 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.

The Arctic Oscillation (AO) refers to an atmospheric circulation pattern over the mid-to-high latitudes of the Northern Hemisphere. The most obvious reflection of the phase of this oscillation is the north-to-south location of the storm-steering, mid-latitude jet stream.

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.

Wondering how strong any potential El Niño might be this winter? Maybe you should look to the South Pacific for clues. 

MJO impacts on 2017-18 winter

How this winter's temperature swings may have been partially driven by the Madden Julian Oscillation or MJO.  

In this activity, students examine global climate model output and consider the potential impact of global warming on tropical cyclone initiation and evolution. As a follow-up, students read two short articles on the connection between hurricanes and global warming and discuss these articles in context of what they have learned from model output.
