ResU‐Deep: Improving the Trigger Function of Deep Convection in Tropical Regions With Deep Learning
Journal of Advances in Modeling Earth Systems, 2023 Modeling deep convection accurately in tropical regions is important. However, biases remain in current trigger functions. To alleviate the overestimation of frequency and wrong depiction of the diurnal cycle, we propose a deep convection trigger ...

Increasing vertical mixing to reduce Southern Ocean deep convection in NEMO3.4 [PDF]
Geoscientific Model Development, 2015 Most CMIP5 (Coupled Model Intercomparison Project Phase 5) models unrealistically form Antarctic Bottom Water by open ocean deep convection in the Weddell and Ross seas.

Diabatic processes modulating the vertical structure of the jet stream above the cold front of an extratropical cyclone: sensitivity to deep convection schemes [PDF]
Weather and Climate Dynamics, 2022 The effect of deep convection parameterisation on the jet stream above the cold front of an explosive extratropical cyclone is investigated in the global numerical weather prediction model ARPEGE, operational at Météo-France.

Deep Convection Along the Continental Slope in the East/Japan Sea: A Large-Eddy Simulation Study
Frontiers in Marine Science, 2022 Sparse observations in the East/Japan Sea (EJS) suggested that open-ocean deep convection occurs south of Vladivostok; however, more recent observations suggest that deep convection occurs along the continental slope, resulting in bottom water formation ...

A Baseline for Global Weather and Climate Simulations at 1 km Resolution
Journal of Advances in Modeling Earth Systems, 2020 In an attempt to advance the understanding of the Earth's weather and climate by representing deep convection explicitly, we present a global, four‐month simulation (November 2018 to February 2019) with ECMWF's hydrostatic Integrated Forecasting System ...

Identifying the Deep‐Inflow Mixing Features in Orographically‐Locked Diurnal Convection
Geophysical Research Letters, 2023 Orographically‐locked diurnal convection involves interactions between local circulation and the thermodynamic environment of convection. Here, the relationships of convective updraft structures over orographic precipitation hotspots and their upstream ...

Parameterizing deep convection using the assumed probability density function method [PDF]
Geoscientific Model Development, 2015 Due to their coarse horizontal resolution, present-day climate models must parameterize deep convection. This paper presents single-column simulations of deep convection using a probability density function (PDF) parameterization.
