Mechanisms behind early winter rainfall variability in the southwestern Cape, South Africa

Precious T. Mahlalela and Ross C. Blamey

The southwest region of South Africa is the only part of southern Africa that predominantly receives its total annual rainfall during the austral winter months (April–September). In 2015–2017, this part of the country experienced extreme dry conditions which led to…

Climate change in the Congo Basin: processes related to wetting in the December–February dry season

Amy Creese, Richard Washington, and Richard Jones

The Congo Basin is one of three key areas of tropical convection and contains the planet’s second largest rainforest. Understanding how global warming might change its climate is crucial, particularly during the dry seasons, when rainfall amounts currently bring the…

The Story of Water in Windhoek: A Narrative Approach to Interpreting a Transdisciplinary Process

Dianne Scott, Kornelia N. Iipinge, John K. E. Mfune, Davison Muchadenyika, Olavi V. Makuti, and Gina Ziervogel

The aim of the paper is to present a story about the 2015 to early 2017 Windhoek drought in the context of climate change while using the narrative approach. The story that is presented here is derived from the engagement…

Process‐based model evaluation and projections over southern Africa from Coordinated Regional Climate Downscaling Experiment and Coupled Model Intercomparison Project Phase 5 models

Izidine Pinto, Chris Jack, and Bruce Hewitson

Decision‐scale relevant climate information on climate change is needed to inform policy and decision making but often involves high uncertainty. To enhance confidence in interpreting regional climate projections, it is important to understand the underlying physical processes driving the change.…

Climate process chains: Examples from southern Africa

Joseph Daron, Laura Burgin, Tamara Janes, Richard G. Jones, and Christopher Jack

The climate system comprises multiple components, primarily the atmosphere, ocean and cryosphere, each incorporating physical processes that interact across scales. To help understand the behaviour of this complex system, and evaluate climate model simulations, researchers typically take a reductionist approach,…

A Methodological Approach to Assess the Co-Behavior of Climate Processes over Southern Africa

Kwesi A. Quagraine, Bruce Hewitson, Christopher Jack, Izidine Pinto, and Christopher Lennard

The study develops an approach to assess co-behavior of climate processes. The regional response of precipitation and temperature patterns over southern Africa to the combined roles (co-behavior) of El Niño–Southern Oscillation (ENSO), Antarctic Oscillation (AAO), and intertropical convergence zone (ITCZ)…

Assessment of the Representation of West African Storm Lifecycles in Convection‐Permitting Simulations

Julia Crook, Cornelia Klein, Sonja Folwell, Christopher M. Taylor, Douglas J. Parker, Rachel Stratton, and Thorwald Stein

Convection‐permitting models perform better at representing the diurnal cycle and the intermittency of convective rainfall over land than parameterized‐convection models. However, most of the previous model assessments have been from an Eulerian point of view, while key impacts of the…

Trends in flood events and their relationship to extreme rainfall in an urban area of Sahelian West Africa: The case study of Ouagadougou, Burkina Faso

Fowe Tazen, Abdoulaye Diarra, Rodrigue F.W. Kabore, Boubacar Ibrahim, Maïmouna Bologo/Traoré, Karim Traoré, and Harouna Karambiri

Urban areas in Sahelian West Africa are highly vulnerable to extreme hydro‐meteorological events. In recent years, Burkina Faso has experienced several natural disasters with floods being the most frequent. This study investigates flood trends in Ouagadougou and their relationship to…

Less frequent and more intense rainfall along the coast of the Gulf of Guinea in West and Central Africa (1981–2014)

Adeline Bichet and Arona Diedhiou

Since the 1990s, rainfall has been reported to increase over the Gulf of Guinea. In light of the devastating floods that have occurred since the 1990s over the coastal areas of this region, this work aims to better characterize the…

Intensity–duration–frequency (IDF) rainfall curves in Senegal

Youssouph Sane, Geremy Panthou, Ansoumana Bodian, Theo Vischel, Thierry Lebel, Honore Dacosta, Guillaume Quantin, Catherine Wilcox, Ousmane Ndiaye, Aida Diongue-Niang, and Mariane Diop Kane

Urbanization resulting from sharply increasing demographic pressure and infrastructure development has made the populations of many tropical areas more vulnerable to extreme rainfall hazards. Characterizing extreme rainfall distribution in a coherent way in space and time is thus becoming an…
