The latest information on El Nino
11 November 2009
An El Niño event has been established. Please visit the Hong Kong Observatory website (http://www.hko.gov.hk/lrf/enso/enso.htm) for further details.
El Niño is characterized by above-normal sea surface temperatures over the central to eastern equatorial Pacific Ocean off the Peruvian coast. It usually peaks around Christmas, hence the name of the phenomenon (Spanish for "the little boy" or "the Christ Child").
