Inland Deforestation Organizes Convective Extremes.

open access: yes
Abstract Large-scale deforestation is rampant in the Amazon region and has been shown to induce decreases in mean precipitation over deforested regions. Yet, the impact of deforestation on precipitation extremes remains largely unexplored.

Convective organization and 3D structure of tropical cloud systems deduced from synergistic A-Train observations and machine learning [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
We are building a 3D description of upper tropospheric (UT) cloud systems in order to study the relation between convection and cirrus anvils. For this purpose we used cloud data from the Atmospheric InfraRed Sounder and the Infrared Atmospheric Sounding

Impact of resolution on large-eddy simulation of midlatitude summertime convection [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
We analyze life cycles of summertime moist convection of a large-eddy simulation (LES) in a limited-area setup over Germany. The goal is to assess the ability of the model to represent convective organization in space and time in comparison to radar data

Radiative Convective Equilibrium and Organized Convection: An Observational Perspective [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2019
AbstractRadiative convective equilibrium (RCE) describes a balance between the cooling of the atmosphere by radiation and the heating through latent heat release and surface heat fluxes. While RCE is known to provide an energetic constraint on the atmosphere at the global scale, little is known about the proximity of the atmosphere to RCE at smaller ...

Entrainment and Its Dependency on Environmental Conditions and Convective Organization in Convection-Permitting Simulations [PDF]

open access: yesMonthly Weather Review, 2021
AbstractIn this study, we estimate bulk entrainment rates for deep convection in convection-permitting simulations, conducted over the tropical Atlantic Ocean, encompassing parts of Africa and South America. We find that, even though entrainment rates decrease with height in all regions, they are, when averaging between 600 and 800 hPa, generally ...

Convective Momentum Transport and Its Impact on the Madden‐Julian Oscillation in E3SM‐MMF

open access: yesJournal of Advances in Modeling Earth Systems, 2022
Convective momentum transport (CMT) is the process of vertical redistribution of horizontal momentum by small‐scale turbulent flows from moist convection.

Mesoscale simulations of organized convection: Importance of convective equilibrium [PDF]

open access: yesQuarterly Journal of the Royal Meteorological Society, 2006
AbstractThe validity of convective parametrization breaks down at the resolution of mesoscale models, and the success of parametrized versus explicit treatments of convection is likely to depend on the large‐scale environment. In this paper we examine the hypothesis that a key feature determining the sensitivity to the environment is whether the ...

Spatial Organisation Affects the Pathway to Precipitation in Simulated Trade‐Wind Convection

open access: yesGeophysical Research Letters, 2023
We investigate whether and how spatial organization affects the pathway to precipitation in large‐domain hectometer simulations of the North Atlantic trades.

Mesoscale Convective Systems Modulated by Convectively Coupled Equatorial Waves

open access: yesGeophysical Research Letters, 2023
Mesoscale convective systems (MCSs) produce over 50% of tropical precipitation and account for the majority of extreme rainfall and flooding events. MCSs are considered the building blocks of larger‐scale convectively coupled equatorial waves (CCEWs ...
