About
My research focuses on the climate variability and predictability on different time scales, with a focus on inter-basin interactions and teleconnections from the tropical oceans to the extratropical regions. I have worked on different aspects of the climate modelling to understand the role of air-sea interactions in the climate predictions across different timescales (sub-seasonal to season to decadal). My recent research shows that inter-basin interactions is a useful framework to understand sub-seasonality of the El Southern-Oscillation (ENSO) teleconnections to the different regions including Europe, where ENSO establishes its pathways through the Indian ocean to the early winter European climate, which direct ENSO pathways exists in latter half of the winter. I noted the occurrence of the Indian Ocean dipole (IOD) and ENSO dominates the early winter predictability of the North Atlantic Oscillation in the early winter. This is important to improve the understanding of climate predictions over the European region.
My research identified the role of the Indian ocean as the bridge between the ENSO and the winter climate over the South Asian region, where westerly disturbances plays are dominant mechanism for the snow and rainfall in the region. I also established the ENSO teleconnections with the Arabian Peninsula seasonal rainfall, where rainfall mainly occurs during the wet season(November-April).
I am also interested in the idealised modelling. I use intermediate complexity models as a research tool for understanding climate modes and their role in the climate variability and predictability across different timescales.
I briefly worked in the ITHACA project. Since October 2023, I am involved in ASPECT project. The focus of the ASPECT is to explore the seasonal to decadal timescale forecast and merge them along with climate projections to establish a unified seamless climate information system for the sectoral decision-making. The focus is on European climate prediction information including that of extreme weather events. The innovative scientific methodologies will be adapted for skill assessment and their sources and use the information for the user-relevant adaptation decisions. The project maintains a strong link with the WCRP lighthouse activities for explaining and predicting earth system changes.
