HOW DOES CYCLONE TAKES PLACE?

Question

HOW ARE CYCLONES FORMED?

Answer 1

It is the same thing as a tornado. Scientists do not completely understand how tornadoes form. They do know that they often form inside severe thunderstorms that have golf ball sized hail or larger. Tornadoes sometimes occur in a type of severe thunderstorm called a supercell. These supercells are well organized, long lasting thunderstorms with warm moist air spiraling upwards. They are generated in much the same way as severe thunderstorms, except  they need a few additional conditions. Atmospheric scientists have discovered that for tornadoes the updraft  needs to be halted for a while, by a layer of warm air just above the ground. As a result, energy              

inside the storm builds up. Once the updraft is released it explodes upward, like a bullet fired from a gun. Usually, the layer of warm air is overcome when the ground becomes warm enough  from sunshine. That is why most tornadoes happen in the afternoon,A tornado usually is found between the strong updraft and the down draft . All strong tornadoes form in a low over hanging cloud that lies just below the thunderstorm. This is called a wall cloud. The spiral inside the thunderstorm is caused by a low level south or southeast wind being pushed upward. This wind meets with a stronger upper wind that comes from the west or southwest. The cross each other's path, causing a spin. Scientists do not understand what causes the 2-to- 6 mile wide(3-10km) spiral to become narrow and drop out of the sky. The narrowing is similar to the way an ice skater spins. It she pulls her arms in, she will spin faster... Still, there is no explanation as to what causes a tornado to descend out of the cloud to the ground. That is why scientists still chase tornadoes. NOW HOW THEY ACTUALLY FORM. The difference in the wind speed or direction between the ground and the atmosphere about 6,000 feet (1,830km) off the ground causes eddies (circular spinning of air). As an eddy moves toward the center of the storm, the up draft sucks it upward. The eddy is tilted upward and stretched. The eddy becomes vertical. Out of this eddy, the tornado develops below the cloud. The tornado is smaller than the eddy. Scientists are still trying to find out why a gently circulating eddy produces a rapidly spinning tornado. Sorry for the long explanation.  

Answer 2

which place is low air circulation that place fill by air forcely.that is called cyclone.normally the cyclones are formed in sea.because the sea have lot of free spaces.

Answer 3

cyclone, just like any other storm, starts in what we call a depression. an atmospheric condition wherein low pressure is formed. but in cylone it is normally formed above a large body of water, say ocean, because in here large amount of warm air is produced because of the warming of the ocean. when this warm air develops, it goes upward (as the principle that hot air rises and cold air stays below). and so, as it goes up, it sucks the surrounding air below to  fill in the the vacant space .this acts like a big vacuum cleaner. and so the process goes on until this difference in pressure is stabilised. now ,the movement of this cyclone  from one place to another is due to the rotation of earth on its orbit.. did i answer it right?

Answer 4

it usally takes place from the sea

Answer 5

A cyclone is an area that is surrounded by a wind system and has a low atmospheric pressure. In the southern hemisphere, the winds blow in a clockwise direction. An area that has a high atmospheric pressure and winds blowing in a counterclockwise direction is known as an anticyclone. In the northern hemisphere, a cyclone's winds blow counterclockwise and an anticyclone's winds blow clockwise.

Subtropical cyclones are very similar to extra tropical and tropical cyclones but unlike most cyclones, subtropical cyclones can occur at any time of year. They are hybrid storms and it is very hard to find consistent characteristics amoung them. The maximum wind intensity they can have is 420 km or 300 mi from the center of the cyclone. Subtropical cyclones have large centers, sometimes as big as 140 km in diameter. In the center there isn't much rain or pressure. They develop from cold-upper-level polar troughs. Sometimes the bottom portion of an upper-level trough cuts off and forms an upper-level-cold-core low. When this reaches the surface, it becomes a subtropical cyclone. They have a very high degree of symmetry and have high levels of persistence. Sub-tropical cyclones don't disappear; instead they hook on to another large storm. Many storms become subtropical cyclones as they decline which brings about many changes such as more rain and increased temperatures. Though subtropical cyclones aren't dangerous by themselves, they need to be watched in case they develop in to something more dangerous, like a tropical cyclone.

A typhoon is a tropical cyclone that has winds of seventy-four miles per hour or more, and forms in the West Pacific Ocean. In order for a typhoon to form, there are several necessary things that must be in place. There must be warm waters, in order to fuel the heat engine of the typhoo; an atmosphere that will cool fast enough with height, so that it is potentially unstable to moist convection; relatively moist layers near the mid-troposphere (3mi); a minimum distance of at least 300 miles (500km) from the equater; a pre-existing near-surface disturbance; and low values (less than about 23mph [10m/s]) of vertical wind shear between the surface and the upper troposphere. Vertical wind sphere is the magnitude of wind change with height. Typhoons begin near the equater and move westward, gathering intensity and size. They advance slowly, usually at about 10 to 15 miles (16-24 km) per hour. But the circular winds around the center are very strong, ofter reaching speeds of 150 miles (240 km) per hour. Typhoon season runs from the first of July through the thirtieth of November.
