Winter Term 2026

POA seminars will be held on Tuesdays at 3:30 PM in Burt 193.

Information will be updated as it becomes available.

If you would like to present, are hosting a visitor, know someone who might be interested, or have speaker suggestions, please contact Inés Leyba and Jasen Jacobsen, who are organizing this term's POA seminars. Also welcome are suggestions for non-OSU visiting speakers. POA discipline seminar funds are available to provide partial travel support for external visitors if needed.

  • January 27 – Inés Leyba, Calibration of a Wind–Drift Model and Boundary-Layer Wind Variability along the California Coast
    Abstract: Two studies motivated by observations from the Sub‑Mesoscale Ocean Dynamics Experiment (S-MODE) are presented in this seminar. S-MODE is a multi-instrument, multi-platform field campaign designed to investigate submesoscale ocean dynamics and their role in air–sea interaction and vertical transport offshore of the California Coast. 
    The first study tests and calibrates a recently proposed model for the near-surface wind and wave drift current in a homogeneous, equilibrium sea using a unique combination of remote-sensing and in situ velocity observations collected during the three S-MODE field campaigns. Five wind-drift model parameterizations are evaluated against multi-platform measurements of near-surface currents and vertical shear. The adjusted parameterizations substantially reduce bias in both drift magnitude and direction, bringing modeled vertical shear and shallow-layer drift into closer agreement with observations.
         The second study focuses on coastal low-level jets observed during the second intensive operations period of S-MODE, using radiosonde measurements along the California coast. These observations show frequent jet occurrences, with jet cores typically located near the top of the marine atmospheric boundary layer. Clustering of the observed jets by core height and intensity helps organize case‑to‑case variability and reveals consistent differences in vertical structure and temporal evolution across events.
