  • A low-level circulation in the tropics 

    Folkins, Ian, S. Fueglistaler, G. Lesins, and T. Mitovski. 2008. "A low-level circulation in the tropics." Journal of the Atmospheric Sciences 65(3): 1019-1034.
    Deep convective tropical systems are strongly convergent in the midtroposphere. Horizontal wind measurements from a variety of rawinsonde arrays in the equatorial Pacific and Caribbean are used to calculate the mean dynamical ...

  • Origin of lapse rate changes in the upper tropical troposphere 

    Folkins, Ian. 2002. "Origin of lapse rate changes in the upper tropical troposphere." Journal of the Atmospheric Sciences 59(5): 992-1005.
    Vertical motions in clouds arise from a variety of thermodynamic processes, including latent heat release, evaporative cooling, melting, and cloud radiative heating. In the Tropics, the net upward vertical mass flux from ...

  • Tropospheric aerosol optical thickness from the GOCART model and comparisons with satellite and sun photometer measurements 

    Chin, Mian, Paul Ginoux, Stefan Kinne, Omar Torres, et al. 2002. "Tropospheric aerosol optical thickness from the GOCART model and comparisons with satellite and sun photometer measurements." Journal of the Atmospheric Sciences 59(3): 461-483. doi:10.1175/1520-0469(2002)059<0461:TAOTFT>2.0.CO;2
    The Georgia Institute of Technology-Goddard Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) model is used to simulate the aerosol optical thickness t for major types of tropospheric aerosols including ...

  • The vertical structure of tropical convection and its impact on the budgets of water vapor and ozone 

    Folkins, Ian, and Randall V. Martin. 2005. "The vertical structure of tropical convection and its impact on the budgets of water vapor and ozone." Journal of the Atmospheric Sciences 62(5): 1560-1573. doi:10.1175/JAS3407.1
    Convective clouds in the Tropics that penetrate the boundary layer inversion preferentially detrain into a shallow outflow layer (2-5 km) or a deep outflow layer (10-17 km). The properties of these layers are diagnosed ...
