That relates to weather effects as the oscillation frequency is too
high for 30-year climate effects.

"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....

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.
