What will your mission BE?

This postdoctoral project focuses on developing novel AI-driven generative models to better understand and predict the ocean’s response and feedback to tropical cyclones (TCs) and high latitude storms. The goal is to leverage cutting-edge machine learning techniques to explore how the coupled ocean-atmosphere system, particularly the upper ocean’s response, and how it modulates the dynamics of TCs and high latitude storms.

What will your activities BE?

– Utilize nextGEMS high-resolution climate simulations as the primary data source for training advanced AI models.
– Develop and train neural field representations to create compact and continuous representations of TC states and their surrounding oceanic environment.
– Evaluate the transferability of the developed model to high latitude storms.
– Train probabilistic diffusion models in the learned latent space to generate realistic ensembles of TC and storms evolutions.
– Design and utilize an Observing System Simulation Experiment (OSSE) framework to test the AI models and explore optimal observing strategies.
– Assess the realism of nextGEMS simulations against curated ancillary real-world observational datasets (e.g., satellite data from MAXSS/CyclObs/SWOT, Argo floats).
– Investigate the transferability of models trained on simulations to real observations, contributing to the PPR data challenge.
– Publish research findings in peer-reviewed journals and present at international conferences.
