Revealing the hidden link of the Walker circulation on heavy rainfall patterns in the Eastern Pacific

Communications Earth & Environment
Understanding the relationship between tropical heavy rainfall and large-scale circulation provides valuable insights for improving the climate models. Here we use Gaussian Mixture Model to identify two distinct types of heavy rainfall over the tropical ...

Diurnal variability of tropical rainfall retrieved from combined GOES and TRMM satellite information [PDF]

, 2002
Recent progress in satellite remote-sensing techniques for precipitation estimation, along with more accurate tropical rainfall measurements from the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) and precipitation radar (PR ...

Internal Ocean‐Atmosphere Variability in Kilometer‐Scale Radiative‐Convective Equilibrium

Journal of Advances in Modeling Earth Systems
We describe internal, low‐frequency variability in a 21‐year simulation with a cloud‐resolving model. The model domain is the length of the equatorial Pacific and includes a slab ocean, which permits coherent cycles of sea surface temperature (SST ...

Diagnostics of the tropical tropopause layer from in-situ observations and CCM data [PDF]

, 2009
A suite of diagnostics is applied to in-situ aircraft measurements and one Chemistry-Climate Model (CCM) data to characterize the vertical structure of the Tropical Tropopause Layer (TTL).

Changes of tropical precipitation and convective structure under global warming projected by CMIP5 model simulations

Terrestrial, Atmospheric and Oceanic Sciences, 2018
Regional changes of precipitation intensity, convective structure and column water vapor (CWV) in the Tropics are examined using climate model simulation outputs archived in the Coupled Model Intercomparison Project, phase 5 (CMIP5) for the ...

Entrainment versus Dilution in Tropical Deep Convection

Journal of the Atmospheric Sciences, 2017
AbstractThe distinction between entrainment and dilution is investigated with cloud-resolving simulations of deep convection in a tropical environment. A method for estimating the rate of dilution by entrainment and detrainment is presented and calculated for a series of bubble simulations with a range of initial radii.

Transitions toward a Mid-heavy State of Tropical Convection

Journal of Geophysical Research: Atmospheres
Abstract This study analyzes the thermodynamic effects of atmospheric vertical motion recorded in satellite observations to investigate the processes behind the evolution of tropical convection. These processes, difficult to observe directly, are diagnosed from satellite retrievals of precipitation (

The Effect of Pseudo‐Global Warming on the Weather‐Climate System of Africa in a Convection‐Permitting Model

Geophysical Research Letters
The African easterly jet (AEJ) and the West African Monsoon (WAM) can largely modulate high‐impact weather over Africa and the tropical Atlantic. How these features will change with a warming climate is just starting to be addressed due to global climate

Quasi‐Biennial Oscillation Influence on Tropical Convection and El Niño Variability

Geophysical Research Letters
The Quasi‐Biennial Oscillation (QBO) of descending zonal winds is the leading mode of tropical stratospheric variability. Numerous studies have explored its connection with the troposphere, including its sensitivity to El Niño‐Southern Oscillation (ENSO).

Circulation Models Cannot Simulate Organized Tropical Convection

Eos, 2015
Challenges in predicting and simulating the Madden-Julian Oscillation indicate a lack of understanding of the atmospheric circulation pattern's fundamental physics.
