Following on my previous post, “Jason and the Argo Notes”, just a couple of graphs in passing:
Figure 1. Argo surface temperatures, northern hemisphere. Colors show the latitude of the floats, from red at the Equator to blue in the north. Click on image for full size version. UPDATE: several readers pointed out that the x-axis is years, not “Latitude” as it is incorrectly labeled.
Lots of interesting stuff there. I note that in the northern hemisphere, you can see how the limit on the ocean temperature affects the areas a bit further away from the equator (yellow and green). Those it only clips in the summer, while at the equator it affects temperatures for much of the year.
Also, the shape of the annual swings is interesting. The high temperature in the summer comes to a sharp peak and drops quickly, while the winters drop and change slowly, leading to a rounded shape.
Always more to learn,
