In early June 2010, NOAA’s Climate Prediction Center reported that the ocean and atmosphere conditions across the Pacific were favorable for the development of a La Niña episode.

The early wet season of 2010 was typical of La Niña, with rainfall in December 2010 between 200 and 400 percent above normal in much of Queensland, according to the Australian Bureau of Meteorology.

 Researchers at NOAA’s National Climatic Data Center collaborate with tropical cyclone centers and scientific agencies around the world to assemble and maintain the International Best Track Archive for Climate Stewardship (IBTrACS), an inventory of tropical cyclones.

The Pacific-North American teleconnection pattern influences regional weather by affecting the strength and location of the East Asian jet stream, and subsequently, the weather it delivers to North America.

Over the span of days or weeks, the strength of surface air pressure over the North Atlantic seesaws between Iceland and the Azores Islands. The shifting pressure reflects changes in atmospheric circulation that have a big impact on mid-latitude weather in the U.S. and Europe.
