South Africans can look forward to a wet summer
this year, as there is apparently almost no chance of an El Niño phenomenon developing.
This is according to data compiled by the Council for Scientific and Industrial Research (CSIR), which has developed a forecasting technique that is able to estimate the chances of El Niño or La Niña.
The El Niño phenomenon occurs when water around the equator in the Pacific Ocean is warmer than usual. Its twin is La Niña, which is followed by cold weather.
“There is almost no chance for an El Niño this summer,” said Dr Willem Landman from the CSIR’s department for climate study and modelling.
“To tell the truth, the current La Niña will be present throughout summer.”
With the La Niña phenomenon, there is greater chance for a wet season in summer rainfall areas.
“The latest forecasting method shows that the season might start slowly but that mid-summer looks very promising for rain.”
The United Nations said this week that the current La Niña phenomenon would strengthen over the next four to six months. This is due to the strong interaction between the current oceanic and atmospheric conditions and the large area where below-average ocean temperatures are being experienced, according to the World Meteorological Organisation.
It could bring abnormal weather conditions – which range from floods to droughts – to many parts of the world.
Meanwhile, the South African Weather Service forecasts that Gauteng and the eastern parts of the country can look forward to rain this weekend, reports Seugnet Esterhuyse.
According to senior forecaster Evert Scholtz, by the end of the week an upper air trough system will move over the summer rainfall areas, which could lead to thunderstorms on Saturday and Sunday in Gauteng.
Temperatures in Pretoria and Johannesburg will fall by Thursday and Friday and will be accompanied by cloudy weather.
On Friday, there will be a 60% chance of rain in KwaZulu-Natal, Mpumalanga and Gauteng.
Rain will continue over the weekend in the eastern parts of the country, with cloudy weather in Limpopo, Mpumalanga, KwaZulu-Natal and Gauteng.
