  1. A Cyclonic Eddy in Lee Side of Lanai Island, Hawaii C. Charles Dong IGPP, UCLA Collaborators: T. Mavor, M. Ondrusek (NOAA), S. Jiang, T Dickey, F. Nencioli (UCSB) Y. Uchiyama, H. Zhang, J. McWilliams (UCLA) M. Yarbrough, S. Flora (Moss Landing, CalState)

  2. On Dec. 18, 2007, MOBY broke free from its mooring, and about three days later it was recovered. Lanai http://physoce.mlml.calstate.edu/moby/moby239/index.html

  11. Summary: • MOBY broke from its mooring and followed a cyclonic eddy • during three days before its recovery. Satellite SST and Chl • data are applied to the analysis. • 2. Using hindcasting mode, ROMS can statistically reproduce • the eddy detected. • Next Step: • A high-resolution MM5/WRF product is applied to provide the • surface flux • Forecasting Pacific model (JPL) provides the BC to improve • the boundary flux.
