2 El Niño, La Niña El Niño and La Niña are complex weather patterns resulting from variations in ocean temperatures in the Equatorial Pacific. El Niño and La Niña are opposite phases of what is known as the El Niño-Southern Oscillation (ENSO) cycle. Researched on May 10 th 2012

3 Conditions of El Niño, La Niño El Niño causes, Rain and flooding along the Pacific coast.Warm water disrupts food chain of fish, birds, and sea mammals. Tornadoes and thunderstorms in southern US. Fewer than normal hurricanes in the Atlantic.flooding Tornadoesthunderstorms hurricanes La Niño Snow and rain on the west coast. Unusually cold weather in Alaska. Unusually warm weather in the rest of the USA. Drought in the southwest. Higher than normal number of hurricanes in the AtlanticSnowDroughthurricanes Research: Picture: On May 11, 2012http://oceanservice.noaa.gov/facts/ninonina.html

4 Time Period of El Nino, La Nina El Niño and La Niña occur on average every 3 to 5 years. However, in the historical record the interval between events has varied from 2 to 7 years. Research: Picture: niltimbadia.blogspot.com On May 14, 2012

5 EL Niño, La Niña phenomenon's El Nino takes place when warmer than usual sea water exists off the coast of South America. El Nino causes climate effects around the world. According to the National Centers for Environmental Prediction, this century's previous La Niñas began in 1903, 1906, 1909, 1916, 1924, 1928, 1938, 1950, 1954, 1964, 1970, 1973, 1975, 1988, and These events typically continued into the following spring. Since 1975, La Niñas have been only half as frequent as El Niños Research: On May 14, 2012

6 Damage from EL Niño, La Niño The El Niño of 1997/98 saw drought wipe out two thirds of Fijis new sugar cane plantings. Tongas squash exports were reduced to more than half. El Niño induced cyclones, severely damaging its squash industry, already reeling from drought. In December 2001 a damaging cyclone also hit Tonga.

7 Fun facts "El Niño" is Spanish for "the boy child," and is used to refer to the Baby Jesus. The name La Niña ("the girl child") was coined to deliberately represent the opposite of El Niño. Research:http://www.almanac.com/content/el-ni%C3%B1o-and-la-ni%C3%B1
