What are cyclonic and anticyclonic winds?

When the wind swirls clockwise in the northern hemisphere or counter-clockwise in the southern hemisphere, it is called anticyclonic flow. An example of cyclonic flow is the flow around a low pressure area while an example of anticyclonic flow is the flow around a high pressure area. A hurricane is a cyclone.
A.

Are Cyclones clockwise?

There are a number of structural characteristics common to all cyclones. Because of the Coriolis effect, the wind flow around a large cyclone is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
  • What kind of devastation can Cyclones cause?

    Cyclone danger and impacts. Tropical Cyclones are dangerous because they produce destructive winds, heavy rainfall with flooding and damaging storm surges that can cause inundation of low-lying coastal areas.
  • What do they call hurricanes in the Indian Ocean?

    In the Atlantic and northern Pacific, the storms are called "hurricanes," after the Caribbean god of evil, named Hurrican. In the northwestern Pacific, the same powerful storms are called "typhoons." In the southeastern Indian Ocean and southwestern Pacific, they are called "severe tropical cyclones."
  • What is the difference between a tornado and a cyclone?

    What is the difference between cyclone, hurricane, tornado and twister? Technically, a cyclone is any kind of circular wind storm. But now, it is only used to describe a strong tropical storm found off of the coast of India. Hurricanes and Typhoons are the same thing, but in different places.
B.

Are tornadoes clockwise or counterclockwise?

The sense of rotation is usually the opposite. Most tornadoes (but not all!) rotate cyclonically, which is counterclockwise in the northern hemisphere and clockwise south of the equator.
  • Are tornadoes high or low pressure?

    A tornado is not necessarily visible; however, the intense low pressure caused by the high wind speeds (as described by Bernoulli's principle) and rapid rotation (due to cyclostrophic balance) usually cause water vapor in the air to condense into cloud droplets due to adiabatic cooling.
  • Is there precipitation in a tornado?

    Tornado Characteristics. Time of day during which tornadoes are most likely to occur is mid-afternoon, generally 3–7 P.M. Precipitation associated with the tornado usually occurs first as rain just preceding the storm, frequently with hail, and as a heavy downpour immediately to the side of the tornado's path.
  • How fast can a tornado can spin?

    The damage from tornadoes comes from the strong winds they contain. It is generally believed that tornadic wind speeds can be as high as 300 mph in the most violent tornadoes.
C.

What does it mean to be cyclonic?

Meteorology. a. An atmospheric system characterized by the rapid inward circulation of air masses about a low-pressure center, usually accompanied by stormy, often destructive weather. Cyclones circulate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
  • What is a cyclonic vacuum?

    One recent vacuum-cleaner variation is the so-called "cyclone vacuum." This machine, developed in the 1980s by James Dyson, doesn't have a traditional bag or filter system. Instead, it sends the air stream through one or more cylinders, along a high-speed spiral path.
  • How does cyclonic precipitation occur?

    As the air rises, it cools. Water vapour in the air condenses into clouds and precipitation. This type of precipitation is common in the Prairies and Ontario. Cyclonic or Frontal precipitation results when the leading edge of a warm, moist air mass (warm front) meets a cool and dry air mass (cold front).
  • How is visibility measured in weather?

    Visibility. In meteorology, visibility is a measure of the distance at which an object or light can be clearly discerned. It is reported within surface weather observations and METAR code either in meters or statute miles, depending upon the country. Visibility affects all forms of traffic: roads, sailing and aviation.
