Dr Ambarish Karmalkar
- Visiting Research Associate
- Member of the Climate Systems and Policy research cluster
Academic Profile
Ambarish joined the School of Geography and the Environment (SoGE) in September 2010 as a postdoctoral researcher, working with Professor Mark New. Prior to this, he was employed as a postdoc at the University of Massachusetts (UMass) Amherst from September 2009. He received his Ph.D. in Geosciences from UMass Amherst. His thesis project involved studying climate change in Central America and Mexico using a regional climate model and his advisors were Prof. Raymond Bradley and Dr Henry Diaz (NOAA). He has a Masters degree in Astronomy from UMass Amherst and a MSc in Physics from the University of Mumbai.
Ambarish's research interests are in the field of present and past climatic changes and climate modelling. He is particularly interested in regional climate modelling, studies of climate model uncertainties and how model projections can be used in impacts assessment studies. He is also involved in a project with Dr Drew Shindell (NASA GISS), focusing on impacts of solar variability on the pre-industrial climate change. The prime focus of this work is to understand the effect of solar irradiance changes on the northern hemisphere sea level pressure (SLP) variability during the pre-industrial era with the help of model simulations and the SLP reconstructions.
Current Research
Currently, Ambarish is a postdoctoral researcher on the CARIBSAVE project with Professor Mark New and Dr Murray Simpson. He will be working on results from the regional climate model simulations to create regional climate change information for the island nations in the Caribbean. This work is in collaboration with partners in the Caribbean (University of West Indies, INSMET (Cuba)).
