A Graph Neural Network Framework for Characterizing Rainfall Variability Regimes across India
Pradyumnan Raghuveeran, Gaurav Chopra, Ajay Bankar +1
The Indian Summer Monsoon shows significant spatial variation. While prior work primarily focused on forecasting rainfall amounts, little attention has been given to how consistent…
Prediction and Predictability of the Wet-Season Rainfall over Southeast India
Harini S, Devabrat Sharma, Yogenraj Patil +4
The challenge in predicting sub-regional climate within the Indian monsoon region is exacerbated by its increasing variability in a warming world. While exploring the seasonal pred…
Resolving the Paradox of Changing El Niño-Monsoon Relation through Synchronization of Chaotic Oscillators
Devabrat Sharma, Sagar Sedani, Shruti Tandon +3
For over a century, the relationship between Indian summer monsoon rainfall and El Nino-Southern Oscillation has been the foundation of 'long-range' prediction of Indian monsoon. T…
Evaluation of High-Resolution Gridded Precipitation Datasets Against a Dense Rain Gauge Network During the Indian Summer Monsoon
Ajay Bankar, Praveenkumar Venkatesan, Rakesh V +2
Advancements in remote sensing have led to development of several satellite-derived precipitation products; however, their accuracy must be evaluated before use in scientific and o…
A network-theoretic approach for characterizing Mack-mode instability in high-speed boundary layers
Sai Prasad Mohanty, Nikhil Khobragade, Gaurav Chopra +3
Here we present a network theory-based approach to investigate the Mack-mode instability signature found in high-speed schlieren data from a Mach 6 laminar boundary layer flow over…
Climatic Phase Transitions Unravel the Onset and Withdrawal of Indian Monsoon
Yogenraj Patil, Gaurav Chopra, Shruti Tandon +2
The livelihood and food security of more than a billion people depend on the Indian monsoon (IM). Yet, a universal definition of the large-scale season and progress of IM is missin…
Cross-variable amplitude-frequency coupling during intermittency in a turbulent thermoacoustic system
Shruti Tandon, Aswin Balaji, Rohit Radhakrishnan +3
We investigate flame-acoustic interactions in a turbulent combustor during the state of intermittency before the onset of thermoacoustic instability using complex networks. Experim…
