The document discusses the 2011 La Niña weather phenomenon. La Niña is a climate pattern characterized by cooler than average sea surface temperatures in the eastern central Pacific. During the 2011 La Niña, there were several major effects around the world, including drought in the Horn of Africa, water shortages in the South Pacific islands, and an abnormal number of typhoons in the Philippines and western Pacific. Understanding events like La Niña helps predict weather changes and allow preparations for potentially dangerous impacts on many parts of the world.
