A Deep Learning Parameterization of Gravity Wave Drag Coupled to an Atmospheric Global Climate Model - Aditi Sheshadri
Kavli Institute for Theoretical Physics via YouTube
Overview
Syllabus
Intro
Gravity waves are ubiquitous..
Big source of uncertainty in climate prediction
Data Wave
Proof of concept.. Idealized model test
Model architecture - WaveNet
WaveNet does pretty well!
Predicting the QBO
Learning' one year is sufficient
Stable for 100 y times when run online
Increased CO2-WaveNet generalizes
QBO period, amplitude decrease
Future directions
Project Loon
Loon provides unprecedented coverage
Localize and analyze packets of gravity waves in time
Horizontal winds dominant predictors
