Past outlook (January 11th) |
Current outlook (February 21st) |
|---|---|
| PACIFIC OCEAN: Cool INDIAN OCEAN: Neutral RAINFALL: Wetter to slightly wetter TEMPERATURE: No clear signal |
PACIFIC OCEAN: Cool (weak La Niña) INDIAN OCEAN: Slightly cool RAINFALL: Average/slightly wetter TEMPERATURE: No clear signal |
30 Day Moving SOI
The SOI remains strongly positive indicating that the Walker Circulation is enhanced and that the pressure at Darwin is lower than at Tahiti (an indicator of La Niña conditions).

Air Pressure (MSLP last 30 days NOAA)
Air Presssure (MSLP last 30 days NOAA). Average (top), anomaly (below). Pressure has been lower through Indonesia, off WA and below Tasmania. Pressure was slightly higher off the coast of NSW and higher off SW WA.

NOAA/NESDIS SST Anomaly (degrees C), 4/4/2011
The equatorial Pacific continues to remain cooler than average (below La Niña thresholds), but is showing a warming trend. The Indian ocean off WA is warm, the Coral Sea is rewarming after being cooled by cyclone Yasi.

OLR Totals
Victoria has been slightly cloudier for the last 30 days. There is large amounts of cloud off NW WA. Cloudiness continues to remain below average near the dateline at the equator (brown) often an indicator for La Niña.
