This study is aimed to assess the performance of Numerical Weather Predication (NWP) model Weather Research and Forecasting (WRF) in simulating the season long rainfall pattern over the North-West Himalayan (NWH) region. For this purpose, two experiments are designed with identical initial conditions but varying cumulus physics options viz.; Kain-F...

The present study uses multi-temporal Sentinel-1 SAR dataset for classification of Saharanpur area in the Indo-Gangetic plains with December, January and Febru-ary month datasets of VV and VV/VH polarization. Support Vector Machine (SVM), Random Forest (RF), Decision Tree (DT) and Artificial Neural Network (ANN) algorithms with six different band c...

The present study investigates the effect of topography on the rainfall pattern of the North West Himalayan (NWH) region. The Weather Research and Forecasting (WRF) model is employed for conducting four dedicated experiments with varying topography at regional scale, which are assessed with respect to the control experiment of no-change in topograp...

Land evapotranspiration has a notable impact on the continental precipitation of India during monsoons. Given the heterogeneous land use and climate, India hosts many transition zones, which are hotspots for land‐atmosphere interactions. This work aims to study the soil moisture‐precipitation feedbacks over India by quantifying recycled precipitati...

In the present study, trends in heat stress during summer and monsoon season months were assessed for two cities, Pune and Mumbai, for the period of 47 years from 1969 to2015 with the application of empirically derived Heat Index (HI) and rational heat balance based Physiological Equivalent Temperature (PET) index. A stepwise multiple regression an...

Present work elucidates the impact of 3DVAR data assimilation technique for the simulation of one of the heavy rainfall events reported over Kotdwara region in the North-West Himalayan (NWH) region on 4th August 2017. We have examined the impact of conventional and satellite-based radiance datasets on the simulated results with and without assimila...
