CYCLONE BUREVI

Subject: Geography

Context : The Deep Depression over southwest Bay of Bengal moved west-north westwards with a speed of 09 kmph during past six hours, intensified into Cyclonic Storm ‘Burevi’.

Concept:

• The India Meteorological Department (IMD) announced that a cyclone brewing in the Bay of Bengal is likely to affect Tamil Nadu and Kerala, less than a week after cyclone Nivar wreaked havoc in the southern states.
• The cyclone will cross the Sri Lanka coast on December 2 and bring heavy rain over Tamil Nadu and Kerala.
• Due to upwelling caused by nivarcyclone , there is high possibility that Burevi cyclone will not strengthen beyond the intensity of cyclonic storm.
• When consecutive cyclonic systems develop in the same region of the ocean , the predecessor system leads to upwelling in ocean that is cooler waters from lower part of teh ocean are pushed towards the surface part of the ocean which leads to decrease in temperature.
• In the absence of warm sea conditions , any cyclone will not have enough fuel to intensify beyond cyclonic storm.
• IMD has predicted that Burevi will remain as a cyclonic storm till December 5, before it weakens into deep depression.
