TL;DR: A synopsis of the current understanding of the spatio-temporal complexity of this important climate mode and its influence on the Earth system is provided and a unifying framework that identifies the key factors for this complexity is proposed.

TL;DR: In this article, a novel design of ocean general circulation model (OGCM) experiments to investigate the ocean's response to surface buoyancy and momentum flux perturbations without atmosphere-ocean feedbacks (e.g., without surface restoring or bulk formulae), as part of the Flux-Anomaly-Forced Model Intercomparison Project (FAFMIP).
Journal ArticleDOI
Diagnosing ENSO and global warming tropical precipitation shifts using surface relative humidity and temperature.
TL;DR: In this paper, a simplified method for diagnosing tropical precipitation change is tested on present day El Nino-Southern Oscillation (ENSO) precipitation shifts, based on the weak temperature gradient approximation, assuming precipitation is associated with local surface relative humidity (RH) and air temperature relative to the tropical mean.
Journal ArticleDOI
How much should we believe correlations between Arctic cyclones and sea ice extent
TL;DR: In this article, a cyclone identification and tracking algorithm is run for output from 100-year coupled climate model simulations at two resolutions and for 30 years of reanalysis data, using two different tracking variables (mean sea-level pressure, MSLP; and 850hPa vorticity) for identification of the cyclones.
Journal ArticleDOI
The Impact of the Direct Radiative Effect of Increased CO2 on the West African Monsoon
Robin Chadwick,Matthew Collins,F. Hugo Lambert,Ruth Geen,Alexander Todd,Christopher M. Taylor +5 more
TL;DR: In this article , an atmosphere-only model is used to examine both the equilibrium response and the evolution of the change over the days following the instantaneous CO2 increase, showing that WAM precipitation increases due to a weakening of the shallow meridional circulation over North Africa, advecting less dry air into the convective column associated with the monsoon.
