Recharging The Pacific Warm Pool

I’ve moved to WordPress.  This post can now be found at Recharging The Pacific Warm Pool

Note: This is my first attempt at uploading or linking a video I created, so things might get interesting.

INTRODUCTION

In prior posts, I’ve noted that the heat upwelled during El Nino events isn’t all released into the atmosphere, that much of it is returned to the West Pacific and the Pacific Warm Pool where it awaits the next El Nino event. This video of the 1997/98 El Nino and the years that followed should help illustrate the process. I’ve interrupted the flow of the SSH video from JPL to narrate as needed. I also took the opportunity to illustrate and reinforce the lingering effects of the 1997/98 El Nino.

Bill Illis here.

Great movies Bob.

I like the animations and the movies because I think you can gain a lot more insight into what is going on.

I see what you are saying about the lingering effects.

Here is (maybe) a new one for you Bob (I haven't heard this until now).

The Indian Ocean is really the only ocean basin with any sea level rise since 2002 and it is rising very fast at 5 mm per year.

All the other ocean basins are more-or-less flat over the period.

With all the El Ninos over the past 10 years, it looks like a lot of warm ocean water has been pushed into the western pacific and, especially, the Indian Ocean.

I guess that supports the general contention that El Ninos can have long-lasting effects.

Same chart with the seasonal signal removed.

Thanks for the notes, Bill. I started downloading sea level data for the individual basins yesterday for an upcoming post, but got sidetracked. It'll be good to see what correlates with what. I've got family in town for a few days so I'm behind in my posts.

Thanks again.

Regards

The Smith and Reynolds SST Posts DOES NOT LIST ALL SST POSTS. I stopped using ERSST.v2 data for SST when NOAA deleted it from NOMADS early in 2009.

Please use the search feature in the upper left-hand corner of the page for posts on specific subjects.

NOTE: I’ve discovered that some of the links to older posts provide blank pages. While it’s possible to access that post by scrolling through the history, that’s time consuming. There’s a quick fix for the problem, so if you run into an absent post, please advise me. Thanks.
