Middle latitudes
The latitude belt roughly between 35 and 60 North and South.

The weather of middle latitudes is dominated by broad-scale weather systems called Highs and Lows.
Highs and Lows are regions of relatively high and low surface air pressure, respectively.

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.

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.

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

The Arctic Oscillation is a pattern in which atmospheric pressure at polar and middle latitudes fluctuates between negative and positive phases.

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

JET STREAM An area of strong winds that are concentrated in a relatively narrow band in the upper troposphere of the middle latitudes and subtropical regions of the Northern and Southern Hemispheres.

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 middle latitudes of ...

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

In the oceans at low and middle latitudes permanent thermoclines start at 50-150 m below the surface and can extend down to more than 1000 m.

arctic oscillation an atmospheric circulation pattern in which the atmospheric pressure over the polar regions varies in opposition with that over middle latitudes (about 45 degrees N) on time scales ranging from weeks to decades; ...

Humid continental climate A relatively severe climate characteristic of broad continents in the middle latitudes between approximately 40 and 50º north latitude.

Low Clouds The bases of these clouds range from near the surface to about 6,500 feet in middle latitudes. These clouds are almost entirely of water, but the water may be supercooled at sub-freezing temperatures.

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

Westerlies The dominant westerly winds that blow in the middle latitudes 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.

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

GFS- Global Forecast System.

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

The height of the bases of these clouds ranges from 6,500 to 23,000 feet in middle latitudes. These clouds are primarily water; however, much of the water may be supercooled and the clouds can contain some ice crystals.

prevailing westerlies—The dominant west-to-east motion of the atmosphere, centered over middle latitudes 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 middle latitudes (35-65) of both hemispheres.

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 middle latitudes.

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