Just noticed that the SST's off WA are warming fairly quickly, so I thought I'd start a thread to keep an eye on this.

They've been going up and down a bit, they were cooler for a while there in August. There's a small area of cooler SST's off the west coast between Perth and Cape Leeuwin and that bit is slowly disappearing. How this will affect our summer weather, I don't know.

There seems to have been heating nearer the coast in the area of the Leeuwin current. The cold anomaly in the mid Indian ocean isn't that pronounced - at least not from the WZ chart.

I have heard Bom people speculate about the warmer waters near the coast - whether it increases the moisture enveloped in cold fronts as they approach perhaps at the expense of warmer temps than might otherwise occur.

Last week's anomalies:


Compared to this week's anomalies:


The SST's off QLD are rising now. That area to the northwest of WA continues to warm.

I find that cold patch directly off of Perth interesting, there is the deep channel not far off of Perth perhaps that influences the map?

http://www.flickr.com/photos/66306358@N03/6188131721/in/photostream This outlines what i mean, i found it to be more alike than i would have actually guessed. My thoughts were some sort of water vorticies, but you would expect warm water not cool. I seem to recall that there is a gigantic whirl pool off of Perth to the NW slightly but i haven't read about that for a while now. Just seems coincidental.
