Professor A. P. Dimri has firmly established himself as the expert on the wintertime precipitation in the Indian winter monsoon context. He is a leading expert globally on topics such as winter extra-tropical cyclones and Western Disturbances, their manifestation and interplay with Himalayan topography. His work has developed the disciplinary knowledge of the dynamical and thermodynamical processes associated with winter events. Another unique contribution by Prof. Dimri to the field lies in the development of Cloudburst analysis for the Himalayan region – as a convective initiated trigger by orographic locking around the western and central Himalayas. Thus, providing an exact definition of it, which was elusive thus far. Further he continues to push the envelope of the accepted paradigms and help develop new understanding and proposed a novel method to study the temperature distribution over mountains in the form of Slope Environmental Lapse Rate modeling. essential to differentiate the atmospheric lapse rate for the monsoon glaciohydrological regime of Himalaya.
