South African Wave Energy Resource Data

South African Wave Energy Resource Data

A Case Study

May 2013

Dr. J. R. Joubert

Prof. J.L. van Niekerk



An assessment of the South African wave energy resource was conducted through the analysis of measured and modelled wave data. Wave data recorded at wave measuring stations, representative of the various coastal zones of South Africa, was evaluated and it was found that the southwest coast has the highest wave power resource with a median value of wave power of approximately 26 kW/m. A detailed assessment of the spatial distribution of wave power off the southwest coast was conducted and it was found that the average deep-sea resource ranges from 33 kW/m to 41 kW/m. Results of a detailed assessment of the wave

Monday, the U.N.’s Intergovernmental Panel on Climate Change is set to unveil the latest installment in its fifth assessment report. The last one focused on the science behind climate change; this new, 29-page report will detail its impacts, along with what we can do to minimize and adapt to the worst of it. Early indications suggest that the consensus will be cautious, but insistent: The effects of climate change are real, and we’re experiencing them now.

NOAA-led study: Tropical cyclone 'maximum intensity' is shifting toward poles


Researchers find that the average latitude where tropical cyclones achieve maximum intensity has been shifting poleward since 1980

Over the past 30 years, the location where tropical cyclones reach maximum intensity has been shifting toward the poles in both the northern and southern hemispheres at a rate of about 35 miles, or one-half a degree of latitude, per decade according to a new study, The Poleward Migration of the Location of Tropical Cyclone Maximum Intensity, published tomorrow in Nature.

As tropical cyclones move into higher latitudes, some regions closer to the equator
