  • Tropical Cyclone Maarutha has made landfall in Myanmar.
  • Heavy rainfall continues to be the main threat, which could cause flooding in that country.

Maarutha is the first named storm of the 2017 Northern Hemisphere tropical cyclone season.

  • The Joint Typhoon Warning Center said that Tropical Cyclone Maarutha had maximum sustained winds of 40 mph.
  • Maarutha is rapidly decaying, due to its interaction with land.
  • Maarutha is forecast to pass through capital city of Myanmar on April 17

Tropical Cyclone

  • A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain.
  • Tropical cyclones typically form over large bodies of relatively warm water.
  • They derive their energy through the evaporation of water from the ocean surface, which ultimately recondenses into clouds and rain.
  • The strong rotating winds of a tropical cyclone are a result of the conservation of angular momentum imparted by the Earth’s rotation as air flows inwards toward the axis of rotation.
  • Tropical cyclones are typically between 100 and 2,000 km (62 and 1,243 mi) in diameter.
  • Wind blowing counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
  • The opposite direction of circulation is due to the Coriolis effect.

What is the difference between Cyclone, Hurricane, Typhoon

  • Depending on its location and strength, a tropical cyclone is referred to by names such as hurricane, tropical storm, cyclonic storm, tropical depression, and simply cyclone.
  • A hurricane is a storm that occurs in the Atlantic Ocean and northeastern Pacific Ocean.
  • Typhoon occurs in the northwestern Pacific Ocean.
  • Cyclone occurs in the south Pacific or Indian Ocean.
