Press release: Climate change information needed for East African decision-making: Hon James Acidri (Uganda Member of Parliament) and Bob Natifu (Uganda Deputy Commissioner for Climate Change) open the HyCRISTAL “Research into Policy” Conference in Kampala, Uganda, 21-22 May 2019.

John Marsham, Beth Mackay, Gabriela Lopez Gonzalez, Dave Rowell, Barbara Evans, David Macdonald, Ros Cornforth

“Climate Change is already affecting our society and all regions of Uganda,” said Mr. Bob Natifu (Uganda Deputy Commissioner for Climate Change). His keynote address left attendees at the final annual HyCRISTAL (Integrating Hydro-Climate Science into Policy Decisions for Climate-Resilient Infrastructure and Livelihoods…

Press release: Met Office leads ground-breaking research collaboration on modelling African climate, showing enhanced future changes in wet and dry extremes

Jean-Pierre Roux, Zablone Owiti, Beth Mackay, Elizabeth Kendon, Cath Senior, Dave Rowell, John Marsham, Rachel James, Wilfried Pokam

A 4-year investment into one of the most ambitious research collaborations to date that focuses on African climate has delivered far-reaching results to advance international climate science. The international collaboration, led by the Met Office, the UK’s national meteorological service, has developed the first…

Future changes and uncertainty in decision-relevant measures of East African climate

F. Jorge Bornemann, David P. Rowell, Barbara Evans, Dan J. Lapworth, Kamazima Lwiza, David M.J. Macdonald, John H. Marsham, Kindie Tesfaye, Matthew J. Ascott, and Celia Way

The need for the development of adaptation strategies for climate change in Africa is becoming critical. For example, infrastructure with a long lifespan now needs to be designed or adapted to account for a future climate that will be different…

Brief: Designing a process for assessing climate resilience in Tanzania’s Rufiji River basin

Declan Conway, Robel Geressu, Julien Harou, Japhet J. Kashaigili, Laetitia Pettinotti, and Christian Siderius

This brief introduces the concept of climate information and reasons for its use in major decisions about water, energy and agriculture, including new infrastructure investments. It outlines the innovative approach taken in the Rufiji River basin in Tanzania by the…

Brief: Projecting future water availability in Lake Malawi and the Shire River basin

Ajay G. Bhave, Lauren Bulcock, Suraje Dessai, Declan Conway, Graham Jewitt, Andy J. Dougill, Seshagiri Rao Kolusu and David Mkwambisi

Malawi is highly dependent on water from Lake Malawi and the Shire River basin (Figure 1). Over 90% of Malawi’s electricity depends on outflows from the lake into the Shire River which feed three existing hydropower plants – Tedzani, Nkula…

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 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)…

Projected changes in tropical cyclones over the South West Indian Ocean under different extents of global warming

Mavhungu Muthige, Johan Malherbe, Francois A. Engelbrecht, Stefan Grab, Asmerom Beraki, Robert Maisha, and J Van der Merwe

The Paris Agreement achieved in December 2015 established that the signatory countries should pursue to hold the increase in global average temperature to below 2 °C relative to the preindustrial period and to strive to limit the temperature increase to 1.5 °C…

Rainfall intensification in tropical semi-arid regions: the Sahelian case

Gérémy Panthou, Thierry Lebel, Theo Vischel, Guillaume Quantin, Youssouph Sane, Ousmane Ndiaye, Aïda Diongue-Niang, and Marianne Diopkane

An anticipated consequence of ongoing global warming is the intensification of the rainfall regimes meaning longer dry spells and heavier precipitation when it rains, with potentially high hydrological and socio-economic impacts. The semi-arid regions of the intertropical band, such as…
