These weather patterns can last for years and, according to Landman, one cannot accurately predict when these patterns will occur until we are about five to 10 months away from experiencing them.
La Niña occurs when equatorial trade winds — air currents which blow from east to west close to the earth's surface — blow stronger, changing the currents in the water. This forces cooler deep water to rise, cooling the Pacific Ocean and creating rainfall in this area. Southern Africa and other parts of the world are affected by this phenomenon.
“Forecasts for this period — including the next couple of months — seem positive for good rainfall which will lead to slightly below-average temperatures. This is expected to continue into December, January and February. “These oscillations are difficult to predict. We usually find we can experience two consecutive El Niños and we can only say there will be a La Niña 10 months ahead of the main event. These events happen about every five and seven years ...
“When we have La Niña our models predict rainfall, we predict wet weather and that normally turns out to be the case. We expect quite a bit of rain in the next week or so.”
Good news, a rain for a guy like me from Tzaneen means plenty of food to eat and distribute around the country as well❤😃
