6) Subtropical Cyclone Public Advisory (SPA): These advisories are issued when a subtropical storm is affecting or is forecasted to affect the U.S., our territories, or our installations.
Humid Subtropical Climate A climate generally located on the eastern side of a continent and characterized by hot, sultry summers and cool winters.
Hurricane A severe tropical cyclone having winds in excess of 64 knots (74 mi/hr).
SUBTROPICAL - Regions of the earth near but not in the tropics, such as near horse latitudes during the summer months, near 30 degrees north or south latitudes.
A subtropical cyclone is a weather system that has some characteristics of a tropical cyclone and some characteristics of an extratropical cyclone. They can form in a wide band of latitudes, from the equator to 50°.
the subtropical high pressure belt or horse latitudes
the westerlies or roaring forties
the belt of extratropical cyclones.
A semi-permanent, subtropical area of high pressure in the North Atlantic Ocean off the East Coast of North America that migrates east and west with varying central pressure. Depending on the season, it has different names.
Bermuda High: a subtropical anticyclone that occurs over the North Atlantic Ocean.
biosphere: the zone between the earth and the atmosphere in which most life forms reside.
Trade WindsPersistent tropical winds that blow from the subtropical high pressure centers towards the equatorial low.
STJSubtropical Jet - this jet stream is usually found between 20° and 30° latitude at altitudes between 12 and 14 km.
Polar JetMarked by a concentration of isotherms and strong vertical shear, this jet is the boundary between the polar air and the subtropical air.
North Atlantic Oscillation(Abbrev. NAO) - the NAO is a large-scale fluctuation in atmospheric pressure between the subtropical high pressure system located near the Azores in the Atlantic Ocean and the sub-polar low pressure system near Iceland ...
The poleward transport aloft is complemented by subsidence in the subtropical high pressure ridge and a surface return flow. The variability of this cell and the Walker cell is hypothesized to be a major factor in short-term climatic change.
sub-tropical cyclone - A cyclone in tropical or subtropical latitudes (from the equator to about 50°N) that has characteristics of both tropical cyclones and midlatitude (or extratropical) cyclones.
(Also called circumpolar westerlies, circumpolar whirl, countertrades, middle-latitude westerlies, polar westerlies, subpolar westerlies, subtropical westerlies, temperate westerlies, zonal westerlies, westerly belt, zonal winds.) Specifically, ...
Hurricanes originate over the tropical and subtropical North Atlantic and North Pacific oceans, where there is high humidity and light wind. These conditions prevail mostly in the summer and early fall.
Azores CurrentOne of the currents of the North Atlantic subtropical gyre.
AZORES HIGH A semi-permanent, subtropical area of high pressure in the North Atlantic Ocean that migrates east and west with varying central pressure. Depending on the season, it has different names.
Bermuda High: A semi-permanent, subtropical area of high pressure in the North Atlantic Ocean off the East Coast of North America that migrates east and west with varying central pressure. Depending on the season, it has different names.
Subtropical Jet Stream. 3. Jet Stream: Maximum. Jet Streak. Areas of highest wind speeds. 4. Jet Stream: Subtropical. Location. 18,000 feet to 40,000 feet. 5. Jet Stream: Wind speed: 50 mph to 400 mph. 6.
Alternate term for Bermuda High - a semi-permanent, subtropical area of high pressure in the North Atlantic Ocean off the East Coast of North America that migrates east and west with varying central pressure.
Bermuda High: The semi-permanent, subtropical anticyclone located over the western North Atlantic Ocean at about 30°N.
A semi-permanent subtropical high-pressure system over the North Atlantic Ocean brings in warm and humid air for many days or weeks at a time. It gets its name because it is sometimes centered near Bermuda. It contributes to U.S.
Horse Latitudes- subtropical regions where anticyclones produce settled weather.
Humidity- the amount of water vapor present in the air.
Hurricane- a tropical cyclone with sustained winds over seventy-four mph.
Trade Winds: Winds that divert from the subtropical high-pressure belts towards the intertropical convergence zone. They blow northeasterly in the Northern Hemisphere and southeasterly in the Southern Hemisphere.
Tropical Air
Mass of air which has been over tropical or subtropical regions for several days and which, therefore, has become fairly warm and moist.
Tropical Depression
Wind speed up to 33 knots (38 mph).
The zone of relatively low pressure, which lies between the subtropical anticyclones of the two hemispheres.
Equilibrium level ...
Waterspouts are most common over tropical or subtropical waters. The exact definition of waterspout is debatable. In most cases the term is reserved for small vortices over water that are not associated with storm-scale rotation (i.e.
Eventually, these storms turn northwestward around the subtropical high and migrate into higher latitudes. As a result, the Gulf of Mexico and East Coast of the United States are at risk to experience one or more hurricanes each year.
Specifically, it normally refers to a small, relatively weak rotating column of air over water beneath a Cb or towering cumulus cloud. Waterspouts are most common over tropical or subtropical waters.
As monsoons have come to be better understood, the definition has been broadened to include almost all of the phenomena associated with the annual weather cycle within the tropical and subtropical continents of Asia, ...
There is a weaker subtropical jet stream as well. Aircraft avoid the turbulence created by the jet streams, or else use them as favouring tailwinds. These winds were not well known in Geddes' time (see References).
[ In subtropical/tropical regions, 24 hour changes are usually used, to eliminate the influence of diurnal changes. ]
Reports of rainfall (or melted snowfall) should be in mm.
