 Brief Profile of Professional Career


               His engineering background and opting to work in atmospheric sciences enabled him to bring a unique combination of expertise to the research in the field of atmospheric Sciences in India. He has wide research interests that include tropical convection, ocean-atmosphere interactions, clouds, boundary layer, flow turbulence, dynamical chaos and tropical intraseasonal oscillation. G S Bhat has carried out laboratory experiments, field experiments over land and ocean, theoretical studies and data analysis. He was the Principal Investigator for the atmospheric component in the first two Indian national observational experiment under the Indian Climate Research Programme (ICRP) viz. the Bay of Bengal Monsoon Experiment (BOBMEX) carried out during July-August 1999 and the Arabian Sea Monsoon Experiment (ARMEX), carried out over the west coast of India and Arabian Sea during 2002-2003. Crucial data has been successfully collected from research ships using the state of the art instruments under the raging monsoon conditions over the Bay of Bengal and Arabian Sea. BOBMEX and ARMEX have added a different dimension to the kind of research work done from the country in the areas of atmospheric sciences and oceanography and have drawn the attention of international community.


He is/was a member of several committees including,


(i)              Chairman, Indian National Committee for Asian Congress of Fluid Mechanics

(ii)             Chairman, the task team constituted by ISRO for Doppler Weather Radars


(iii)     Member, Scientific Steering Committee for Continental Tropical Convergence Zone (CTCZ)  Field Campaign under ICRP (DST)

(iv)    Was a Member, Expert Panel on Fast Tack Young Scientist in Earth & Atmospheric Sciences (DST)

(v)      Vice-Chairman, Asian Fluid Mechanics Committee

(vi)     Member, Programme Advisory Committee – Atmospheric Sciences (DST)
