Surface-atmosphere decoupling prolongs stratocumulus persistence under warm advection
29 May 2023
Li, Zhanqing
Supported by:
Research area: Cloud Processes
Enhancing the understanding of stratocumulus (Sc) cloud responses to meteorological factors could help reduce uncertainties in climate projections. Among various factors (lower-tropospheric stability, subsidence rate, wind speeds, etc.), the influence of horizontal temperature advection (Tadv), particularly warm-air advection (WADV), on Sc remains the least understood. This study elucidates the physical [...]
Importance of representing the haze particles in convection cloud chamber simulations
26 May 2023
Yang, Fan; Vogelmann, Andrew M.
Supported by:
Research area: Cloud-Aerosol-Precipitation Interactions
Cloud droplets develop from aerosol particles. But before an aerosol particle activates to a cloud droplet, it exists as a solution droplet, commonly referred to as haze. Most atmospheric models do not fully represent haze particles and the associated interactions with cloud droplets. By developing new microphysical models to explicitly [...]
Predicting airflow above canopies in complex terrain
25 May 2023
Chamecki, Marcelo
Supported by:
Research area: General Circulation and Single Column Models/Parameterizations
Mathematically describing air flow in the vicinity of tall canopies is required in a plethora of climate- and atmospheric-related applications. The swirling motion associated with air flow and how it interacts with the canopy structure has resisted complete theoretical treatment, which is the subject of this work.
Tracking the life cycle of thunderstorms: Perspectives from GoAmazon2014/15
23 May 2023
Giangrande, Scott
Supported by:
Research area: Vertical Velocity
The Amazon Basin has been at the forefront of impactful deep convective cloud (DCC) studies. Our study investigates daytime DCC observations to document changes in storm characteristics within the context of the larger-scale environmental shifts found between the Amazon wet and dry seasons. The focus is on the use of [...]
Evaluation of simulated cloud phase in EAMv2 at high latitudes
20 May 2023
Liu, Xiaohong
Supported by:
Research area: General Circulation and Single Column Models/Parameterizations
Mixed-phase clouds, in which liquid droplets and ice particles coexist at temperatures between 0 C and −40 C, play an essential role in modulating the surface energy budget and impacting future climate change. In this study, researchers used a satellite simulator to consistently evaluate model-simulated high-latitude clouds in the first [...]
