This contribution aims to investigate the influence of monthly total rainfall variations on malaria transmission in Limpopo Province. For this purpose, was interpolated from daily data weather stations. Annual and seasonal trends, as well cross-correlation analyses, were performed time series cases five districts Province for period 1998 2017. The analysis indicated that an average 629.5 mm received over study. has annual variation about 0.46%. Rainfall amount varied within districts, with...
This research study evaluated the projected future climate and anticipated impacts on water-linked sectors transboundary Limpopo River Basin (LRB) with a focus South Africa. Streamflow was simulated from two CORDEX-Africa regional models (RCMs) forced by 5th phase of Coupled Model Inter-Comparison Project (CMIP5) Global Climate Models (GCMs), namely, CanESM2m IPSL-CM5A-MR models. Three projection time intervals were considered spanning 2006 to 2099 delineated as follows: current climatology...
Motivated by the risks posed global warming, historical trends and future projections of near-surface temperature in South Africa have been investigated a number previous studies. These studies included assessment average temperatures as well extremes. In this study, minimum maximum extreme indices were critically comparing quality-controlled station observations with downscaled model projections. Because climate models are only means generating warming projections, critical point comparison...
Among the projected effects of climate change, water resources are at center matrix. Certainly, southern African is changing, consequently, localized studies needed to determine magnitude anticipated changes for effective adaptation. Utilizing historical observation data over Olifants River Catchment, we examined trends in temperature and rainfall period 1976–2019. In addition, future change projections under RCP 4.5 8.5 scenarios two time periods 2036–2065 (near future) 2066–2095 (far were...
Abstract Forecast skill of three subseasonal‐to‐seasonal models and their ensemble mean outputs are evaluated in predicting the surface minimum maximum temperatures at subseasonal timescales over South Africa. Three scores (correlation anomaly, root‐mean‐square error, Taylor diagrams) used to evaluate models. It is established that considered here have both timescales. The correlation anomaly indicates multimodel outperforms individual for day 1–14, 11–30, full calendar month during December...
Background: Malaria, though curable, continues to be a major health and socioeconomic challenge. Malaria cases have been on the rise for last two years in malaria-endemic region of South Africa. Thulamela Municipality Limpopo, Africa, which falls within several municipalities at Vhembe district that are affected by malaria. About 33,448 malaria were reported over period 20 (1998 January-2018 December). Objective: The study aims determine influence climate spatiotemporal distribution decades...
