The Southern Hemisphere mid-latitudes are considered to be the areas between about 30 degrees and 55 degrees latitude.
Mid-Latitudes- The areas in the northern and southern hemispheres between the tropics and the Arctic and Antarctic circles.
Millibar- A metric unit of atmospheric pressure. 1 mb = 100 Pa (pascal).
In mid-latitudes, the temperate zone, which is of most interest to us in NW Europe, the tropopause is highly variable, from cold to warm season, and from cold to warm air mass.
These clouds generally have bases above 20,000 feet in the mid-latitudes, and are classified as high clouds. They include all varieties of cirrus, cirrocumulus, and cirrostratus clouds.
See also North Wall WesterliesThe prevailing winds that blow from the west in the mid-latitudes.Wet Bulb Zero(Abbrev. WBZ) - the height where the wet-bulb temperature goes below 0°C.
It carries momentum, sensible heat, and potential heat from the tropics to the mid-latitudes (30 degrees). The poleward transport aloft is complemented by subsidence in the subtropical high pressure ridge and a surface return flow.
The Westerlies, which can be found at the mid-latitudes beneath the Ferrel circulation cell, likewise arise from the tendency of winds to move in a curved path on a rotating planet.
westerliesThe prevailing winds that blow from the west in the mid-latitudes.wet-bulb depressionThe difference in degrees between the air temperature (dry-bulb temperature) and the wet-bulb temperature.
In the mid-latitudes, cloud bases are usually found between 8,000 and 18,000 feet. A defining characteristic is that it often appears as a wavy billowy layer of cloud, giving it the nickname of "sheep" or "woolpack" clouds.
The lowest (major) layer of the atmosphere from the earth's surface up to the tropopause (at around 10 km in mid-latitudes) where most of the Earth?s weather occurs.
SPRING The season of the year which occurs as the sun approaches the summer solstice, and characterized by increasing temperatures in the mid-latitudes.
Westerlies: the prevailing winds that blow from the west in the mid-latitudes.
Wind chill equivalent temperature: the apparent temperature felt on the exposed human body owing to the combination of temperature and wind speed.
Jet Stream-A river of fast flowing air at high altitudes above the earth that generally flows from west to east over the mid-latitudes.
In the mid-latitudes, cloud bases are usually found between 20,000 to 30,000 feet, and it is the highest cloud that forms in the sky, except for the tops, or anvils, of cumulonimbus, which occasionally build to excessive heights.
Easterly waves are similar to waves in the mid-latitudes, except they are in the easterly trade-flow. Convergence associated with these waves creates thunderstorms that can ultimately reach hurricane strength.
The prevailing winds that blow from the west in the mid-latitudes.
Wet Bulb Zero ...
It is a major factor in determining climate through its influence on surface vegetation, the clouds, snow and ice, and soil moisture. The hydrologic cycle is responsible for 25-30% of the mid-latitudes' heat transport from the equatorial to polar ...
