"Arctic Oscillation Sometimes called the northern hemisphere annular mode, this is the year-to-year variability pf weather patterns at high latitudes in the northern hemisphere" "The two phases of the Arctic Oscillation: Left– Warm Phase; Right– Cold Phase. Notice that storms come ashore in Europe at different latitudes in the two phases. This strongly influences European weather, especially in winter. " (Graph): The Pacific Decadal Oscillation is related to weather over north America "Positive PDO values are usually associated with wetter conditions in the Southwestern United States, while negative PDO values are suggestive of persistent drought in the Southwest." The word 'climate' desn't appear 'til near the end, and then it's in an oblique reference to something else. here's my own background page on the dendroclimatology.... http://www.abelard.org/briefings/dendroclimatogy.php but i'll just work to understand enough to be able to assess the factor analysis... One shudders to think what primary colours it might be written in. -- from Kim Bolton |
