About

This is Dr. Dhangar from Texas Tech University, currently working as a CIWRO Postdoctoral Scholar with the University of Oklahoma.
My research focuses on understanding boundary layer processes and land–atmosphere interactions to improve numerical weather prediction, particularly across dryland and urban environments.
Currently, I investigate land–atmosphere feedback processes (LAFP) over West Texas and the Texas Panhandle, where drylines and frontal passages strongly influence convection. I evaluate the High-Resolution Rapid Refresh (HRRR) model using high-resolution observations from the West Texas Mesonet. Applying the encroachment model as a diagnostic framework, I develop process-based, weather-specific metrics to assess front-relative changes in near-surface temperature, moisture, wind, soil moisture controls, and atmospheric boundary layer (ABL) structure, including boundary layer depth and wind shear. This weather-scale evaluation helps identify parameterization gaps, reduce equifinality, and achieve “right answers for right reasons” in forecast models.
Previously, I served as a Project Scientist at the Indian Institute of Tropical Meteorology, contributing to the Winter Fog Experiment (WiFEX). My Ph.D. research examined the thermodynamic structure of winter fog over Delhi using observations and weather models, advancing understanding of fog physics, visibility, and urban boundary layer processes.
During my time in the Agrometeorology Division of the India Meteorological Department, my work focused on drought monitoring across India using the Standardized Precipitation Evapotranspiration Index (SPEI), validating soil moisture derived from the water balance method against satellite observations, and assessing heat stress impacts on livestock using the Temperature Humidity Index (THI). These efforts supported operational drought assessment, soil moisture monitoring, and heat risk evaluation for the agricultural sector.
I have extensive experience in meteorological field measurements, satellite and reanalysis data analysis, and atmospheric modeling with WRF, including ensemble fog forecasting. My work has been published in 24 peer-reviewed journals, including Journal of Geophysical Research: Atmospheres and Bulletin of the American Meteorological Society, and presented at international conferences such as the American Meteorological Society and European Geosciences Union. I also serve on the editorial board of Discover Springer Nature and have reviewed multiple articles for reputed journals in the field.
