Hasta La Vista El Nino?
A La Ni�a in 2007?
The chance of a La Ni�a developing in 2007 is thought to be higher than the long-term average (which is about one in five or 20%) because (a) they have a tendency to follow an El Ni�o; (b) the El Ni�o has decayed somewhat earlier than normal thereby giving time for a La Ni�a to begin developing during the critical March to June period; and (c) a large pool of cold sub-surface water remains in the central to eastern tropical Pacific Ocean and is starting to affect surface temperatures in the region. La Ni�a events are generally associated with wetter than normal conditions across much of the eastern half of the country from about autumn. Computer models generally indicate further cooling in the Pacific Ocean.
