Research Interests

- Monsoon intraseasonal Variability and extended range prediction
- Monsoon-ENSO relationship
- Large scale air-sea interactions in the tropics

Presently I am working as post-doctoral researcher at LMD in the framework of the European Union project ‘ENSEMBLES’. The intraseasonal variability associated with the Asian summer monsoon as simulated by seven European coupled general circulation models (CGCMs) are analysed and assessed against observations. The model assessment focuses on the spatial and seasonal variations associated of the monsoon intraseasonal variability of convection, their large-scale organization, propagation characteristics, the air-sea coupling, their deterministic predictability and implications on seasonal predictability.

I did my PhD under the supervision of Prof. B.N. Goswami. My Doctoral thesis examines the predictability of Indian summer monsoon from intraseasonal to seasonal time scales. A new convention to isolate the predictable component of interannual variability of monsoon has been presented. The role of internal variability in limiting the seasonal predictability is brought out and a mechanism of generation of the internal variability by the monsoon intraseasonal oscillations is identified. A novel real-time prediction strategy for forecasting intraseasonal variability 15-20 days in advance is developed. An important part of the thesis was done at LMD during my visits in 2003 and 2004, under the framework of Indo-France Centre for Environment and Climate (IFCEC) and supported by the French Government Scholarship for Advanced Scientific Research.

I did my M.Sc.(Engg. by research) in July 2002. During the period of my Masters, our efforts were to identify how the large scale intraseasonal oscillations modify the synoptic activity-genesis of low pressure systems-during the monsoon season. We have also developed an empirical model for the extended range (15-20 days) prediction of dry and wet spells of the Indian summer monsoon. For the first time we made a quantitative estimate of the limit of predictability of monsoon intraseasonal oscillations.

I have worked as Junior Research Fellow in an ISRO funded research project withProf. K Mohankumar, Department of Atmospheric Sciences, Cochin University of Science and Technology from January 1999 to July 2000. I also had the opportunity to work with Prof. P V Joseph, (Former Director, India Meteorological Department) UGC Visiting Professor, Department of Atmospheric Sciences, CUSAT.
