Moisture, Clouds and precipitation
Adiabatic Temperature Changing and Expansion and Cooling.
• Temperature changes happen even though heat is not added or subtracted is adiabatic temperature.
• The first type of adiabatic is dry adiabatic, this is the cooling or heating of unsaturated air
• The second type is wet adiabatic, this is the cooling of saturated air and it moves slower than dry adiabatic.

Orographic Lifting
• This occurs when mountains act as barriers to air flow, forcing the air to ascend.

Frontal Wedging!!!!
• The area between warm and cold air is a front.
• A process that occurs at a front, dense air act like a road block.
• Less dense air rises.

Convergence
• The up rising of air that results from the air in the lower atmosphere flowing together is Convergence
• warm days, air flows from the ocean to the land along both coast of Florida

Localized Convective Lifting
• Unequal heating of earths surface warms a section of air that lowers the air density

Stability (Density Differnces & Syability and DAILY Weather
• Stable air stays in its position, when unstable air rises.
• Temperatures Conversion happens when air increases with height.

Condensation
• The air must be fully saturated to form any kind of condensation.
• Types of condensation is weather dew, fog, or clouds.

Types of clouds
• Clouds are described by their height and formed.
• There are different types of clouds
• Cirrus , Cumulus and Stratus.

High Clouds
• High clouds are often made up of ice crystals, they are thin and white as well.
• They are formed by low tempertaures, small amount of water vapor up high.

Middle Clouds
• Clouds appear to 2000-6000meters from ground.
• These Clouds put a blanket like across the sky that looks whiteish grey.

Low Clouds
• Low clouds cover a lot of the sky, kinda like fog.
• Low Clouds form from air rising up.
• Nimbostratus,Stratocumulus and stratus clouds are all types of low clouds.

Clouds of Vertical Development.
• Not all clouds fit in high low or middle clouds.
• Some clouds can form under the proper circumstance.

Fog
• There is nothing different from a fog and a cloud, the only difference is the method and place of formation.
• Fog is formed by radiation cooling.
• Fog is clouds that touch to the ground.

Cold Cloud Precipitation(Bergeron process)
• Bergeron Process is a theory that relates the formation of precipitation to supercooled clouds, Freezing nuclei
• Water is supercooled when it is below 0°C
• http://www.richhoffmanclass.com/chapter5.html
Warm Cloud Precipitation (collision-coalescence process)
• Supersaturated is with ice is greater than 100 percent relative humidity.
• Rain drop formation in warm clouds is a theory called Colluision-coalescence.

Rain & Snow.
• Drops of water that fall from the sky is called rain.
• When the temperature gets really cold the rain froze to a 6-sided ice crystal called snowflakes.

Sleet, Glaze and Hail
• Clear particles that fall from the sky is sleet.
• Glaze is when frozen rain falls to the ground.
• Hailstorms begin as ice pallets falling from the sky.
