摘要：The present study was to correlate the variation of the maximum daily rainfallwith El Niño intensity index in the state of Mato Grosso do Sul used data from 37 stationswith 30 years of rainfall data and 55 stations with data ranging from 20 to 29 years, andthroughout this series between the years 1977 to 2006. The monthly data on the intensity of weather phenomena El Niño and La Niña were obtained from the National Weather Service of the United States (NOAA – National Weather Service), which were related to the maximum daily precipitation data in order to describe the evolution of the pathwayprecipitation under the influence of phenomena. In the period 1977 to 2006 the average monthly Niño índex ranged between -1,1°C and 1,3°C, variations considered moderate, with some variations considered strong in the years 1982 (2.3°C), 1983 (2.3°C), 1988 (-1.9°C), 1991 (1.6°C), 1992 (1,8°C), 1997 (2.5°C), 1998 (2.3°C), 1999/2000 (-1.6°C) and 2002 (1.5°C). In general, the maximum daily rainfall of each year grew extremeepisodes of El Niño and varied little in the episodes of La Niña. It is concluded that the El Niño and La Niña rainfall causing evident effects on the state of Mato Grosso do Sul, but El Nino is more powerful than the La Niña rainfall in the State of Mato Grosso do Sul.
