Trends in climate and ocean conditions as represented by five climatic and oceanic 
(C-O) indices in the eastern North Pacific Ocean from 1922 to 2000. C-0 indices com- 
prise the average spring (Mar-May) coastal sea-surface temperature (SST), cumulative 
amounts of winter and spring (Dec-May) coastal precipitation (PREC), cumulative 
winter (Dec-Mar) coastal Upwelling Index (UI), average winter (Dec-Mar) Atmospheric 
Forcing Index (AFI), and the average winter (Dec-Feb) Northern Oscillation Index 
(NOI). Lines are the loess regression line. Bars are the annual means.
