Research interests

    I was joined a staff of AOML's Physical Oceanography Division in August 2018 as a University of Miami-Cooperative Institute (CIMAS) post-doctoral scientist. I'm currently working a CPO-funded project that uses climate models to study the impact of the Atlantic meridional overturning circulation (AMOC) on global atmospheric circulations and subseasonal forecast in the U.S. tornado activity. Here are my research interests:

    • Modulation of the Atlantic Meridional Overturning Circulation(AMOC) and its impacts on climate variations using GCMs :

    - Impacts of the Atlantic Multidecadal Oscillation (AMO) on the El Niño activity and diversity
    - Change in pathway of AMOC and its impact on global atmospheric circulation

    • Physical mechanism of U.S. tornadogenesis in multi-timescales :

    - Underlying physical mechanism of relationship between MJO and U.S. tornadogenesis
    - Spatiotemooral variation of U.S. tornadogenesis in decadal timescales

    • Development of Earth System Model (ESM) with carbon and nitrogen cycle :

    - Development of the parameterization for terrestrial carbon cycle in ESMs
    - Impact of ocean-atmospheric interaction on the terresterial carbon & hydrological cycles

Research highights

    Underying physical mechanism of MJO-U.S. tornadogenesis: Previous studies have suggested a strong statistical relationship between MJO and U.S. tornado activity. However, physical mechanism of the MJO- U.S. tornadogenesis relationship has not been fully understood. We demostrated that MJO-induced reduction of atmospheric convective activity over the northeast tropical Pacific enhances the North American Low-Level Jet (NALLJ) in MJJ and thus increases the low-level wind shear and convective available potential energy (CAPE) over the U.S. These atmospheric conditions in MJJ are highly conducive to U.S. tornadogenesis. The identified link between northeast Pacific atmospheric convection and US tornadogenesis will be used to explore a subseasonal forecast model for U.S. tornadogenesis in MJJ (Kim et al., 2020).
