When air is allowed to expand, it cools, and when it is compressed, it warm

When the temperature changes without adding hot of cold air it is called adiabatic temperature changes

When the air is unsaturated and the air warms up it is called dry adiabatic

When the has water vapor in it the adiabatic rate is slower then dry adiabatic rate

Orographic lifting

Orographic lifting is when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain.

It is when air is forced to go with the terrain

Front A front is a boundary between a cooling

body mass of hot air and cold air. A frontal wedging is ware the cold air is in the front

Convergence

Convergence is the natural heating and culling of the surface. Hot air rises cold air sinks

Hot air rises because it is less dens Cold air sinks because it is more

dens

Localclized Convection

Localized convection is when hot air rises in a pocket of les dens air and snicks as more dens cold air

Stability

Stable air stays in its original position, wile unstable air rises

the most stable conditions for the air is when air temperature actually increases with height it Is called a temperature inversion.

Condensation

For condensation to happen the air must be saturated to make dew, fog, or clouds

When air is saturated the water vapor condensates on to dust witch is called condensation nucli.

Classifications of clouds

Clouds are classified on the basis of there form and height.

Cirrus clouds are high White and thin. They can happen as patches or look like fluffy blankets in the sky.

Cumulus clouds are single round cloud masses with a flat base and a appearance that seams like it is rising.

Stratus clouds are the clouds that cover the sky completely with small or no brakes in it. With no individual cloud in it

High Clouds

The high clouds are called cirrocumulus cloud and there are three clouds that make up the high cloud they are the cirrus, cirrocumulus, and cirrostratus clouds.

It is 6000m in the air All high clouds are thin and white and

often made of ice crystals

Middle Clouds

The middle clouds also known as the altocumulus cloud they can change there form in different conditions

They are 2000, 6000 meters in the air They can be a Wight or gray with an

infrequent light snow or drizzle mar accompany the clouds

Low clouds

There is three types of low clouds stratus, stratocumulus, and nimbostratus.

The stratus cloud is a fog like layer that always cover the sky. When the cloud gets uneven it becomes an a stratocumulus cloud

A nimbostratus cloud is the clouds that produce precipitation

Clouds of Vertical Development

Clouds that don’t fit in the three height categories

The clouds with vertical development are filed with unstable air and all of them are related to another.

They can also produce rain

Fog caused by cooling

It starts when the earth cools off rapidly bye radiation

Rain a Snow

When the temperature is 4c snowflakes usually melt and continuo as rain drops

When the temperature is -5c ice crystals join into larger clumps and form a snow flake.

Sleet, Glaze and hail

Sleet is the fall of small particles of clear transparent ice.

Glaze also known as freezing rain it happens when rain becomes 0c and when it hits a surface I turns into ice.

Hail is produced in a cumulonimbus cloud it starts as a small ice pellets that grow by collecting super cooling water as they fall.
