Ongoing Research @WCMG
We focus to better understand the regional/local weather and climate phenomena, their variability and changes, through dynamical downscaling and analysis of observations. The members of the group also focus on improving the seasonal climate forecasts, cloud-resolving modelling of mesoscale convective systems, future projections of extremes at the regional and local scale in the Weather Research and Forecasting (WRF) model.
Understanding the Weather and Climate Extremes
Extreme rainfall events have severe consequences such as flash floods, landslides, crop damage, infrastructural damage, loss of human and animal lives, displacement of humans and animals etc. Their proper assessment of likely future trends are critical for setting up resilient infrastructure for disaster preparedness. We are analyzing extreme rainfall events happening during Indian Summer Monsoon over Northwest and Central India using high resolution reanalysis data.

Indian Winter Monsoon: Variability, Drivers, Trends and Simulation/Prediction
Winter precipitation is observed in the northern parts of Indian subcontinent through December to March due to the passage of western disturbances embedded in the sub-tropical westerly jet stream. This precipitation is a primary irrigational source for agriculture and plays a critical role in replenishing the water resources in the northern plains and maintaining the snow cover of the Himalayan glaciers. Being thickly populated, North India is prone to heavy destruction due to the increased frequency and intensity of extreme precipitation events such as, flash floods, cloudbursts, landslides, avalanches, etc. We aim to understand and simulate the winter precipitation dynamics and its key mechanisms over the Himalayas at a range of resolutions, including cloud-resolving scales.
Himalayan Rainfall Variability, Trends, Simulation and Predictability
The Himalayas, also known as the Water Tower, are a high mountain terrain with a complex interaction between atmosphere and topography. The complexity of the terrain and the high meteorological diversity make this region the most attractive to the research communities. Due to warming world, the changes in atmospheric conditions over the Himalayas cause in extreme precipitation events, flash floods, cloud bursts, river flooding, and landslides. We aim to understand and predict the summer monsoon rainfall and extreme rainfall events over the Himalayan mountains and downstream regions.
Investigation of Aerosol Variability and Dust storms
The atmospheric aerosols demonstrate spatial and temporal heterogeneity across the different part of India due to variable climatic conditions, intense urbanization and industrialization in the past decades. The abundances in aerosols concentrations can cause severe impacts on various sectors such as the ecosystem, atmospheric visibility, human health. Using state-of-the-art atmospheric modellig, available in-situ and remote sensing observations and global reanalyses, we aim to understand the physical process responsible for DSs and their influence on regional dynamics. We further develop the regional early warning system using numerical models to mitigate their impacts.
Heat Stress and its impacts
Global warming is not just a prediction anymore, we all know the earth is getting hotter day by day. Our body uses different metabolic mechanisms to maintain the core temperature, but when the temperature is above a certain level, body is not able to maintain the core temperature and heat stress occurs. Heat stress has many detrimental impacts on our body such as heat cramps, heat strokes etc. So, it makes the study over heat stress very vital so as to predict its intensity in the coming future. It would also help us to identify the hotspot region and form mitigation policies to tackle this threat.
