Advection fog forms as warmer, moist air moves over a cold ground. The air is cooled to saturation by the cold from the ground below cooling the air above

forms when fronts appear and when raindrops fall in warm and evaporate in cooler areas close to earths surface.

supercooled waterdroplets aka frost

This is fog that forms when rain is falling through cold air. This is common with a warm fronts but it can occur with cold fronts as well only if it's not moving too fast

This type of fog forms at night under clear skies with calm winds when heat absorbed by the earth's surface during the day is radiated into space

occurs when evaporation takes place into cold air lying over warmer water. cook

fog forms in the valley when the soil is moist from previous rainfall. As the skies clear solar energy exits earth and allow the temperature to cool near or at the dew point. This form deep fog, so dense it's sometimes called tule fog.

the temperature at which water vapor starts to condense out of the air, the temperature at which air becomes completely saturated. Above this temperature the moisture will stay in the air.

precipitation forms when water vapor freezes. IT IS NOT FROZEN RAIN. a cristilation of ice.

also called soft hail or hominy snow or granular snow or snow pellets, is precipitation that forms when supercooled water droplets in air are collected and freeze on falling snowflakes,

Snowmelt the flood of a river from heavy rain or melted snow.

most often falls from Stratus clouds which often have very low cloud bases, sometimes touching the ground to form fog

occurs when snowflakes only partially melt when they fall through a shallow layer of warm air. These slushy drops refreeze as they next fall through a deep layer of freezing air above the surface and bounce and freeze on impact.

Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze. Hailstones then grow by colliding with liquid water drops that freeze onto the hailstone's surface.

occurs when the layer of freezing air is so thin that the raindrops do not have enough time to freeze before reaching the ground. Instead, the water freezes on contact with the surface, creating a coating of ice on whatever the raindrops contact.

Term	Definition
advection	Advection fog forms as warmer, moist air moves over a cold ground. The air is cooled to saturation by the cold from the ground below cooling the air above
Frontal fog	forms when fronts appear and when raindrops fall in warm and evaporate in cooler areas close to earths surface.
freezing fog	supercooled waterdroplets aka frost
precipitation fog	This is fog that forms when rain is falling through cold air. This is common with a warm fronts but it can occur with cold fronts as well only if it's not moving too fast
Radiation fog	This type of fog forms at night under clear skies with calm winds when heat absorbed by the earth's surface during the day is radiated into space
steam fog	occurs when evaporation takes place into cold air lying over warmer water. cook
valley fog	fog forms in the valley when the soil is moist from previous rainfall. As the skies clear solar energy exits earth and allow the temperature to cool near or at the dew point. This form deep fog, so dense it's sometimes called tule fog.
what is dew point.	the temperature at which water vapor starts to condense out of the air, the temperature at which air becomes completely saturated. Above this temperature the moisture will stay in the air.
Snow	precipitation forms when water vapor freezes. IT IS NOT FROZEN RAIN. a cristilation of ice.
snow grains	also called soft hail or hominy snow or granular snow or snow pellets, is precipitation that forms when supercooled water droplets in air are collected and freeze on falling snowflakes,
frechet	Snowmelt the flood of a river from heavy rain or melted snow.
drizzle	most often falls from Stratus clouds which often have very low cloud bases, sometimes touching the ground to form fog
ice pellets/sleet	occurs when snowflakes only partially melt when they fall through a shallow layer of warm air. These slushy drops refreeze as they next fall through a deep layer of freezing air above the surface and bounce and freeze on impact.
hail formation	Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze. Hailstones then grow by colliding with liquid water drops that freeze onto the hailstone's surface.
graupel	Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze. Hailstones then grow by colliding with liquid water drops that freeze onto the hailstone's surface.
freezing rain	occurs when the layer of freezing air is so thin that the raindrops do not have enough time to freeze before reaching the ground. Instead, the water freezes on contact with the surface, creating a coating of ice on whatever the raindrops contact.
