But if it develops in the southern hemisphere, which he said is more likely, it will continue until spring. He suspects the warm water pool grows over a matter of years because ocean circulation isn't sufficient to remove the heat. He believes the Indonesian rainfall area moves to the central Pacific when the pool becomes too big or too warm and following west winds cause Indonesian drought. The massive transfer of heat from the ocean to the atmosphere affects world weather systems. He said he's seen no evidence so far it will be bigger than in 1982-83.
Drought occurs in Indonesia, the Philippines and Australia.
Peru has torrential rains, with devastating biological consequences. Alaska may be warmer, southern California wetter and Texas and Florida colder. Changing conditions may occur in places like Brazil and South Africa.
