Cumulus parameterization controls simulated rainfall more than microphysics, but not at heavy thresholds: a 3 * 2 factorial WRF study over the Western Himalaya
Satyam Kumar, Akshay Sunil, Devesh Sheoran
Rainfall forecasts over the Western Himalaya remain poor, and the relative contributions of the cumulus and microphysics parameterizations to that error are not well constrained.
Boundary-layer scheme selection outweighs microphysics in WRF simulations of the August 2018 Kerala extreme rainfall event
Satyam Kumar, Akshay Sunil, Rashad PE
Because precipitation is regulated by intricate interactions between topography, cloud microphysics,cumulus convection, radiation, and boundary-layer processes, it is still difficu…
Performance Evaluation of the WeatherEx Forecasting System (WFS) for Extreme Monsoon Rainfall over Kerala
Rashad P E, Akshay Sunil
Extreme monsoon rainfall over Kerala presents a major operational forecasting challenge because of the interaction of Arabian Sea moisture transport, mesoscale convection, coastal…
Toward Trustworthy Short-Range Forecasts with AFNO: From Skill Metrics to Conservation Checks
Akshay Sunil, B. Deepthi, Muhammed Rashid
Data driven weather models now approach traditional numerical weather prediction (NWP) skill at short to medium lead times, but their dynamical consistency during autoregressive ro…
Assessing the potential of state-of-the-art machine learning and physics-informed machine learning in predicting sea surface temperature
Akshay Sunil, B Deepthi, Gaurav Ganjir +3
The growing adoption of machine learning (ML) in modelling atmospheric and oceanic processes offers a promising alternative to traditional numerical methods. It is essential to ben…
