HOME > Monitoring and Data > Monitoring Intraseasonal Oscillations
 
 
The intraseasonal oscillations are a naturally occurring component of our coupled ocean-atmosphere system. They significantly affect the atmospheric circulation throughout the global Tropics and subtropics, and also strongly affect the wintertime jet stream and atmospheric circulation features over the North Pacific and western North America.

As a result, they have an important impact on storminess and temperatures over the U.S. During the summer these oscillations have a modulating effect on hurricane activity in both the Pacific and Atlantic basins. Thus, it is very important to monitor and predict intraseasonal activity, since this activity has profound implications for weather and short-term climate variability through the year.
