What are the impacts of La Nina?

La Niña reduces wind shear—the change in winds between the surface and the upper levels of the atmosphere—allowing hurricanes to grow. The likelihood of La Niña was factored into NOAA’s August outlook for the Atlantic hurricane season, which favored an “extremely active” season.

When was the last period of La Nina?

However, in the historical record the interval between events has varied from 2 to 7 years. 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, 1995,1998, 2007, 2010.

Does La Nina mean more rain?

Rain clouds normally form over warm ocean water. La Niña blows all of this warm water to the western Pacific. This means that places like Indonesia and Australia can get much more rain than usual. However, the cold water in the eastern Pacific causes less rain clouds to form there.

How often is La Nina?

every 3 to 5 yearsTypically, La Nina events occur every 3 to 5 years or so, but on occasion can occur over successive years. La Nina represents the cool phase of the El Nino/Southern Oscillation (ENSO) cycle.

What is an effect of La Niña?

La Niña is a phenomenon that describes cooler than normal ocean surface temperatures in the Eastern and Central Pacific Ocean, regions close to the equator off the west coast of South America. In some parts of the world, La Niña causes increased rainfall, while in other regions, it causes extreme dry conditions.
