Evaluation of 3D‐Var and 4D‐Var data assimilation on simulation of heavy rainfall events over the Indian region

Abstract The present study delineates the relative performance of 3D‐Var and 4D‐Var data assimilation (DA) techniques in the regional NCUM‐R model to simulate three heavy rainfall events (HREs) over the Indian region. Four numerical experiments for three extreme rainfall cases were conducted by assi...
