Saurabh moved to University of Tasmania, in October 2016 to commence his PhD in Quantitative Marine Science (QMS) at Institute of Marine and Antarctic Studies (IMAS), under the supervision of Dr. Helen Phillips (IMAS), Dr. Nathan Bindoff (IMAS) and Dr. Ming Feng (CSIRO). His work is on “The Impact of Recent Indian Ocean Warming on the Circulation, Water mass Distribution and Air-Sea Interaction in the Indian Ocean” is funded by National Environmental Science Programme (NESP) – Earth Systems and Climate Change (ESCC) Hub.
Prior to joining IMAS for his PhD Saurabh acquired his Bachelor’s in Aerospace Engineering in 2012 from The Aeronautical Society of India (AeSI). He is ardent about the fluid dynamics and thermodynamics that controls natural phenomena. For this reason he pursued his Master degree in Earth System Science & Technology from Indian Institute of Technology, Kharaghpur, India (IIT-KGP, India). During his masters he focused his research on the dynamics of meso-scale eddies in the Bay of Bengal and their impact on Atmospheric Properties.
Later he worked out a small project on the interdecadal variability of Indian Ocean warming and its associated mechanism in context of Interdecadal Pacific Oscillation and El-Niño.
THESIS: The Impact of Recent Indian Ocean Warming on the Circulation, Watermass Distribution and Air-Sea Interaction in the Indian Ocean
Suarabh's PhD project will combine the analysis of existing observations, reanalysis products, and high-resolution ocean circulation model output to determine patterns of change in heat and salt content resulting from the rapid increase in 0-700m heat content in the Indian Ocean during the recent hiatus period. He will also examine heat and salt balances to investigate the relationship between ocean heat and salinity changes and changes in atmospheric circulation including buoyancy fluxes and wind forcing in the region.
By using the CMIP5 group of simulations, the recent hiatus will be examined in the context of other hiatus events to contribute to addressing challenges in understanding decadal variability from regional scales to whole Indian Ocean. Decadal variability is a major focus of the climate community at present in order to predict climate fluctuations and also to distinguish the signals of global warming from natural variability in the ocean and atmosphere.
His work will address some key questions about the trend and variability of the Indo-Pacific exchanges in context of heat, salt and watermass distribution and its impact on ocean and atmospheric circulation in this region. It will also focus to address the question of missing hiatus heat in the Indian Ocean that drives changes in basin wide circulation.
