Abstract The warming of the entire tropical free troposphere in response to El Nino is well established, and suggests a tropical mechanism for the El Nino–Southern Oscillation (ENSO) teleconnection. The potential impact of this warming on remote tropical climates is examined through investigating the adjustment of a single-column model to imposed tropospheric temperature variations, assuming that ENSO controls interannual tropospheric temperature variations at all tropical locations. The column…

Mechanisms of Remote Tropical Surface Warming during El Niño

Abstract The authors demonstrate through atmospheric general circulation model (the Community Climate Model version 3.10) simulations of the 1997/98 El Nino that the observed “remote” (i.e., outside

Adjustment of the Remote Tropical Climate to El Niño Conditions

Abstract The adjustment of the tropical climate outside the Pacific (the “remote Tropics”) to the abrupt onset of El Nino conditions is examined in a tropical atmosphere model that assumes simplified

Intensification of El Niño-induced atmospheric anomalies under greenhouse warming

The El Niño/Southern Oscillation (ENSO) has a profound influence on global climate and ecosystems. Determining how the ENSO responds to greenhouse warming is a crucial issue in climate science.

Revisiting ENSO Atmospheric Teleconnections and Challenges

The warming of the equatorial Pacific associated with the El Niño–Southern Oscillation (ENSO) causes profound impacts on rainfall and temperature in the tropics and extratropics. El Niño drives

Decadal changes of the wintertime tropical tropospheric temperature and their influences on the extratropical climate

A decadal change of the tropical tropospheric temperature (TT) was identified to occur in the winter of 1997. Compared with that in the former period (1979–1996), the wintertime TT was significantly

Sensitivity of South American Tropical Climate to Last Glacial Maximum Boundary Conditions: Focus on Teleconnections with Tropics and Extratropics

We explore how the moist deep convection over the Amazonian region responds to glacial forcings compared to the pre-indrustrial climate and how this change might interact with the meridional shift of

Mechanisms for Lagged Atmospheric Response to ENSO SST Forcing

The mechanism and sensitivity of the lagged response of tropical tropospheric temperature to El Nino– Southern Oscillation (ENSO) SST forcing are examined using the Quasi-Equilibrium Tropical

ENSO’s impacts on the tropical Indian and Atlantic Oceans via tropical atmospheric processes: observations versus CMIP5 simulations

This study compares the impacts of the El Niño–Southern Oscillation (ENSO) on sea surface temperatures (SSTs) in the tropical North Atlantic Ocean and the tropical Indian Ocean during 1958–2004. It
