Cyclonic circulation Atmospheric circulation associated with a cyclone (depression, low pressure area). It is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
cyclonic shear"Horizontal wind shear of such a nature that it contributes to the cyclonic vorticity of the flow, that is, it tends to produce cyclonic rotation of the individual air particles along the line of flow.
Cyclonic - Rotation in the same sense that the earth rotates, counter-clockwise in the Northern Hemisphere. Wind around a low; subgeostrophic.
Cyclonic: Air flow around the centre of a surface Low. In the Northern Hemisphere, this flow is counter-clockwise as seen from above. (In the Southern Hemisphere, it is clockwise.) Also, any rotation in the direction of the Earth's rotation.
Cyclonic Rotation - rotation in the same sense as the earth's rotation (i.e., counter-clockwise in the Northern Hemisphere as would be seen from above); the opposite of anticyclonic rotation ...
Cyclonic Flow - Winds blow in and counterclockwise about a cyclone (low) in the Northern Hemisphere and in and clockwise about a cyclone in the Southern Hemisphere.
CYCLONIC FLOW Winds that blow in and around a cyclone, that is counterclockwise in the Northern Hemisphere, clockwise in the Southern Hemisphere.

cyclonic - Having a sense of rotation about the local vertical the same as that of the earth's rotation: that is, as viewed from above, counterclockwise in the Northern Hemisphere, clockwise in the Southern Hemisphere, undefined at the equator; ...
Anticyclonic Rotation - Rotation in the opposite sense as the Earth's rotation, i.e., clockwise in the Northern Hemisphere as would be seen from above. The opposite of cyclonic rotation.
Anticyclonic- describes the movement of air around a high pressure; and rotation about the local vertical oppostie the earth's rotation.
Anticyclonic Gloom
Poor visibility, without precipitation, under an area of high pressure. The temperature inversion layer traps any pollution giving very dull conditions. Often seen in November.

LOW: A cyclonic storm that often forms along a front, around which the wind blows counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
METEOROLOGY: The study of atmospheric phenomena.
Large scale cyclonic spin is generated in this trough where the winds meet (aided by the spin of the earth). The monsoon trough then becomes a zone favorable for the birth of tropical cyclones.
A trough or cyclonic curvature maximum in the trade wind easterlies and it is not classified as a tropical cyclone. The wave may reach maximum amplitude in the lower middle troposphere.

Wave- A small cyclonic circulation in the early stages of development that moves along a cold front.
Weather- The conditions in the atmosphere at any given time.
Cutoff low Cyclonic circulation system that separates from the prevailing westerly airflow and therefore remains stationary.
D
Daily range of temperature The difference between the maximum and minimum temperatures for any given day.
AnticycloneA large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere, counterclockwise in the Southern HemisphereAnticyclonic RotationRotation in the opposite sense as the ...
Polar vortex - cyclonic motion near the pole. Very cold, especially in winter.
Radar - a radio device that calculates the distance to objects, such as storms, within its range.
HighAn area of high pressure, usually accompanied by anticyclonic and outward wind flow. Also known as an anticyclone. In Canada, a high is described as an area of high atmospheric pressure with a closed, clockwise movement of air.
It tends to remain stationary over its source area, with weak cyclonic circulation. There are no fronts associated with it. An example is the low that develops over southwestern United States and northwestern Mexico during the summer months.

Spotters should be especially wary of inflow bands that are curved in a manner suggesting cyclonic rotation; ...
Tropical Wave(formerly known as inverted trough) - A trough or cyclonic curvature maximum in the trade wind easterlies.
Areas of circulation also can develop at either end of a bow echo, which sometimes can lead to tornado formation - especially in the left (usually northern) end, where the circulation exhibits cyclonic rotation.
High: An area of high pressure: Anticyclonic.
High Pressure:Moves towards low pressure.
High Pressure: The winds are "Clockwise" (CW) in Northern Hemisphere. Move outward away from the center. Centrifugal force.
Rainbands are bands of showers and thunderstorms that spiral cyclonically toward the storm center. High wind gusts and heavy downpours often occur in individual rainbands, with relatively calm weather between bands.
Once one of the 8 compass point directions, from which the wind blows is allocated, the curvature of the flow is considered, and the directional letters are prefixed by either: A, anticyclonic or C, ...
cyclone—(1) An area of low atmospheric pressure which has a closed circulation that is cyclonic, i.e.
Most tornadoes are observed to rotate cyclonically (anticlockwise) but some rotate anticyclonically. Dust devils probably rotate in either direction, but I have seen no reports. They all occur when convection is active.
Cyclonically-curving inflow bands are visible in the upper portions of the photo, feeding into the updraft area.
Closed Low - A low pressure area with a distinct center of cyclonic circulation which can be completely encircled by one or more isobars or height contour lines.
Circulations of both influence one another with the two systems rotating around a common point between them in a cyclonic manner. If one system is larger than the other, that system will be more dominant of the two.
"Cyclogenesis" may refer to the birth of a cyclone or the intensification of cyclonic flow (counterclockwise circulation) around a low pressure system.
Suestado A storm with southeast gales, caused by intense cyclonic activity off the coasts of Argentina and Uruguay, which affects the southern part of the coast of Brazil in the winter.
Mesocyclone A vertical column of cyclonically rotating air that develops in the updraft of a severe thunderstorm cell; an early stage in the development of a tornado.
The hook is caused by precipitation drawn into a cyclonic spiral by the winds, and the associated notch in the echo is caused by precipitation-free, warm, moist air flowing into the storm.
high pressure system: area of maximum air pressure and anticyclonic air movement.
humidity: the measure of how much water there is in the air.
When seen from within several miles, many wall clouds exhibit rapid upward motion and cyclonic rotation. However, not all wall clouds rotate.
Cyclogenesis: Any development or intensification of a cyclonic circulation in the atmosphere.
Of the two, the right mover is most likely to weaken and dissipate (but on rare occasions can become a very severe anticyclonic-rotating storm), while the left mover is the one most likely to become a supercell.

They may indicate the strength of the inflow of moist air into the storm, and, hence, its potential severity. Spotters should be especially wary of inflow bands that are curved in a manner suggesting cyclonic rotation; ...
Depressions of the temperate zones were formerly often referred to as cyclones, but depression or low is now used to distinguish them from the tropical storms. The term "cyclonic depression" is still sometimes used for a depression, ...
and forecasting, it usually refers to the vertical component of rotation (i.e. rotation about a vertical axis) and is used most often in reference to synoptic-scale or mesoscale weather systems. By convention, positive values indicate cyclonic ...
The error in applying the hydrostatic equation to the atmosphere for cyclonic-scale motions is less than 0.01%. In extreme situations, the strong vertical accelerations in thunderstorms and mountain waves can be 1% of gravity.
Anticyclone An area of high atmospheric pressure which has a closed circulation that is anticyclonic (clockwise in northern hemisphere and counterclockwise in southern hemisphere).
synoptic scaleThe typical weather map scale that shows features such as high- and low-pressure areas and fronts over a distance spanning a continent. Also called the cyclonic scale. Typically ranging on the scale of 1000 to 2500 kilometers.
