    de Abreu, Lucia; Abrantes, Fatima G.; Shackleton, Nicholas J.; Tzedakis, Polychronis C.; McManus, Jerry F.; Oppo, Delia W.; Hall, Michael A. (American Geophysical Union, 2005-08-30)
    Similar orbital geometry and greenhouse gas concentrations during marine isotope stage 11 (MIS 11) and the Holocene make stage 11 perhaps the best geological analogue period for the natural development of the present ...
  • An ocean coupling potential intensity index for tropical cyclones 

    Lin, I.-I.; Black, Peter G.; Price, James F.; Yang, C.-Y.; Chen, Shuyi S.; Lien, C.-C.; Harr, Patrick; Chi, N.-H.; Wu, C.-C.; D'Asaro, Eric A. (John Wiley & Sons, 2013-05-15)
    Timely and accurate forecasts of tropical cyclones (TCs, i.e., hurricanes and typhoons) are of great importance for risk mitigation. Although in the past two decades there has been steady improvement in track prediction, ...
  • Ocean eddy dynamics in a coupled ocean-atmosphere model 

    Berloff, Pavel S.; Dewar, William K.; Kravtsov, Sergey K.; McWilliams, James C. (American Meteorological Society, 2007-05)
    The role of mesoscale oceanic eddies is analyzed in a quasigeostrophic coupled ocean–atmosphere model operating at a large Reynolds number. The model dynamics are characterized by decadal variability that involves nonlinear ...
  • Ocean preconditioning of Cyclone Nargis in the Bay of Bengal : interaction between Rossby waves, surface fresh waters, and sea surface temperatures 

    Yu, Lisan; McPhaden, Michael J. (American Meteorological Society, 2011-09)
    An in-depth data analysis was conducted to understand the occurrence of a strong sea surface temperature (SST) front in the central Bay of Bengal before the formation of Cyclone Nargis in April 2008. Nargis changed its ...
  • Ocean response to a hurricane, part II : data tabulations and numerical modeling
