The North Atlantic warms in response to El Nino events and cools in response to La Nina events, obviously, and the ENSO-induced SST variations (positive and negative) linger in the North Atlantic. In effect, the North Atlantic integrates ENSO. And since the frequency and magnitude of El Nino events have exceeded La Nina events since the mid-1970s, the North Atlantic SST anomalies rise. <br /><br />The South Atlantic is the only ocean basin where heat travels from the pole to the equator, traveling toward the North Atlantic. This contributes to it.Bob Tisdalehttps://www.blogger.com/profile/15462377647970214137noreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-88075254770960779362010-10-28T21:37:02.662-04:002010-10-28T21:37:02.662-04:00Hi I am a university student from UBC, I have been...Hi I am a university student from UBC, I have been analyzing the same data set. I notice a trend between the Pacific and Atlantic Oceans that I cannot account for. It appears as though there is a lag between sea level peaks. Specifically if you plot yearly averages it is easy to see. I was wondering if you have any idea what might be causing the shifting of sea level between the Pacific and the Atlantic?<br />I was thinking it may be the ocean circulation, but the only circulation i could think would cause a difference between the atlantic and pacific would be thermohaline. however this dooesn't make sense as the thermohaline is a slow moving current and would not affect the oceans annually. Any thoughts?jelsligerhttps://www.blogger.com/profile/01914958421425311187noreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-73163985604985774972009-08-01T05:11:23.148-04:002009-08-01T05:11:23.148-04:00Ken Gregory: Give me a day or two to post a video ...Ken Gregory: Give me a day or two to post a video of SSH Residuals that I threw together a couple of weeks ago. I animated weekly SSH maps (2002 to "present") that are available from JPL. The reason I haven't posted it sooner is that JPL unfortunately changed the scale in 2006.Bob Tisdalehttps://www.blogger.com/profile/15462377647970214137noreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-29129974974916672922009-08-01T00:08:24.824-04:002009-08-01T00:08:24.824-04:00The best fit linear trend of sea level rise from J...The best fit linear trend of sea level rise from January 2004 through March 2009 of the Pacific, Atlantic and Indian oceans are 0.15 mm/yr, 0.35 mm/yr and 6.04 mm/yr, respectively. The global rate from January 2004 is 1.52 mm/yr.<br /><br />Can you provide any comment on why the Indian ocean shows such a high rate of sea level rise in recent years compared to the other oceans?Ken Gregoryhttp://www.friendsofscience.org/noreply@blogger.com
