4 Because climate is non stationary, global and regional climate driver trends are no longer important Source: The University of Alabama in Huntsville
5 Categorical Seasonal Climate monitoring & forecasts (teleconnection indices) Categorical Discrete (e.g. El Niño, Neutral, La Niña) Seasonal Climate 1to 6 months in advance
6 Teleconnection indices El Niño and the Southern Oscillation (ENSO) El Niño La Niña
7 Teleconnection indices El Niño and the Southern Oscillation (ENSO) El Niño Neutral La Niña
8 Worldwide effects of ENSO El Niño La Niña
9 Worldwide effects of ENSO El Niño
10 Teleconnections Map Source:
11 The Arctic Oscillation (AO) Represents the state of atmospheric circulation over the Arctic Positive phase: a belt of strong winds circulating around the North Pole acts to confine colder air across the Polar Region Negative phase: The belt of winds becomes weaker and more distorted allowing an easier southward penetration of colder, arctic air masses and increased storminess into the mid latitudes Source: warming/arctic oscillation ao
