Cold Front B = Warm Front
