Rapid Intensification made AMPHAN a Super Cyclone

The Cyclone ‘Amphan’ has intensified from a severe cyclonic storm to a Super Cyclone. This has happened in less than 40 hours.

Highlights

The rapid intensification of Amphan into a Super Cyclone is mainly because of rapid warming up of Bay of Bengal. The following are the main reasons that led to rapid intensification of the cyclone

  • High Sea Surface Temperature
  • Enough Moisture in the middle layers of the atmosphere
  • Low Vertical Shear Winds

When does Rapid Intensification occur?

Rapid Intensification of a cyclone occurs when there is increase of sustained winds that blow at a speed of 55 km/hr. Rapid Intensification is common in case of hurricanes, so far not in case of cyclones.

Difference between hurricanes and cyclones

Both hurricanes and cyclones are tropical cyclones. They are named differently based on their region of formation. Cyclones are formed in South Pacific and Indian Oceans. On the other hand, hurricanes are formed in North Atlantic, Eastern and Central Pacific Oceans.

History

Scientists believe that Rapid Intensification might become common among the cyclones in the future. Earlier, Rapid Intensification was observed in cyclone Vayu. However, the main issue is that there is lack of data about rapid intensification rates of cyclone in India.

The two other major Super Cyclones that hit India were Cyclone Gonu in 2007 and Cyclone Kyarr in 2019.

A new species “Troglomyces twitteri” discovered

A new parasitic fungus was discovered by a Denmark biologist called “Troglomyces twitteri”. The fungus has been named after Twitter as it was discovered in Twitter

Discovery

The biologist Sofia Reboleira of University of Copenhagen, Denmark founded the species. The image was posted in Twitter by an entomologist 1n 2018. He was sending millipede photos to people who had tweeted him. The photos were being sent for polling purpose.

About the new species

The photo of the millipede had tiny dots that looked like Fungi. The Fungi belongs to the order called Laboulbeniales. These are fungi that attack millipedes and insects. They look like larvae.

There are more than 30 different species that attack the millipedes.

Millipedes

The Millipedes are arthropods. They have two pairs of jointed legs. They feed on decaying leaves and dead matter. Thus, in a way they help in decomposition process. They cause trouble in greenhouses where they cause severe damages to seedlings. They are harmless to humans.
