Convection and Convective‐Organization in Hothouse Climates
Journal of Advances in Modeling Earth Systems, 2023 AbstractIn a “hothouse” climate, warm temperatures lead to a high tropospheric water vapor concentration. Sufficiently high water vapor levels lead to the closing of the water vapor infrared window, which prevents radiative cooling of the lower troposphere.

Theories of convection and the spectrum of turbulence in the solar photosphere [PDF]
, 2006 Classical theories of turbulence do not describe accurately inertial range scaling laws in turbulent convection and notably fail to model the shape of the turbulent spectrum of solar photospheric convection.

Multiple‐Instance Superparameterization: 1. Concept, and Predictability of Precipitation
Journal of Advances in Modeling Earth Systems, 2019 We have investigated the predictability of precipitation using a new configuration of the superparameterized Community Atmosphere Model (SP‐CAM). The new configuration, called the multiple‐instance SP‐CAM, or MP‐CAM, uses the average heating and drying ...

Journal of Advances in Modeling Earth Systems, 2019 The cloud‐permitting model (CPM) of the superparameterized Community Atmosphere Model (SP‐CAM) is a stochastic parameterization. As reported in a companion paper, we have created a variant of SP‐CAM, called MP‐CAM, that uses the averaged feedback of 10 ...

Granular Convection in Microgravity [PDF]
Physical Review Letters, 2013 We investigate the role of gravity on convection in a dense granular shear flow. Using a microgravity modified Taylor-Couette shear cell under the conditions of parabolic flight microgravity, we demonstrate experimentally that secondary, convective-like flows in a sheared granular material are close to zero in microgravity and enhanced under high ...

Tongan Volcanic Eruption Intensifies Tropical Cyclone Cody (2022)
Frontiers in Earth Science, 2022 The aerosol−cloud impacts of the Tongan volcanic eruptions on the nearby tropical cyclone (TC) Cody on January 14∼15, 2022 are investigated by the MODIS satellite and ERA5 reanalysis data.

Formation of Large-Scale Semi-Organized Structures in Turbulent Convection [PDF]
Phys.Rev. E66 (2002) 066305, 2002 A new mean-field theory of turbulent convection is developed. This theory predicts the convective wind instability in a shear-free turbulent convection which causes formation of large-scale semi-organized fluid motions in the form of cells or rolls. Spatial characteristics of these motions, such as the minimum size of the growing perturbations and the ...
