Baroclinic wave dynamics in the Ekman-free rotating rectangular annulus with localized forced plume
Shivam Swarnakar, Ayan Kumar Banerjee, Sridhar Balasubramanian +1
We report numerical simulations of a rotating rectangular annulus that isolates the Ekman-free bulk of the cylindrical baroclinic annulus, subjected to bi-directional temperature g…

Scalar mixing in non-Markovian homogeneous isotropic synthetic turbulence
Pratyush S. Awasthi, Joaquim P. Jossy, Amitabh Bhattacharya +1
We show that non-Markovianity of the velocity field is an essential property of turbulent mixing. We demonstrate this via passive scalar mixing by synthetically generated stochasti…

Machine Learning-Based Estimation of Superdroplet Growth Rates Using DNS Data
Divyaprakash, Nikita N. Makwana, Amitabh Bhattacharya +1
Droplet growth and size spectra play a crucial role in the microphysics of atmospheric clouds. However, it is challenging to represent droplet growth rate accurately in cloud-resol…
