El Niño is characterized by the warming of the surface waters in the central and eastern tropical Pacific Ocean. This *replaces* the usual cold Peruvian current, not leads to the appearance of a cold current. Therefore, the statement “Appearance of cold current in East Pacific region” is incorrect.
El Niño is a phenomenon of warm sea surface temperatures in the eastern equatorial Pacific. It is generally associated with weak monsoon in India and reduction in plankton production due to suppressed upwelling of nutrient-rich cold water.
