Preconditioning Deep Convection with Cumulus Congestus [PDF]
Journal of the Atmospheric Sciences, 2013 Abstract Recent studies have pushed forward the idea that congestus clouds, through their moistening of the atmosphere, could promote deep convection. On the other hand, older studies have tended to relate convective initiation to the large-scale forcing. These two views are here contrasted by performing a time-scale analysis.

Global climate impacts of stochastic deep convection parameterization in the NCAR CAM5
Journal of Advances in Modeling Earth Systems, 2016 In this study, the stochastic deep convection parameterization of Plant and Craig (PC) is implemented in the Community Atmospheric Model version 5 (CAM5) to incorporate the stochastic processes of convection into the Zhang‐McFarlane (ZM) deterministic ...

North Atlantic deep water formation and AMOC in CMIP5 models [PDF]
Ocean Science, 2017 Deep water formation in climate models is indicative of their ability to simulate future ocean circulation, carbon and heat uptake, and sea level rise.

Journal of Advances in Modeling Earth Systems, 2023 We extend the previously developed stochastic unified convection scheme (UNICON) for shallow convection to deep convection by parameterizing the impact of mesoscale organized flow on updraft properties.

Deep convective clouds at the tropopause [PDF]
Atmospheric Chemistry and Physics, 2011 Abstract. Data from the Atmospheric Infrared Sounder (AIRS) on the EOS Aqua spacecraft each day show tens of thousands of Cold Clouds (CC) in the tropical oceans with 10 μm window channel brightness temperatures colder than 225 K. These clouds represent a mix of cold anvil clouds and Deep Convective Clouds (DCC).

Seasonal dynamics and annual budget of dissolved inorganic carbon in the northwestern Mediterranean deep-convection region [PDF]
Biogeosciences, 2023 Deep convection plays a key role in the circulation, thermodynamics, and biogeochemical cycles in the Mediterranean Sea, which is considered to be a hotspot of biodiversity and climate change.

Empirical evidence for deep convection being a major source of stratospheric ice clouds over North America [PDF]
Atmospheric Chemistry and Physics, 2021 Ice clouds in the lowermost stratosphere affect stratospheric water vapour and the Earth's radiation budget. The knowledge of its occurrence and driving forces is limited.

Simulating model uncertainty of subgrid-scale processes by sampling model errors at convective scales [PDF]
Nonlinear Processes in Geophysics, 2020 Ideally, perturbation schemes in ensemble forecasts should be based on the statistical properties of the model errors. Often, however, the statistical properties of these model errors are unknown. In practice, the perturbations are pragmatically modelled

Journal of Advances in Modeling Earth Systems, 2020 In order to improve the physical consistency between shallow and deep convection, we modify the deep convective closure in the Community Atmosphere Model version 5 (CAM5) coupled with a third‐order turbulence closure parameterization (i.e., Cloud Layers ...

Why did deep convection persist over four consecutive winters (2015–2018) southeast of Cape Farewell? [PDF]
Ocean Science, 2020 After more than a decade of shallow convection, deep convection returned to the Irminger Sea in 2008 and occurred several times since then to reach exceptional convection depths (> 1500 m) in 2015 and 2016.
