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 the Seasonal-to-Interannual Prediction Project) forced only by the observed record of sea surface temperature from 1930 to 2000, to suggest that variability of rainfall in the Sahel results from the response of the African summer monsoon to oceanic forcing, amplified by land-atmosphere interaction. The… 

Oceanic forcing of the late 20th century Sahel drought

The Sahel region of Africa underwent a pronounced interdecadal drying trend in the latter half of the 20th century. In order to investigate this drying trend, several ensembles of numerical

Understanding Pacific Ocean influence on interannual precipitation variability in the Sahel

Moisture budget decomposition is performed for the Sahel (10°–20°N and 20°W–40°E) in order to understand the processes that govern regional hydroclimate variability on interannual time scales and

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 dominant

Observation of oceanic origin of Sahel precipitation from space


INTRODUCTION The drying trend in the semiarid Sahel was attributed to warmer-than-average low-latitude waters around Africa, which, by favouring the establishment of deep convection over the ocean,

Moisture budget analysis of SST-driven decadal Sahel precipitation variability in the twentieth century

It is well known that the Sahel region of Africa is impacted by decadal scale variability in precipitation, driven by global sea surface temperatures. This work demonstrates that the National Center

Ocean Warming and Late-Twentieth-Century Sahel Drought and Recovery

Abstract The influences of decadal Indian and Atlantic Ocean SST anomalies on late-twentieth-century Sahel precipitation variability are investigated. The results of this regional modeling study show

An Externally Forced Decadal Rainfall Seesaw Pattern Over the Sahel and Southeast Amazon

By analyzing observations and model simulations, here we show that there exists a significant anticorrelation on interannual to multidecadal time scales between the Sahel and southeast Amazon

The dynamics of the Indian Ocean sea surface temperature forcing of Sahel drought

Given the pronounced warming in the Indian Ocean sea surface temperature (SST) during the second half of the twentieth century and the empirical relationship between the Indian Ocean SST and Sahel

Robust Sahel drought due to the Interdecadal Pacific Oscillation in CMIP5 simulations

Many studies address the Interdecadal Pacific Oscillation (IPO) as a modulator of climate in several regions all over the globe. However, very few suggest that it has an impact on Sahel rainfall



Influence of the Atlantic, Pacific and Indian Oceans on Sahel rainfall

Folland et al.1 have reported that persistently dry and wet periods of several years in the Sahel have been accompanied by global-scale patterns of sea-surface temperature (SST) anomaly. They also

Sahel rainfall and worldwide sea temperatures, 1901–85

Using the comprehensively quality-controlled Meteorological Office Historical Sea Surface Temperature data set (MOHSST)1,2 we show for the first time that persistently wet and dry periods in the

Enhancement of Interdecadal Climate Variability in the Sahel by Vegetation Interaction.

The role of naturally varying vegetation in influencing the climate variability in the West African Sahel is explored in a coupled atmosphere-land-vegetation model and interactive vegetation enhances the interdecadal variation substantially but can reduce year-to-year variability.

Mechanisms by Which Gulf of Guinea and Eastern North Atlantic Sea Surface Temperature Anomalies Can Influence African Rainfall

Abstract The sensitivity of precipitation over West Africa to sea surface temperature anomalies (SSTAs) in the Gulf of Guinea and the eastern North Atlantic is studied using a GCM. Results from nine

Tropical tropospheric temperature variations caused by ENSO and their influence on the remote tropical climate

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.

Diagnosis and Short-Lead Time Prediction of Summer Rainfall in Tropical North Africa at Interannual and Multidecadal Timescales

Abstract The summer climate of tropical North Africa exhibits strong decadal variability (the low frequency, LF) and also substantial variability within the decadal regimes (the high frequency, HF).

West African Monsoon Dynamics and Eastern Equatorial Atlantic and Pacific SST Anomalies (1970-88)

Abstract The Laboratoire de Meteorologie Dynamique atmospheric GCM is used to investigate relationships between West African monsoon dynamics and SST anomalies in the eastern equatorial Atlantic and

Ocean‐atmosphere‐land feedbacks in an idealized monsoon

An intermediate‐complexity atmospheric model coupled with a simple land‐surface model and a mixed‐layer ocean model is used to investigate the processes involved in an idealized monsoon occurring on

Case Studies of Tropical Atlantic Surface Circulation Patterns During Recent Sub-Saharan Weather Anomalies: 1967 and 1968

Abstract Sub-Saharan West Africa (10–20°N) receives moisture from the tropical Atlantic via low-level south-westerly flow across the southwestern coast of West Africa. This paper utilizes a 1arge

Variability of summer rainfall over tropical north Africa (1906–92): Observations and modelling

The nature and causes of seasonal (July to September (JAS)) rainfall variability over tropical north Africa are investigated using a combination of empirical and modelling approaches. Concentration
