Cyclones🔥

* Cyclones are rapid inward air circulation around a low-pressure area. The air circulates in an anticlockwise direction in the Northern hemisphere and clockwise in the Southern hemisphere.

* Cyclones are usually accompanied by violent storms and bad weather.

* Cyclones represent circular fluid motion rotating in the same direction as the Earth. 

* The word Cyclone is derived from the Greek word Cyclos meaning the coils of a snake. It was coined by Henry Peddington because the tropical storms in the Bay of Bengal and the Arabian Sea appear like coiled serpents of the sea.

# Classification👇

* There are two types of cyclones:

Tropical cyclones; and

Extra Tropical cyclones (also called Temperate cyclones or middle latitude cyclones or Frontal cyclones or Wave Cyclones).

* The World Meteorological Organisation uses the term 'Tropical Cyclone’ to cover weather systems in which winds exceed ‘Gale Force’ (minimum of 63 km per hour).

# Tropical Cyclones👇

Tropical cyclones are violent storms that originate over oceans in tropical areas and move over to the coastal areas bringing about large scale destruction caused by violent winds, very heavy rainfall and storm surges.

Tropical Cyclones are one of the most devastating natural calamities in the world.

Tropical cyclones originate and intensify over warm tropical oceans.

# The conditions favourable for the formation and intensification of tropical storms are:

* Large sea surface with temperature higher than 27° C.

* Presence of the Coriolis force.

* Small variations in the vertical wind speed.

* A pre-existing weak low- pressure area or low-level-cyclonic circulation.

* Upper divergence above the sea level system.


# Extratropical cyclones are referred to as mid-latitude depressions, temperate cyclones, frontal depressions and wave cyclones.

These are active above the mid-latitudinal region between 35° and 65° latitude in both the hemispheres. The direction of movement is from west to east and more pronounced in the winter seasons. It is in these latitude zones the polar and tropical air masses meet and form fronts.

What can I learn/know right now in 10 minutes that will be useful for the rest of my life?

Believe me, I have the best advice for you!

Imagine, you are stuck somewhere and from last 3 hours you have a strong urge to go to toilet and get things done.

Finally, you get freedom and you start running towards toilet. You take your pants down furiously with the speed of light and acquire toilet seat with great satisfaction.

Ever in your life you must have gone through this.

At the time of taking pants down you feel the strongest urge to get things done however you have controlled yourself for last 3 hours. In those 10 seconds if in any case you don't take your pants down then definitely you will get into disaster.

That's same with your problems. They tend to appear much bigger when they are about to end. So, when ever your problems seem to get more complicated don't panic. Time has come to finish the problem but only thing you have to do is have patience and keep doing things in calm manner otherwise you know the d
Disaster.
