El Niño is a well known-weather phenomenon. In Ecuador and Peru, fisherman knew about the phenomenon long before it was well known because their fishing would be very poor during El Niño conditions
Normally Peru and Ecuador have a remarkable fishery because there is a prominent upwelling along the coast which produces plantonic blooms that feed the entire ecosystem. This upwelling is driven by surface wind conditions. From your knowledge of currents and wind conditions, which of the following happens during El Niño conditions in this area? A) The winds shift from prevailing southwesterlies to stagnant, doldrum conditions during El Niño. B) The winds shift from south to north, along the coast, to west to east, across the coast. C) The winds change from east to west (offshore flow) to onshore flow or weak winds during El Niño conditions. D) The winds shift from west to east (onshore flow) to offshore flow (east to west) during El Niño conditions.
