We analyze the potential effect of global warming levels (GWLs) 1.5 °C and 2 above pre-industrial (1861−1890) on mean temperature precipitation as well intra-seasonal extremes over Greater Horn Africa. used a large, 25-member regional climate model ensemble from Coordinated Regional Downscaling Experiment show that, compared to control period 1971−2000, annual near-surface is projected increase by more than 1 most parts Africa, under GWLs respectively. The highest increases are in northern...
Abstract This study examines the effects of 1.5 °C and 2 global warming levels (GWLs) on intra-seasonal rainfall characteristics over Greater Horn Africa. The impacts are analysed based outputs a 25-member regional multi-model ensemble from Coordinated Regional Climate Downscaling Experiment project. climate models were driven by Coupled Model Intercomparison Project Phase 5 Global Models for historical future (RCP8.5) periods. We analyse three major seasons region, namely March–May,...
While conventional weather forecasts focus on meteorological thresholds for extreme events, Impact-Based Forecasts (IBF) integrate information about the potential severity of impacts with their likelihood occurrence. As IBF provides an indication local risk, there is increasing uptake this approach globally. Despite vulnerability West Africa to severe weather, and benefits such a risk-based informing disaster risk reduction, remains rarely used in region. To meet need, three national...
Forecasts on sub-seasonal to seasonal (S2S) timescales have huge potential aid preparedness and disaster risk reduction planning decisions in a variety of sectors. However, realising this depends the provision reliable information that can be appropriately applied decision-making context users. This study describes African SWIFT (Science for Weather Information Forecasting Techniques) forecasting testbed which brings together researchers, forecast producers users from range UK institutions....
This study describes the verification of Wind Atlas Analysis and Application program (WAsP) modelled average wind speeds in a complex terrain. WAsP model was run using data collected at 3 masts: Kalkumpei, Nyiru Sirima cup anemometers vanes for entire 2009 calendar year verified by WindTracer LIDAR (light detection ranging) 2 weeks from 11th to 24th July 2009. Evaluating mean speed map showed that station provides best over farm domain with difference 0.16 m/s, root square error 0.85 m/s...

Abstract Testbeds have become integral to advancing the transfer of knowledge and capabilities from research operational weather forecasting in many parts world. The first high-impact testbed tropical Africa was recently carried out through African Science for Weather Information Forecasting Techniques (SWIFT) program, with participation researchers forecasters Senegal, Ghana, Nigeria, Kenya, United Kingdom, international pan-African organizations. aims were trial new nowcasting products...
This paper provides an early career researchers (ECRs) perspective on major challenges and opportunities that arise in the study understanding of, provision of regional information for Climate, Weather Hydrological (CWH) extreme events. emerged from discussions three-day Young Earth System Scientists - Hydrologic Society (YESS-YHS) workshop, which was conjointly held with Global Energy Water Exchanges (GEWEX) Open Science Conference. In this we discuss three possible ways forward field: a...
This paper identifies fundamental issues which prevent the effective uptake of climate information services in Nigeria. We propose solutions involve extension short-range (1 to 5 days) forecasts beyond that medium-range (7 15 timescales through operational use current forecast data as well improve collaboration and communication with users. Using newly available provide seamless from short-term sub-seasonal timescales, we examine evidence determine if demand-led sub-seasonal-to-seasonal...
