  From part 0 Finally, we find that the wind power in the tropical Pacific is subject to significant decadal variations, especially related to the climate shift of the late 0000s (e.g. Guilderson and Schrag, 0000; Fedorov and Philander, 0000). Thus, our results indicate that accurate estimates of the global wind power, and hence of the net wind work on the ocean general circulation, require a careful consideration of the tropical ocean.
