Question

what are the cyclone...
​

Answer 1

Answer:

In meteorology, a cyclone refers to any low pressure area with winds spiralling inwards. Cyclones rotate clockwise in the Southern Hemisphere and anti-clockwise in the Northern Hemisphere. ... Cyclones are also referred to as hurricanes and typhoons. They consist of the eye, eyewall and rainbands.....

━━━━━━━━━━━━━━━━━━━━━━━━━━

Cyclone are any large system of winds that circulates about a centre of low atmospheric pressure in a counterclockwise direction north of the Equator and in a clockwise direction to the south. Cyclonic winds move across nearly all regions of the Earth except the equatorial belt and are generally associated with rain or snow.Also occurring in much the same.

Additional information~

☆A cyclone is caused by atmospheric disturbances around a low-pressure area and is usually accompanied by violent storms and severe weather conditions. Intense tropical storms are called Hurricanes over theAtlantic Ocean and Typhoons over the Pacific Ocean.

☆The word Cyclone is derived from a Greek word cyclos, meaning coiling of snake. Tropical cyclone is a deep low pressure area wherein the central pressure falls 6 to 8 hPa (hectopascal) from the surroundings.

☆Strong winds spiral around the centre and pick up speeds of 62 kmph or more. These winds rotate counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Eye of a Cyclone~

A fully matured cyclone develops a calm centre called Eye with a ring of hurricane winds around it, possessing the following characteristics:-

1. Eye forms at the centre of Central Dense Overcast (CDO) region of storm.

2. Diameter of the Eye of a storm is about 10-50 km.

3. Eye is the cloud-free zone, surrounded by thick cloud walls.

4. Eye is surrounded by a 10-15 km thick wall of convective clouds, a zone of maximum wind.

5. Eye is the calm region with practically no rains.

6. Eye is warmer than the surrounding region.

7. Lowest surface pressure is observed at the Eye.

8. Eye is an indicative of very strong winds spiralling around the centre.

9. All cyclonic storms may not develop an Eye.

10. Sometimes, double Eye is also seen, which is indicative of very high intensity.

11. Eye wall is the most dangerous part of the storm.

12. Storm surge, torrential rains and high velocity winds are the associated features of Eye wall.
