Convective Momentum Transport and Its Impact on the Madden‐Julian Oscillation in E3SM‐MMF

Journal of Advances in Modeling Earth Systems, Volume 14, Issue 11, November 2022., 2022
Abstract Convective momentum transport (CMT) is the process of vertical redistribution of horizontal momentum by small‐scale turbulent flows from moist convection. Traditional general circulation models (GCMs) and their multiscale modeling framework (MMF) versions poorly represent CMT due to insufficient information of subgrid‐scale flows at each GCM ...

Differences in Satellite‐Based Latent Heating Profiles Between the 2015/2016 Disruption and Westerly Phase of the Quasi‐Biennial Oscillation

Journal of Geophysical Research: Atmospheres, Volume 127, Issue 19, 16 October 2022., 2022
Abstract Latent heating (LH) profiles from the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement mission (GPM) were employed to examine the LH distribution during the quasi‐biennial oscillation (QBO) disruption in the 2015/2016 Northern Hemispheric (NH) winter.

Environmental Variability during TOGA COARE

Journal of the Atmospheric Sciences, 2000
Abstract This study provides quantitative estimates of the thermodynamic and kinematic structures of the troposphere during various convective regimes observed during the Tropical Ocean Global Atmosphere Coupled Ocean–Atmosphere Response Experiment. The data source is the upper air soundings from six stations in the intensive flux array.

SST Sensitivities in Multiday TOGA COARE Cloud-Resolving Simulations [PDF]

Journal of the Atmospheric Sciences, 2001
A two-dimensional cloud-resolving model (CRM) was used to simulate the evolution of convection over the western Pacific between 19 and 26 December 1992, during the Tropical Ocean Global Atmosphere Coupled Ocean‐Atmosphere Response Experiment. A control simulation (CONTROL) was performed in which observed, time-evolving, spatially homogeneous SSTs were ...

Desenvolvimento de uma parametrização do efeito de rajadas associadas a sistemas convectivos nos fluxos de calor na superfície utilizando Modelagem de Ensemble de Nuvens

Revista Brasileira de Meteorologia, 2013
Sistemas convectivos precipitantes produzem rajadas a partir de suas correntes descendentes, quando estas atingem a superfície. Tais rajadas têm a capacidade de amplificar os fluxos superficiais de calor sensível e latente, com possíveis consequências ...

Multiscale Air–Sea Interactions during TOGA COARE

Monthly Weather Review, 1997
Abstract Two distinct intraseasonal oscillations (ISO) are found in the tropical ocean atmosphere in the western Pacific region during Tropical Ocean Global Atmosphere Coupled Ocean–Atmosphere Response Experiment (TOGA COARE). The ISO is characterized by cycles of dry–wet phases in the atmosphere due to the passage of Madden–Julian oscillations, and ...

Cloud‐resolving simulation of TOGA‐COARE using parameterized large‐scale dynamics [PDF]

Journal of Geophysical Research: Atmospheres, 2013
Variations in deep convective activity during the 4 month Tropical Ocean Global Atmosphere‐Coupled Ocean Atmosphere Response Experiment (TOGA‐COARE) field campaign are simulated using a cloud‐resolving model (CRM). Convection in the model is coupled to large‐scale vertical velocities that are parameterized using one of two different methods: the damped
