South Pacific Hot Spot

You may remember the article about news of a hot spot in the Pacific Ocean I posted recently. Well I finally got round to producing a more detailed composite SST map made up from a lot of map tiles for the south Pacific courtesy of NCOF. As you can see it’s certainly quite a blob of warmer than average water which extends to many thousands of square miles to the east of New Zealand. It may not be just quite as warm as it was late last year, but the anomalies still look to be 2 or 3°C above the long term average. It’s not been blamed on global warming or the jet stream (that ribbon of fast moving air high up in the atmosphere) yet, but I’m sure it won’t be long before it is. I still fancy geothermal activity from the Pacific rim of fire as the cause but I may be out on a limb with that notion.
