Upwelling

Upwelling the transport of deeper water to shallow levels
One oceanic process altered during an El Niño year is upwelling, which is the rising of deeper colder water to shallower depths.

upwelling"An ascending motion of subsurface water by which water from deeper layers is brought into the surface layer and is removed from the area of upwelling by divergent horizontal flow.

Upwelling Radiation - the component of radiation (either reflected solar or emitted terrestrial) directed upward from the earth's surface; opposite of downwelling radiation ...

Upwelling
The rise to the surface of cold, deep ocean waters.

UPWELLING
The process by which water rises from a lower to a higher depth, usually as a result of divergence and offshore currents. It influences climate by bringing colder, more nutrient-rich water to the surface.

Upwelling
The rise of colder, deep ocean waters along a coast due to the movement of surface water away from the coast.

Upwelling The process by which cold waters from the depths of a lake or ocean rise to the surface.

Upwelling - A rising-up of colder water.
Veering - Clockwise shifting of the winds with time or distance.
Vorticity - Spin of the air indicating rotation. Positive vorticity is cyclonic flow, while negative vorticity is anticyclonic.

UPWELLING: The rising of cold water from the deeper areas of the ocean to the surface. This phenomena often occurs along the California coast during the spring and summer.

Upwelling - In ocean dynamics, the upward motion of sub-surface water toward the surface of the ocean. This is often a source of cold, nutrient-rich water. Strong upwelling occurs along the equator where easterly winds are present.

Upwelling The rising of water (usually cold) toward the surface from the deeper regions of a body of water.
Urban heat island The increased air temperatures in urban areas as contrasted to the cooler surrounding rural areas.

Upwelling The upward circulation of cold, nutrient-rich bottom water toward the ocean surface.

Valley breeze A shallow, upslope flow of air that develops during daylight hours within mountain valleys.

upwelling The vertical motion of water in the ocean by which subsurface water of lower temperature and greater density moves toward the surface of the ocean.

upwelling and downwelling radiative transfer through atmospheric layers
upwards transport of heat by convection (especially important in the lower troposphere).

UPWELLING - A rise in cold ocean water from greater depths. Common where seasonal winds affect offshore currents, such as off California.

shortwave net radiationThe difference between upwelling and downwelling broadband shortwave radiation.shortwave radianceA measure of the intrinsic radiant energy flux intensity, at wavelengths between 0.

It consists of both upwelling and downwelling components. Compare with terrestrial radiation.ATMPOn a buoy report, the air temperature (Celsius).

Effective Terrestrial RadiationThe difference between upwelling infrared or terrestrial radiation emitted from the earth and the downwelling infrared radiation from the atmosphere Effective TopographyThe topography as seen by an approaching ...

Along the west coast of South America, southerly winds promote the upwelling of cold, nutrient-rich water that sustains large fish populations, that sustain abundant sea birds, whose droppings support the fertilizer industry.

The winds blowing from west to east move the warm waters eastward, when this occurs, The UPWELLING of the colder water rich in nutrients from the depths of the Pacific Ocean weakens, or does not occur at all.

When clouds are present, they form over the upwelling parts of the roll circulation. Called cloud streets, they are a good measure of roll wavelength.

When this warming occurs the usual upwelling of cold, nutrient rich deep ocean water is significantly reduced. Sometimes an extremely warm event can develop that lasts for much longer time periods.

There is considerable upwelling of the colder subsurface waters due to the prevailing southerly winds. Dominant weather in this area includes coastal fog and low clouds.

A strong, cold, downslope wind.
