Flavors of Climate variability: El Nino, La Nina and Recurring Jet Stream patterns

Gerry Bell, NOAA/CPC, College Park, MD


"This presentation is designed to introduce several major climate phenomena that strongly influence our weather throughout the year, sometimes for decades at a time. Some of these climate patterns are linked to recurring jet stream patterns and are called teleconnections. Another climate phenomenon (El Niño) is linked to tropical Pacific sea surface temperature and rainfall patterns, while yet another is linked to Atlantic sea surface temperature patterns. The nature of these various climate phenomena will be described, and their importance for weather in the U.S. and elsewhere will be shown.  The manner in which various combinations of climate factors interact, along with aspects of their predictability, will also be discussed."
