The unusual rainfall extended into northwestern South America Ecuador and Peru. The disruption in the atmosphere impacts rainfall throughout the world.
In the United States, the strongest change in rainfall is in the southeast, the region closest to the pool of warm Pacific water. The atmosphere cools in response to the cold ocean surface, and less water evaporates. The cooler, dry air is dense. As a result, less rain falls over the eastern Pacific.
Ecuador, Peru, and the southeastern United States are correspondingly dry. Animals Wild Cities Wild parakeets have taken a liking to London. Animals Wild Cities Morocco has 3 million stray dogs. Meet the people trying to help. Animals Whales eat three times more than previously thought.

Tides and Oceans. The Short Answer:. During this time, unusual winds cause warm surface water from the equator to move east, toward Central and South America. Convection above warmer surface waters bring increased precipitation. Rainfall increases drastically in Ecuador and northern Peru, contributing to coastal flooding and erosion.
Rains and flood s may destroy homes, schools, hospitals, and businesses. They also limit transportation and destroy crop s. Agriculture , which depends on water for irrigation , is threatened. Global atmospheric circulation is the large-scale movement of air that helps distribute thermal energy heat across the surface of the Earth. The eastward movement of oceanic and atmospheric heat sources cause unusually severe winter weather at the higher latitude s of North and South America.
Regions as far north as the U. These strong temperature increases caused severe climatic changes: Australia experienced harsh drought conditions; typhoon s occurred in Tahiti; and record rainfall and flooding hit central Chile. The west coast of North America was unusually stormy during the winter season, and fish catches were dramatically reduced from Chile to Alaska.
The event produced drought conditions in Indonesia, Malaysia, and the Philippines. Peru experienced very heavy rains and severe flooding. Disease s thrive in communities devastate d by natural hazard s such as flood or drought. Modoki is a Japanese word meaning "similar, but different. These buoy s measure ocean and air temperatures, currents, winds, and humidity.
The buoys are located at about 70 locations in the southern Pacific Ocean, from the Galapagos Islands to Australia. These buoys transmit data daily to researchers and forecast ers around the world.
The weather pattern brought unseasonably warm weather to the normally chilly coastal town. Excess nitrates can choke freshwater ecosystems. Oceanic Nino Index. Excess phosphates can choke freshwater ecosystems.
