Updraft - A small-scale current of rising air. If the air is sufficiently moist, then the moisture condenses to become a cumulus cloud or an individual tower of a towering cumulus or Cb.
Updraft Base - Alternate term for a rain-free base.
Cutoff Low - A closed low which has become completely displaced (cut off) from basic westerly current, and moves independently of that current.

Rip Current
A strong, narrow current of surface water that flows seaward through the surf into deeper water. Waves approaching the shoreline create a water buildup which results in a return flow.
Ocean Currents
The world's oceans play an important role in global climate variability. Slow moving currents driven by differences in temperature and salinity link the major sources of heating and cooling across the ocean basins.

LOOP CURRENT - Name given to a few popular ocean currents. The Gulf loop current is a mild clockwise flow of water in the Gulf Of Mexico.
An upward current of air, usually within a thundercloud.
Veering Winds
Winds that shift in a clockwise direction.
California current The ocean current that flows southward along the west coast of the United States from about Washington to Baja California.
Cap cloud See Pileus cloud.
Eddy: swirling currents of air at variance with the main current.
Environmental lapse rate: the rate of decrease of air temperature with height, usually measured with a radiosonde.
Updraft: A current of air that has a marked upward vertical motion. Updrafts keep cloud particles suspended in the air.
The absorption of cosmic noise in the polar regions is very sensitive to the solar low-energy cosmic ray fluxRip CurrentA relatively small-scale surf-zone current moving away from the beach.
Air current Very generally, any moving stream of air. It has no particular technical connotation. Air density The mass density of a parcel of air expressed in units of mass per volume. Airlight formula See Koschmieder's law.
AIRMETAirman's Meteorological advisory (WA)AIVAviation Impact VariablesAlaska CurrentA North Pacific Ocean current flowing counterclockwise in the Gulf of Alaska.
Electromagnetic Current Meter
A device which measures current and water pressure variations. If deployed in shallow water current and pressure data can be converted to wave height, period and direction.
Smog A word currently used as a synonym for general air pollution. It was originally created by combining the words "smoke" and "fog." ...
ANABATIC WIND - A current of air which flows up a slope due to heating from the surface.
AN BOLT - Air force/Navy (AN) designated bolt with very high strength. Three marks on the head of the bolt identify it as an AN bolt.

A warm, swift ocean current that flows along the coast of the Eastern United States and makes Ireland, Great Britain, and the Scandinavian countries warmer than they would be otherwise.

It moves in the same direction as the basic current in which it is embedded, and may induce upward motion ahead of it, possibly contributing to thunderstorm development.
The properties that characterize the climate are thermal (temperatures of the surface air, water, land, and ice), kinetic (wind and ocean currents, together with associated vertical motions and the motions of air masses, aqueous humidity, ...

Currently, the most common measure of this period, “the average length of growing season,' is defined as the number of days between the average dates of the last killing frost (see frost) in spring and the first killing frost of autumn.
A closed low which has become completely displaced (cut off) from the basic westerly current which flows across Australia's southern oceans, and moves independently of that current (not including Tropical cyclones).
Because their water droplets are so small and light, it can take 21 days to fall 1,000 feet and wind currents can easily interrupt their descent. Liquid water falls as rain or drizzle. All raindrops form around particles of salt or dust.
Eastern Pacific hurricanes are actually Caribbean hurricanes that have crossed over the narrow land bridge and move northwestwards until they find the cold California Current and die.

jet stream- fast-moving currents of air reaching 180 mph (290 kmph ) in the troposphere - 30,000 to 35,000 feet up (9,144 to 10,668 meters) - that can strengthen and shift low-pressure systems.

Cutoff Low - A closed upper-level low which has become completely displaced (cut off) from basic westerly current, and moves independently of that current.
Fog forms at sea when warm air associated with a warm current drifts over a cold current and condensation takes place. Sometimes such fogs are drawn inland by low pressure, as often occurs on the Pacific coast of North America.
Analog Method - A statistical approach to weather forecasting in which current conditions are matched with records of similar past weather events with the idea that the succession of events in the past will be paralleled by current conditions.
gulf stream: ocean current flowing along the coast of the Eastern United States to Ireland, Great Britain, and the Scandivanian countries, making the latter three warmer than they otherwise would be.

Easterly Wave: Disruption in the form of trough in the east current of the tropics, which is more evident in high levels than in the surface analysis, and whose passage to the west is marked by an increase in nebulosity and showers.
Flash Flood Watch - Issued to indicate current or developing hydrologic conditions that are favorable for flash flooding in and close to the watch area, but the occurrence is neither certain or imminent.
Gulf Stream - A warm swift current in the Atlantic Ocean that flows from the Gulf of Mexico along the eastern coast of the United States and then northeast toward Europe.
Jet Stream
Flat tubular, quasi-horizontal, current of air generally near the tropopause, whose axis is along a line of maximum speed and which is characterized by great speeds and strong vertical and horizontal wind shears.
Although the position is part of a 21,000 year cycle, currently it occurs around January, when the earth is about 3 million miles closer to the sun than at aphelion. This term can be applied to any other celestial body in orbit around the sun.
El Niņo - Spanish for little boy. A change in the Pacific ocean current causing warm water to surface near South America. It usually occurs 2 or 3 times per decade and typically starts around Christmas time, henceforth its name.
SOLID STATE: A device which is able to control current without the use of moving parts or vacuum tubes.
SPAN: The absolute value of the differences between the upper and lower limits of an instrument's range.
Entrainment The mixing of environmental air into a preexisting air current or cloud so that the environmental air becomes part of the current or cloud.
Indeed, in the early days, the work was rather unfashionable, but is now required study given current concerns.
downdraft—A relative small scale downward current of air; often observed on the lee side of large objects restricting the smooth flow of the air or in precipitation areas in or near cumuliform clouds.
A type of instrument used for measuring wind speed by measuring the wind induced changes in the temperature of a metal wire that is heated by an electric current and cooled by convective heat loss.
