Africa floods linked to 'La Nina' weather in Pacific


El Nino & La Nina Map

GENEVA (AFP)-Severe flooding caused by torrential rains stretching across Africa is probably linked to the "La Nina" weather pattern thousands of mile away in the Pacific. The World Meteorological Organisation warned in July that the combination of tropical wind patterns over the Pacific Ocean and cooler than normal sea temperatures off western Latin America could have a "planetary" impact. The link between "La Nina" and flooding in western Africa has been closely studied since the 1990s. "We have found a very close relationship between La Nina and the phenomenon of flooding in West Africa. It was therefore very probable that a rather rainy season would occur in the region extending from Sudan in the east to Senegal in the west."
