Sydney (UNA-OIC) – Australia’s Bureau of Meteorology said Tuesday that the weather phenomenon known as ‘La Niña’ has developed for the second consecutive year in the Pacific Ocean.
La Niña is a climatic pattern that occurs over the Pacific Ocean and has global impacts on weather, wildfires, ecosystems, and economies. The meteorological phenomenon occurs every two to seven years, on average, but they don’t occur on a regular schedule.
The second half of 2020 saw the emergence of a moderate to strong La Niña event causing extreme weather in many parts of the world, according to the World Meteorological Organization (WMO).
The 2020–2021 La Niña episode puts some countries in Southern Africa, the Greater Horn of Africa, Asia and the Pacific at high risk of incurring agricultural losses and seeing food insecurity conditions worsen, the Food and Agriculture Organization (FAO) reported, adding that these countries should be prioritized for further monitoring, analysis and early action.
