The Impact of Parameterized Convection on the Simulation of Crop Processes [PDF]

Journal of Applied Meteorology and Climatology, 2015
AbstractGlobal climate and weather models are a key tool for the prediction of future crop productivity, but they all rely on parameterizations of atmospheric convection, which often produce significant biases in rainfall characteristics over the tropics. The authors evaluate the impact of these biases by driving the General Large Area Model for annual

Global Simulation of the Madden–Julian Oscillation With Stochastic Unified Convection Scheme

Journal of Advances in Modeling Earth Systems, 2023
A new spectral convection scheme, the stochastic unified convection scheme (stochastic UNICON), is implemented in a general circulation model. The global climate simulation using stochastic UNICON is evaluated and compared with UNICON, focusing on the ...

Basic convective element: bubble or plume? A historical review [PDF]

Atmospheric Chemistry and Physics, 2014
During the 1950s and 1960s, when intensive investigations on atmospheric moist convection were launched, two possibilities were identified for the basic element of moist convection: bubble and plume.

Dependence of Convective Cloud Properties and Their Transport on Cloud Fraction and GCM Resolution Diagnosed from a Cloud-Resolving Model Simulation

Journal of Marine Science and Engineering, 2022
The scale-aware convective parameterization for high resolution global climate models must satisfy the requirement that the parameterized subgrid convective transport diminishes as the model resolution increases to convection-resolving resolutions.

Interhemispheric transport and the role of convective parameterizations [PDF]

Journal of Geophysical Research: Atmospheres, 1998
An F11 tracer simulation is performed here using the most recent Community Climate Model, the CCM3, of the National Center for Atmospheric Research (NCAR). Another F11 simulation performed with NCAR's CCM2 [Hartley et al, 1994] is also presented. Comparing the F11 mixing ratio in the models to Atmospheric Lifetime Experiment/Global Atmospheric Gases ...

Multi‐Grid Nesting Ability to Represent Convections Across the Gray Zone

Journal of Advances in Modeling Earth Systems, 2019
This study investigated the multi‐grid nesting ability of a limited area model to effectively represent convections across the gray zone, the resolution around 1–10 km where both cumulus parameterization and explicit convection are problematic.

Improving precipitation simulations in CIESM through a new entrainment rate parameterization

npj Climate and Atmospheric Science
Entrainment rate parameterization is important for convection schemes but uncertain in climate models. A new deep convective entrainment rate (λ) parameterization (HL parameterization) is developed from aircraft observations and implemented into the ...

Variability of Tropical Cyclone Frequency Over the Western North Pacific in 2018–2020

Frontiers in Climate, 2021
In this study, we examine the tropical cyclone (TC) activity over the western North Pacific (WNP) in 2018–2020 and its relationship with planetary scale convection and circulation anomalies, which play an important role for TC genesis.

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection

Advanced Materials Technologies, EarlyView.
A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

Effects of the Representation of Convection on the Modelling of Hurricane Tomas (2010)

Advances in Meteorology, 2017
The cumulus parameterization is widely recognised as a crucial factor in tropical meteorology: this paper intends to shed further light on the effects of convection parameterization on tropical cyclones’ numerical predictions in the “grey zone” (10–1 km ...
