Ground fog

GROUND FOG Fog created when radiational cooling at the earth's surface lowers the temperature of the air near the ground to or below its initial dew point. Primarily takes place at night or early morning. Related term: radiation fog ...

Ground Fog Fog produced over the land by the cooling of the lower atmosphere as it comes in contact with the ground. Also known as radiation fog. Groung fog has little vertical extent (usually 20 feet or less).

Ground Fog: Fog of little vertical extent (usually 20 feet or less).
Grounded Ice: Ice that has run aground or is contact with the ground underneath it.

Ground Fog- fog with very little vertical extent (less than twenty feet deep).
Growing Season- the period of time between the last killing frost of spring and the first killing frost of autumn.

Ground fog See Radiation fog.
Growing degree-day A form of the degree-day used as a guide for crop planting and for estimating crop maturity dates.

ground fog—In the United States, a fog that conceals less than 0.6 of the sky and is not contiguous with the base of clouds.

Ground Fog- Shallow fog (less than twenty feet deep) produced over the land by the cooling of the lower atmosphere as it comes in contact with the ground. Also known as radiation fog.

Ground Fog - A shallow layer of fog (less than 20 feet thick) on the ground that reduces visibility more in the horizontal than in the vertical.

Radiation or ground fog - in mountain areas and cold pools often seen as valley fog. Radiation fog might be rather shallow over damp and wet ground after a rainy night and is sometimes called precipitation fog.

The net effect is that the satellite is virtually motionless with respect to an observer on the groundGFGround Fog- Fog produced over the land by the cooling of the lower atmosphere as it comes in contact with the ground.

It may also be called ground fog. RADIOSONDE An instrument attached to a weather balloon used to measure pressure, temperature, humidity, and winds aloft. Observations are made when the radiosonde is aloft and emits radio signals as it ascends.

6 of the sky is called ground fog. If fog is so shallow that it is not an obstruction to vision at a height of 6 ft above the surface, it is called simply shallow fog. In aviation weather observations fog is encoded F, and ground fog GF.

Obstructions to vision are listed in the Manual of Surface Observations (WBAN), Circular N, as follows: fog, ground fog, blowing snow, blowing sand, blowing dust, ice fog, haze, smoke, dust and blowing spray.

Radiation fog A ground-level fog formed by nocturnal radiational cooling of a humid air layer so that its relative humidity approaches 100 %; sometimes called ground fog.
Radio waves Long-wavelength, low-frequency electromagnetic waves.

Radiation fog Fog produced over land when radiational cooling reduces the air temperature to or below its dew point. It is also known as ground fog and valley fog.

Fog - Radiation: A form of fog caused by the cooling of moist air to below its dew point by the process of heat radiation. Radiation fog usually forms near the surface at night under clear skies and light wind conditions. Also known as ground fog.

Ground Fog: Fog that forms at ground level and does not reach the base of the clouds.
Ground Water: Water within the earth.
Gulf Stream: The Gulf Stream is a current of water which flows out from the Gulf of Mexico between Floriday and Cuba.
