“Due to upwelling caused by Nivar, Cyclone Burevi will have limited intensity,”-IMD.

The process in which cooler waters from lower ocean surfaces are pushed towards upper ocean surfaces.

  • In the absence of warm sea surface conditions, any cyclone, in this case Burevi, will not get enough fuel to intensify further while at sea.
  • Burevi will remain a cyclonic storm (wind speed 62 to 88 km/hr) till December 5, before it weakens into a deep depression.
