Considered the climate of the middle latitudes. TEMPERATURE The measure of molecular motion or the degree of heat of a substance. It is measured on an arbitrary scale from absolute zero, where the molecules theoretically stop moving. It is also the degree of hotness or coldness.

They are most commonly seen during winter in the middle latitudes and are exclusively associated with cirriform clouds. They are also known as mock suns. Partial Beam FillingA limitation of the rainfall estimation techniques used by NEXRAD.

Main Phase: Of a geomagnetic storm, that period when the hori- zontal magnetic field at middle latitudes is generally decreasing.
Recovery Phase: Of a geomagnetic storm, that period when the depressed northward field component returns to normal levels.

AOArctic Oscillation - the Arctic Oscillation is a pattern in which atmospheric pressure at polar and ~ fluctuates between negative and positive phases.

The Arctic Oscillation is a pattern in which atmospheric pressure at polar and ~ fluctuates between negative and positive phases. The negative phase brings higher-than-normal pressure over the polar region and lower-than-normal pressure at about 45 degrees north latitude.

Prevailing Westerlies Winds in the ~ (approximately 30 to 60) that generally blow from west to east.

circumpolar whirl, countertrades, middle-latitude westerlies, polar westerlies, subpolar westerlies, subtropical westerlies, temperate westerlies, zonal westerlies, westerly belt, zonal winds.) Specifically, the dominant west-to-east motion of the atmosphere, centered over the ~ of ...

an atmospheric circulation pattern in which the atmospheric pressure over the polar regions varies in opposition with that over ~ (about 45 degrees N) on time scales ranging from weeks to decades; the oscillation extends through the depth of the troposphere, and from January to March, ...

In time, hurricanes move into the ~ and are driven northeastward by the westerlies, occasionally merging with midlatitude frontal systems.

In the oceans at low and ~ permanent thermoclines start at 50-150 m below the surface and can extend down to more than 1000 m. In polar regions the thermocline is generally absent since the ocean surface is covered with ice in winter and solar radiation is small in summer.

Humid continental climate A relatively severe climate characteristic of broad continents in the ~ between approximately 40 and 50º north latitude. This climate is not found in the southern hemisphere, where the ~ are dominated by the oceans.

Low Clouds The bases of these clouds range from near the surface to about 6,500 feet in ~. These clouds are almost entirely of water, but the water may be supercooled at sub-freezing temperatures. Low clouds at sub-freezing temperatures can also contain snow and ice particles.

Westerlies The dominant westerly winds that blow in the ~ on the poleward side of the subtropical high pressure areas.
Wet-bulb temperature The lowest temperature that can be obtained by evaporating water into the air.
Whirlwinds See Dust devils.

A zonal wind with a constant wind speed in the upper troposphere in the ~ is an example of a geostrophic wind.

GFS- Global Forecast System. This is a synoptic model that has output for several days into the future and was previously known as MRF (Medium Range Forecast).

It is associated with the location and motion of the high and low pressure areas of the ~, and therefore, is variable in position, elevation, and wind speed.

These factors also give rise to seasonal monsoons, jet streams in the upper atmosphere, and other complications, as well as the giant eddies (cyclones and anticyclones) in ~.
The diagrams also show major pressure and wind zones. As we move from the equator towards the poles they are: ...

Middle Clouds: In the middle family are the altostratus, altocumulus, and nimbostratus clouds. The height of the bases of these clouds ranges from 6,500 to 23,000 feet in ~.

prevailing westerlies—The dominant west-to-east motion of the atmosphere, centered over ~ of both hemispheres.
prevailing wind—Direction from which the wind blows most frequently.

westerlies: the dominant west-to-east motion of the atmosphere centered over the ~ (35-65) of both hemispheres.

The dominant west-to-east motion of the atmosphere, centered over the ~ of both hemispheres.
The horizontal movement of air, relative to the earth's surface.
Wind Chill ...

The formulae use observations either of the depletion of the solar beam, temperature lowering in ~, or the quantity of solid matter dispersed as dust.
