|The Northern Oscillation
The NOI (extratropical-based Northern Oscillation Index) and
its analog, the SOI* (extratropical-bassed Southern Oscillation Index) are new
indices of midlatitude climate fluctuations that show interesting relationships with fluctuations in marine ecosystems and populations.
They reflect the variability in
equatorial and extratropical teleconnections and represent a wide range of
local and remote climate signals. The indices are
counterparts to the traditional SOI (Southern Oscillation Index) that relate variability
in the atmospheric forcing of climate change in northern and southern midlatitude hemisphere

Note: In earlier editions of the manuscript, the NOI was known as NOIx and SOI* was known as SOIx.
