Dr Rajesh KUMAR

Dr Rajesh Kumar’s research work at CCRS focuses on atmosphere-ocean-wave interactions and modelling. He is currently focusing on the development of a high resolution regional coupled atmosphere-ocean-wave model (cSINGV) for Singapore region. He is also responsible for the operational ocean/wave forecasting system for MSS.
