Oceanic Forcing of Sahel Rainfall on Interannual to Interdecadal Time Scales
We present evidence, based on an ensemble of integrations with NSIPP1 (version 1 of the atmospheric general circulation model developed at NASA's Goddard Space Flight Center in the framework of theExpand

Interannual Variability of Caribbean Rainfall, ENSO, and the Atlantic Ocean*
Abstract The large-scale ocean–atmosphere patterns that influence the interannual variability of Caribbean–Central American rainfall are examined. The atmospheric circulation over this region isExpand

Deconstructing Atlantic Intertropical Convergence Zone variability: Influence of the local cross‐equatorial sea surface temperature gradient and remote forcing from the eastern equatorial Pacific
(1) We investigate causes of interannual variability in Atlantic Intertropical Convergence Zone (ITCZ) convection using a monthly mean global precipitation data set spanning 1979-1999. Starting fromExpand

The ENSO Teleconnection to the Tropical Atlantic Ocean: Contributions of the Remote and Local SSTs to Rainfall Variability in the Tropical Americas*
Recent developments in Tropical Atlantic Variability (TAV) identify the El Nino-Southern Oscillation (ENSO) as one of the leading factors in the interannual climate variability of the basin. An ENSOExpand

A global perspective on African climate
We describe the global climate system context in which to interpret African environmental change to support planning and implementation of policymaking action at national, regional and continentalExpand

Interdecadal Changes in the ENSO Teleconnection to the Caribbean Region and the North Atlantic Oscillation
Abstract The El Nino–Southern Oscillation (ENSO) phenomenon and variability in the subtropical North Atlantic high sea level pressure (SLP) are known to affect rainfall in the Caribbean region. An ElExpand

The preconditioning role of Tropical Atlantic Variability in the development of the ENSO teleconnection: implications for the prediction of Nordeste rainfall
Abstract A comparison of rainfall variability in the semi-arid Brazilian Nordeste in observations and in two sets of model simulations leads to the conclusion that the evolving interaction betweenExpand

A climate model-based review of drought in the Sahel: Desertification, the re-greening and climate change
We review the evidence that connects drought and desertification in the Sahel with climate change past, present and future. Advances in climate modeling point to the oceans, not land, as the cause ofExpand

Dynamics of the boreal summer African monsoon in the NSIPP1 atmospheric model
A nine-member ensemble of simulations with a state-of-the-art atmospheric model forced only by the observed record of sea surface temperature (SST) over 1930–2000 is shown to capture the dominantExpand

Robust Sahel drying in response to late 20th century forcings
[1] The African Sahel experienced severe drying between the 1950s and the 1980s, with partial recovery since. We compare Sahel rainfall in the 20th century, pre-industrial, and increased greenhouseExpand
