What is Cyclone Fani and how Fani got its name?
As we know that the India Meteorological Department (IMD) on 28 April issued a weather warning stating that Cyclone Fani would transform into a severe cyclonic storm. It may cause heavy rainfall in Kerala and light to moderate rainfall at north coastal parts like Tamil Nadu and coastal Andhra Pradesh.
What is Cyclone?
Cyclonic storm is a storm system in which the air rotates cyclonically. It is caused by atmospheric disturbances around a low-pressure area and is usually accompanied by violent storms and severe weather conditions. Let us tell you that the tropical cyclones that are intense are known as Hurricanes over the Atlantic Ocean and Typhoons over the Pacific Ocean.
Cyclone word is derived from Greek word cyclos which means coiling of snake. Basically, tropical cyclone is a deep low pressure area. From around the centre the strong winds spirals and pick up the speeds of 62 Kmph or more. In Northern-hemisphere these winds rotate counter-clockwise and in Southern Hemisphere clockwise. For example: dust devils, super cell thunderstorm, tornadoes, tropical cyclones, extra tropical cyclones etc.
What is Cyclone Fani?
A cyclone named Fani is a massive cyclonic formation over the south of Bay of Bengal which is expected to make landfall in Tamil Nadu, Kerala and Andhra Pradesh. Do you know the low-pressure belt of cyclone forms in Sri Lanka and then from there it turns north-west towards the southern Indian states. According to Mahesh Palawat, who works at Skymet Weather, this cyclone may cause hot winds from northeast and are expected to blow over Mumbai and adjoining areas in Maharashtra. Also, dust storms may likely to occur in Rajasthan as an impact; heat wave in Madhya Pradesh could follow.
The speed of the wind is expected to blow at 115 km/hour over southwest Bay of Bengal, off Sri Lanka, Tamil Nadu and Puducherry coasts on 29 April. Let us tell you that last year, Ockhi Cyclone hit parts of Kerala, Tamil Nadu and Sri Lanka. In Kerala that time around 80 fishermen were killed and around 140 people were reported missing. In November 2018, cyclone Gaja also made landfall in Nagapattinam's Vedaranyam block and killed around 46 people.
How Cyclone Fani got its name?
Cyclone Fani pronounced as Foni name was suggested by Bangladesh. It means 'Snake' or 'hood of snake'. Even the World Meteorological Organisation (WMO) has a well defined process to select the name of each cyclone.
How Cyclone originate?
On the basis of the speed of the wind cyclones are classified into five different categories from Category 1 to 5. According to the category of the cyclone the wind speed varies that is from 60 kilometres an hour to about 220 kmph and above.
When the speed of the wind around the low pressure area reach up to 62 kmph it is known as tropical cyclone and the name is assigned. When wind speed settles between 89 and 118 kmph, it turns into a Severe Cyclonic storm. When wind blows at a speed of about 119 to 221 kmph then it is known as Very Severe Cyclonic Storm and when the speed of the wind exceeds 221 kmph then the cyclone is known as Super Cyclonic Storm. Do you know that a fully matured cyclone develops a calm centre called Eye with a ring of hurricane winds around it?
So, now you may have come to know about the cyclone Fani and what is cyclone, how it originates etc.
