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 ...

An Observational Study of Entrainment Rate in Deep Convection
Atmosphere, 2015 This study estimates entrainment rate and investigates its relationships with cloud properties in 156 deep convective clouds based on in-situ aircraft observations during the TOGA-COARE (Tropical Ocean Global Atmosphere Coupled Ocean Atmosphere Response ...

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 ...

Modelling tracer transport by a cumulus ensemble: lateral boundary conditions and large-scale ascent [PDF]
Atmospheric Chemistry and Physics, 2004 The vertical transport of tracers by a cumulus ensemble at the TOGA-COARE site is modelled during a 7 day episode using 2-D and 3-D cloud-resolving setups of the Weather Research and Forecast (WRF) model.

Buoyancy of Convective Clouds in TOGA COARE
Journal of the Atmospheric Sciences, 1998 Abstract The buoyancy of convective clouds in TOGA COARE was calculated from the NCAR Electra in situ measurements of temperature, humidity, liquid water content, and two-dimensional images of raindrops. Most of the measurements were made at 700 mb (10°C) although some were made at 850 (18°C) and 600 mb (2°C).

Extended EOF Analysis of Tropical Disturbances: TOGA COARE
Journal of the Atmospheric Sciences, 1997 Empirical orthogonal function (EOF) analyses are performed of time‐height series of zonal and meridional winds and of cumulonimbus heating and drying in the Tropics. The data are from a rawinsonde array in the western Pacific located between the equator and 108S during the intensive observation period of the Tropical Ocean Global Atmosphere Coupled ...

Numerical simulation of tropical cumulus congestus during TOGA COARE [PDF]
Journal of Advances in Modeling Earth Systems, 2013 Recent observational studies of tropical deep convection typically include some mention of cumulus congestus, a third mode of tropical convection, in addition to shallow trade cumulus and deep convection. This study analyzes congestus behavior in a multiday cloud‐resolving model simulation based on the Tropical Ocean‐Global Atmosphere Coupled Ocean ...
