What the literature leaves open

  • Further investigation of the interplay between ENSO and NTA SST anomalies, - Exploration of other climate phenomena using deep learning models, - Development of more advanced deep learning architectures for climate prediction

  • The paper identifies a gap in the predictability of NTA SST anomalies and their predictive precursors. The study notes that prior work has evaluated the performance of dynamical seasonal forecast systems, but there is a need for a deep learning framework. The paper also identifies a gap in the evaluation of the teleconnection between the previous winter ENSO and the boreal spring NTA.
