Tropical cyclone is affected mainly by steering flow, Rossby drift and surface frictional effects. There are many models to predict the storm track. In this paper two thermodynamic parameters SWEAT and ACE are analyzed to observe the variation of these two parameters along the track of two cyclonic storms MALA and BIJLI over the Bay of Bengal. Peak ACE is found on the third day of the cyclonic ...

Affecting scores of people with seemingly insurmountable and unmanageable costs, tropical cyclones (TCs) are one of the most devastating extreme weather events. In this special issue, we highlight and summarize some of the recent studies that make use of detailed observations and high-resolution numerical models to analyze tropical cyclones from their genesis to post-landfall impacts. Focused a...

Aerosol distribution over the oceanic regions around the Indian subcontinent and its seasonal and interannual variabilities are studied using the aerosol optical depth (AOD) derived from NOAA-14 and NOAA-16 AVHRR data for the period of November 1995–December 2003. The air-mass types over this region during the Asian summer monsoon season (June–September) are significantly different from those d...


 Daily variations of surface and thermodynamical parameters in the vicinity eastern end monsoon trough located over northwest adjoining westcentral Bay Bengal have been studied. A model sequence for strengthening/weakening head Bengal, which is seat cyclogenesis during southwest monsoon, has proposed. Monsoon activity sea seems to possess a 4 day cycle. The primary forcing activation appe...

West Bengal is the fourth most populated state situated in the Eastern Region of India, 82 million people stay in the State. It is 2.7% of India's area but about 7.8% of the country's population. This state ranks first in terms of density of 904 per sq. km as per the 2001 census. The boundaries of the state are Nepal, Bhutan and the Sikkim on the North, Goalpara district of Assam and Bangladesh...

This paper describes the near surface characteristics and vertical variations based on the observations made at 17.5◦N and 89◦E from ORV Sagar Kanya in the north Bay of Bengal during the Bay of Bengal Monsoon Experiment (BOBMEX) carried out in July –August 1999. BOBMEX captured both the active and weak phases of convection. SST remained above the convection threshold throughout the BOBMEX. Whil...

In order to examine the influence of discharge from different rivers from peninsular India and urban sewage on intensity and dissemination of heterotrophic, indicator and pathogenic bacteria, a study was carried out during peak discharge period along coastal Bay of Bengal. The coastal Bay received freshwater inputs from the river Ganges while Godavari and Krishna contributed to the south. Contr...
