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 three Indian national observational experiments under the Indian Climate Research Programme (ICRP) viz. the Bay of Bengal Monsoon Experiment(BOBMEX) carried out during July-August 1999, the Arabian Sea Monsoon Experiment(ARMEX) carried out over the west coast of India and Arabian Sea during 2002-2003, and ongoing Continental Tropical Convergence Zone (CTCZ) programme. 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, ARMEX and CTCZ 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,

  1. Chairman, Asian Fluid Mechanics Committee
  2. Chairman, Indian National Committee for Asian Congress of Fluid Mechanics
  3. Member, International Advisory Panel, Ministry of Earth Sciences, Govt. India
  4. Chairman, Technical Expert Committee for the National Facility for Airborne Research,IITM, Pune (ESSO)
  5. Member, Scientific Steering Committee for Continental Tropical Convergence Zone(CTCZ) Field Campaign under ICRP (MoES)
  6. Member, Programme Advisory Committee-Atmospheric Sciences, SERB (DST)
  7. Member, Scientific Advisory Committee, National Atmospheric Research Facility, Gadanki (ISRO)
  8. Member, Research Advisory Committee, Indian Institute of Tropical Meteorology, Pune(ESSO)
  9. Was a Member, Expert Panel on Fast Tack Young Scientist in Earth & Atmospheric Sciences (DST)
  10. Member, Editorial Board, Journal of Earth System Science
  11. Member, Editorial Board, Mausam
  12. Member, Sectional Committee (Earth & Planetary Sciences), Indian Academy of Sciences
  13. Chairman, the task team constituted by ISRO for Doppler Weather Radars Calibration
