Relative to the long-term upward trend, it tends to be slightly higher in 1st and 4th quarters, and lower in 2nd and 3rd.<br /><br />This is very roughly what one might expect from the fact that most of the ocean is in the southern hemisphere, but the details aren't perfect. The means of residuals for 2nd and 3rd quarters are very similar, whereas I would expect 3rd quarter to be lower than 2nd. climate data analysishttps://www.blogger.com/profile/17052300648198782088noreply@blogger.comtag:blogger.com,1999:blog-28837843.post-65384305345562140502017-11-16T05:03:16.997-08:002017-11-16T05:03:16.997-08:00This comment has been removed by the author.climate data analysishttps://www.blogger.com/profile/17052300648198782088noreply@blogger.comtag:blogger.com,1999:blog-28837843.post-22616794624928821962017-11-14T08:25:19.257-08:002017-11-14T08:25:19.257-08:00DiC, for 1: It takes 4.184 Joules of heat to raise...DiC, for 1: It takes 4.184 Joules of heat to raise one gram of water by 1C.Layzejhttps://www.blogger.com/profile/11346550512734519728noreply@blogger.comtag:blogger.com,1999:blog-28837843.post-18072294437996903332017-11-14T08:07:07.969-08:002017-11-14T08:07:07.969-08:00Some questions:

That is, can the change in joules in a given volume of water or W/m^2 be converted into a change in temperature?<br /><br />2. Heat content seems to have a regular oscillation, based on the chart. Is it possible that the drop in heat content is just normal seasonality?<br /><br />CheersDavid in Calhttps://www.blogger.com/profile/09068188536758619565noreply@blogger.com
