Transcript of Humidity and Saturation

All About Moisture in The Atmosphere
Humidity and Saturation
When a gas (cloud) holds the maximum amount of water vapor, it gets completely saturated and releases some of the water vapor. Releasing the water vapor creates humidity. Think of a sponge, when a sponge is not saturated with water it could hold more, when a sponge is saturated it can't hold anymore water and it is too saturated it will release the water
Adiabatic Temperature Changes
Without loosing or gaining heat and pressure is increased is under adiabatic conditions. When air is heated is becomes lighter and less dense. These molecules require energy to spread out and so the temperature drops even though no heat has been removed, this process is called adiabatic cooling.

Different Cloud Types and The Weather Associated with Each Type of Cloud
The Four Ways Clouds Form
High level clouds which form above 20,000 ft(6,000 meters) and are usually composed of ice crystals. High level clouds are typically thin and can create an array of colors the sun is low on the horizon.

Nimbus comes form the Latin word meaning "rain". These clouds typically form between 7,000 and 15,000 feet(2,100 to 4,600 meters) and bring steady precipitation begins to fall.

Clouds look like white fluffy cotton balls or heaps and show the vertical motion or thermal uplift of air taking place in the atmosphere. The level at which condensation and cloud formation begins is indicated by a flat cloud base, and it height will depend upon humidity of the rising air.

"Status" is Latin for layer or blanket. The clouds consist of a feature-less low layer that can cover the entire sky like a blanket, bringing generally gray and dull weather. That cloud base are usually only a few hundred feet above the ground.

Cirrus Clouds: which are like a thin sheet of ice and are wispy clouds which says there is going to be a weather change within 24 hours.
Cirrostratus clouds: which are also think sheet like clouds that cover the sky.
Cirocumulus clouds: are little white puffs which are in rows and may indicate a approaching hurricane.

Stratus clouds are gray clouds that cover the hole sky, which looks like fog just not close to the ground.
Stratocumuls clouds are gray puffy and low which forms with sky visible between the rows.
Nimbostratus clouds are dark grey which indicate a light or medium rain fall.


Mammatus clouds are low hanging droops from cumulonimbus with severe weather ahead.
Lenticular clouds look like discs or flying saucers created by a wave of wind.
Fog is a cloud of the ground made of water droplets floating above the ground.
Contrails are trails left behind jet aircrafts. When hot humid air from jets mixes with the air of low vapor pressure and low temperature.
