Water Cycle & Precipitation

Is the movement of water among the great global reservoirs

• A change of state from solid to liquid or liquid to gas absorbs latent heat from the surroundings which means latent heat is released when clouds form and absorbed when water evaporates from the planets surface

Net radiation energy

Energy

Is a measure of the water vapour in the air - The max quantity of moisture that air can hold increases with air temperature - warm air holds more moisture than cool air

Is the temperature at which a mass of air holds its maximum capacity of water vapour

• Is a change in temperature within a gas that occurs only as a result of change in pressure

Because the atmospheric pressure decreases with altitude, if you lift a parcel of air away from the surface, the pressure in the parcel decreases

Dew point temperatures, and the need for water droplets to form on a solid surface

Are composed of water droplets and ice crystals. - They also contain tiny supercooled water droplets

Microscopic particles known as cloud condensation nuclei

Cirro

Alto

strato/stratus

Cumu

Stratiform

Cumuliform

Cirroform

Nimbo

Is a cloud at the surface instead of the atmosphere

Forms when a surface cools the air directly above, often forming night

Is when a cold air descends down a valley like a radiation fog

Forms when air migrates to a place where the conditions allow saturation to occur which happens along coastlines and is called sea fog

snow or ice
