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 ...

Evaluation of Modeled Diurnal Warming Estimates for Application to Producing Sea Surface Temperature Analyses

Earth and Space Science, Volume 11, Issue 9, September 2024.
Abstract Accurate knowledge of the amount of diurnal warming present in sea surface temperature (SST) observations at different times and effective depths is important for multiple applications including the production of blended SST analyses. This work explores the ability of a modified Kantha‐Clayson‐type one‐dimensional mixed layer ocean model with ...

Convection in TOGA COARE: Horizontal Scale, Morphology, and Rainfall Production [PDF]

Journal of the Atmospheric Sciences, 1998
Abstract The occurrence frequency and rainfall production of mesoscale convective systems (MCSs) relative to smaller groups of convective clouds over the tropical oceans is not well known. Eighty days of shipboard radar data collected during the recent Tropical Ocean Global Atmosphere Coupled Ocean–Atmosphere Response Experiment (TOGA COARE) were used ...

Near‐Storm Environmental Relationships With Tropical Oceanic Convective Structure Observed During NASA CPEX and CPEX‐AW

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 12, 28 June 2024.
Abstract Deep tropical oceanic convection (TOC) is a prevailing component of the tropical atmosphere and plays a significant role in modulating global weather and climate. Despite its importance, prediction challenges remain, partly attributed to a lack of understanding of how TOC relates to its near‐storm environments.

Horizontal Structure of the Upper Ocean Velocity and Density Fields in the Western Equatorial Pacific Warm Pool: Depth Range from 20 to 250 m [PDF]

, 2000
Wavenumber spectra of velocity and density fields in the western equatorial Pacific warm pool on scales 6–120 km are estimated using the shipboard survey data collected during the TOGA Coupled Ocean–Atmosphere Response Experiment (COARE). The spectra are

Rains and Showers in OTREC; Weak Temperature Gradient Modeling

Journal of Advances in Modeling Earth Systems, Volume 16, Issue 3, March 2024.
Abstract Rainfall in the tropics has been shown to be produced either by isolated but intense convective systems (showers regime) or widespread but weaker systems (rains regime). We examine significant rainfall systems observed in the OTREC project (Organization of Tropical East Pacific Convection) in order to tease out the physical mechanisms ...

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 ...
