AbstractThe variation of near-surface air temperature anomalies in Africa between 1979 and 2010 is investigated primarily using Microwave Sounding Unit (MSU) total lower-tropospheric temperature data from the Remote Sensing Systems (RSS) and the University of Alabama in Huntsville (UAH) datasets. Significant increasing temperature trends were found in each of the following regions examined: all of Africa, Northern Hemisphere Africa, Southern Hemisphere Africa, tropical Africa, and subtropical… 
Southern Africa winter temperature shifts and their link to the Southern Annular Mode
Abstract The main characteristics of spatial and temporal variability of the winter (June–August) observed surface air minimum temperature (SAMT) of southern Africa (Africa south of the equator) were
Temperature variability over Africa during the last 2000 years
A growing number of proxy, historical and instrumental data sets are now available from continental Africa through which past variations in temperature can be assessed. This paper, co-authored by
Twentieth-Century Climate Change over Africa: Seasonal Hydroclimate Trends and Sahara Desert Expansion
AbstractTwentieth-century trends in seasonal temperature and precipitation over the African continent are analyzed from observational datasets and historical climate simulations. Given the
Changes in temperature and precipitation extremes in Ethiopia, Kenya, and Tanzania
East Africa is one of the most vulnerable regions of Africa to extreme weather and climate events. Regional and local information on climate extremes is critical for monitoring and managing the
Recent changes in air temperature, heat waves occurrences, and atmospheric circulation in Northern Africa
This study documents the time evolution of air temperature and heat waves occurrences over Northern Africa for the period 1979–2011. A significant warming (1°–3°C), appearing by the mid‐1960s over
Trends and variability of temperature and evaporation over the African continent: Relationships with precipitation
This study analyzed changes in African long-term (1901–2015) Potential Evapo-Transpiration (PET), precipitation, minimum (Tmin) and maximum (Tmax) temperature. Correlation among precipitation, PET,
Climatic deviations across a transect of South Africa during El Niño and La Niña years
South Africa is a water-scarce country that is highly dependent on agriculture. This means that the local impacts of climate altering phenomenon, such as the El Nino-Southern Oscillation (ENSO), are
