Check out the new paper on "offline-online learning" of parameterizations for climate/turbulence to address shortcomings of supervised learning led by NWRA scientist Hamid Pahlavan published in @theAGU Geophysical Research Letters: doi.org/10.1029/2023GL106324 #NWRA_papers
The a posteriori performance of the CNN (a) in big-data regime, (b) in small-data regime and (c) after on-line re-training the CNN initially trained in the small-data regime. The period (τ) and amplitude (σ) of the true QBO are 28 - 0.7 and 21 - 0.3 m/s, respectively. The probability density functions (PDFs) of F and u become more similar to the true QBO after online re-training the CNN initially trained in the small-data regime.
