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 per cent... La Ni a events tend to follow El Ni os; the 2006-07 El Ni o weakened somewhat earlier than normal giving time for a La Ni a to begin developing during the critical March to June period; and 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... BOM climate meteorologist Grant Beard says that although central to eastern Pacific sea-surface temperatures have remained close to average during March, following the rapid cooling that took place during January and February, the remaining large pool of cold sub-surface water could indicate a La Ni a event...

Australia finished 2007 with nearly average rainfalls the timing of these events meant that many winter crops missed out on in-season falls By Rebecca Thyer When it comes to rain, timing is everything, something that many growers can attest to after missing out on crucial in-season rains last year, only to have them fall at harvest time... Dr David Jones, head of climate analysis at the Bureau of Meteorology's (BoM) National Climate Centre, says the irony of 2007 is that the year as a whole ended with almost average rainfalls across the eastern and southern states - it just fell at the wrong time. ".. Dr Jones says the dry conditions were not linked to the late onset of La Ni a, a weather event normally associated with increased rainfall during winter. "..
