La Niña strengthens in the Pacific
A La Niña event is now well established in the Pacific Ocean. All computer models surveyed by the Bureau suggest Pacific Ocean sea surface temperatures (SSTs) will remain above La Niña thresholds through the southern hemisphere spring, with the majority indicating the event will persist into at least early 2011.
La Niña periods are usually, but not always, associated with above normal rainfall during the second half of the year across large parts of Australia, most notably eastern and northern regions. Night time temperatures are historically warmer than average and Tropical Cyclone occurrence for northern Australia is typically higher than normal during the cyclone season (November-April).
