My Career—Accomplishments, Experiences, and Work‐Life Balance
Perspectives of Earth and Space Scientists, Volume 4, Issue 1, December 2023., 2023 Abstract In describing my career, I have tried to share the experiences as well as the resume‐worthy accomplishments, trying to reflect not only the difficulties encountered but also the help from people along the way. After beginning with a short biography (initial conditions, education and training, career in a nutshell), I highlight some of the ...

Journal of Advances in Modeling Earth Systems, Volume 15, Issue 11, November 2023., 2023 Abstract Cumulus parameterization (CP) in state‐of‐the‐art global climate models is based on the quasi‐equilibrium assumption (QEA), which views convection as the action of an ensemble of cumulus clouds, in a state of equilibrium with respect to a slowly varying atmospheric state.

Geophysical Research Letters, Volume 50, Issue 20, 28 October 2023., 2023 Abstract This study reexamines cloud and precipitation variability associated with the Madden‐Julian Oscillation (MJO) over the Maritime Continent (MC), mainly using data acquired in 1998–2013 by the Tropical Rainfall Measuring Mission satellite. Infrared data indicated uniform, moderately deep stratiform cloud cover over the MC during MJO active ...

Is the Madden‐Julian Oscillation a Moisture Mode?
Geophysical Research Letters, Volume 50, Issue 15, 16 August 2023., 2023 Abstract The governing thermodynamics of the Madden‐Julian Oscillation (MJO) is examined using sounding and reanalysis data. On the basis of four objective criteria, results suggest that the MJO behaves like a moisture mode–a system whose thermodynamics is governed by moisture–only over the Indian Ocean. Over this basin, the MJO shows a slow convective

Langmuir Turbulence Controls on Observed Diurnal Warm Layer Depths
Geophysical Research Letters, Volume 50, Issue 10, 28 May 2023., 2023 Abstract The turbulent ocean surface boundary layer (OSBL) shoals during daytime solar surface heating, developing a diurnal warm layer (DWL). The DWL significantly influences OSBL dynamics by trapping momentum and heat in a shallow near‐surface layer. Therefore, DWL depth is critical for understanding OSBL transport and ocean‐atmosphere coupling.

The Diurnal Cycle of East Pacific Convection, Moisture, and CYGNSS Wind Speed and Fluxes
Journal of Geophysical Research: Atmospheres, Volume 128, Issue 8, 27 April 2023., 2023 Abstract The far eastern tropical Pacific is one of the rainiest locations on Earth. This region is characterized by a robust diurnal cycle with precipitation initiating over the Andes mountains in Colombia in the late afternoon and moving offshore overnight while organizing into mesoscale convective systems (MCSs).

Geophysical Research Letters, Volume 49, Issue 24, 28 December 2022., 2022 Abstract The sensitivity of coarse‐grained daily extreme precipitation to sea surface temperature is analyzed using satellite precipitation estimates over the 300–302.5 K range. A theoretical scaling is proposed, linking changes in coarse‐grained precipitation to changes in fine‐scale hourly precipitation area fraction and changes in conditional fine ...

AGU Advances, Volume 3, Issue 6, December 2022., 2022 Abstract Mesoscale convective systems (MCS) contribute about half of the world's precipitation and create flash flooding as well as other extreme weather events. Despite steady progress in research of these systems in the last several decades, better theoretical understanding is still needed to understand their dynamical organizations and to improve ...

Convective Momentum Transport and Its Impact on the Madden‐Julian Oscillation in E3SM‐MMF
Journal of Advances in Modeling Earth Systems, Volume 14, Issue 11, November 2022., 2022 Abstract Convective momentum transport (CMT) is the process of vertical redistribution of horizontal momentum by small‐scale turbulent flows from moist convection. Traditional general circulation models (GCMs) and their multiscale modeling framework (MMF) versions poorly represent CMT due to insufficient information of subgrid‐scale flows at each GCM ...

Journal of Geophysical Research: Atmospheres, Volume 127, Issue 19, 16 October 2022., 2022 Abstract Latent heating (LH) profiles from the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement mission (GPM) were employed to examine the LH distribution during the quasi‐biennial oscillation (QBO) disruption in the 2015/2016 Northern Hemispheric (NH) winter.
