Title: Gregarious convection and radiative feedbacks in idealized worlds

Abstract

Abstract What role does convection play in cloud feedbacks? What role does convective aggregation play in climate? A flurry of recent studies explores “self‐aggregation” of moist convection in diverse simulations using explicit convection and interactive radiation. The implications involve upper level dry areas acting as infrared windows—the climate system's “radiator fins.” A positive feedback maintains these: dry columns undergo radiative cooling which drives descent and further drying. If the resulting clumpiness of vapor and cloud fields depends systematically on global temperature, then convective organization could be a climate system feedback. How reconcilable and how relevant are these interesting but idealized studies?

Observational Evidence of State‐Dependent Positive and Negative Land Surface Feedback on Afternoon Deep Convection Over the Southern Great Plains

Journal Article Qiu, Shaoyue ; Williams, Ian N. - Geophysical Research Letters

Abstract The detection of soil moisture‐precipitation feedback is complicated by the dependence of feedback sign on atmospheric state and cloud types. We evaluated responses of convective clouds to changes in surface evaporative fraction (EF) from satellite and ground‐based measurements over the Southern Great Plains in summer months. Strong responses to EF were inferred only after accounting for tropospheric states supporting systematically positive or negative responses. State dependence (inferred from controlled model experiments) explains the weak response found in previous studies. The probability of transitions from shallow to deep cumulus, and subsequent precipitation onset, increases by 58% over drier surfaces inmore »« less

Idealized Simulations of the Tropical Climate and Variability in the Single Column Atmosphere Model (SCAM): Radiative-Convective Equilibrium

Journal Article Hu, I‐Kuan ; Mapes, Brian E. ; Tulich, Stefan N. ; ... - Journal of Advances in Modeling Earth Systems

To explore the interactions among column processes in the Community Atmosphere Model (CAM), the single-column version of CAM (SCAM) is integrated for 1000 days in radiative-convective equilibrium (RCE) with tropical values of boundary conditions, spanning a parameter or configuration space of model physics versions (v5 vs. v6), vertical resolution (standard and 60 levels), sea surface temperature (SST), and some interpretation-driven experiments. The simulated time-mean climate is reasonable, near observations and RCE of a cyclic cloud-resolving model. Updraft detrainment in the deep convection scheme produces distinctive grid-scale structures in humidity and cloud, which also interact with radiative transfer processes. These gridmore »« less

Evaluating soil moisture feedback on convective triggering: Roles of convective and land–model parameterizations

Journal Article Williams, Ian N. - Journal of Geophysical Research: Atmospheres

Abstract Feedbacks between soil moisture and convective precipitation are not well represented in current Earth system models, and can affect projections of drought and heavy‐precipitation extremes. To explore the atmospheric and land‐surface influences on the initiation (triggering) of daytime deep convection, single‐column model experiments were performed using the NCAR Community Earth System Model (CESM1.2), over the U.S. Southern Great Plains. The results indicate that the positive and negative feedback mechanisms found in earlier studies (using simplified boundary‐layer models) are robust to large‐scale forcing and interactions between boundary‐layer turbulence, cloud dynamics, and radiation. However, systematic responses of convective triggering to soilmore »« less

Acceleration of tropical cyclogenesis by self-aggregation feedbacks

Journal Article Muller, Caroline J. ; Romps, David M. - Proceedings of the National Academy of Sciences of the United States of America

Idealized simulations of tropical moist convection have revealed that clouds can spontaneously clump together in a process called self-aggregation. This results in a state where a moist cloudy region with intense deep convection is surrounded by extremely dry subsiding air devoid of deep convection. Because of the idealized settings of the simulations where it was discovered, the relevance of self-aggregation to the real world is still debated. Here in this study, we show that self-aggregation feedbacks play a leadingorder role in the spontaneous genesis of tropical cyclones in cloudresolving simulations. Those feedbacks accelerate the cyclogenesis process by a factor ofmore »« less

Structural changes and variability of the ITCZ induced by radiation–cloud–convection–circulation interactions: inferences from the Goddard Multi-scale Modeling Framework (GMMF) experiments

Journal Article Lau, William K. M. ; Kim, Kyu-Myong ; Chern, Jiun-Dar ; ... - Climate Dynamics

In this paper, we have investigated the impact of radiation–cloud–convection–circulation interaction (RC3I) on structural changes and variability of the Inter-tropical Convergence Zone (ITCZ) using the Goddard Multi-scale Modeling Framework, where cloud processes are super-parameterized, i.e., explicitly resolved with 2-D cloud resolving models embedded in each coarse grid of the host Goddard Earth Observing System-Version 5 global climate model. Experiments have been conducted under prescribed sea surface temperature conditions for 10 years (2007–2016), with and without cloud radiation feedback in the atmosphere, respectively. Diagnostic analyses separately for January and July show that RC3I leads to an enhanced and expanded Hadley Circulationmore »« less
