On the 29 September 1971, a cyclonic storm of severe intensity passed very close to Calcutta. Calcutta reported a record pressure deficiency of 26 rob at 1200 GMT of 29th, when the storm was close to Calcutta. Upper air soundings of Calcutta were available up to fairly high levels for all hours of observations during the life of the storm except for the evening of the. 29th when the sounding terminated at 362 mb. The vertical structure of the storm is characterised by a warm core with temperature anomalies exceeding 8°C centred around the 250 mb level. There is evldence of a cold area at 125 mb and 100 mb levels where the negative anomalies of temperature were lower than 8°C.
