Related facts:

  • Indian scientists have discovered a hitherto unknown effect of the tropical weather phenomenon known as Madden-Julian Oscillation.
  • It is an eastward moving disturbance of clouds, rainfall, wind and pressure. It circles the planet along the tropical belt in 30-80 days.
  • During its global ride, it intensifies over three regions – the eastern Indian Ocean, south of the maritime continent and the western Pacific Ocean and transfers a part of its energy to the underlying ocean.
  • Madden-Julian Oscillation (MJO) plays an important role in determining the fate of the Indian summer monsoon.
  • The waves generated by the MJO in the Indian Ocean can add to the impacts of the cyclones.
