Disentangling regional drivers of top Antarctic snowfall days with a convolutional neural network

We leverage machine learning along side traditional synoptic diagnostic tools to identify the most important atmospheric drivers of Antarctic precipitation events. We find that in East Antarctica, the dynamic environment distinguished top precipitation events.

Synoptic and planetary-scale dynamics modulate antarctic atmospheric river precipitation intensity

In an investigation of circumpolar Antarctic atmospheric rivers we find that dynamical drivers, including Rossby waves excited by tropical convection, are a distinguishing feature of the highest precipitation events.

Synoptic drivers of atmospheric river induced precipitation near Dronning Maud Land, Antarctica

Using a self-organizing map and QG Omega analysis, we find that atmospheric rivers making landfall during the mature phase of cyclogenesis result in high-precipitation due to the spatial overlap of lift induced by frontogensis and the occlusion process.
