The information for changes in the Earth's rotation comes from the U.S. Naval Observatory. The information for changes in the Earth's water vapor comes from the International Satellite Cloud Climate Project. You can graph the cloud data using the Climate Scientist Starter Kit and your favorite spreadsheet program.
I don't know what this means yet. As I said, I only just now discovered it. But I wanted to get the information out there so people can see it.
Rest assured that future posts will look into this more deeply.

Probably has to do with the change of moment of inertia, ie the water distribucón the planet.
ReplyDeleteI second indio's comment. If wv increases in the atmosphere, there is a nett movement of mass away from the axis. The moment of inertia of the Earth increases, angular momentum must be conserved, the Earth must slow.
ReplyDeleteHey, I think this is a handy way to assess the increase of MSL.
ReplyDeletePerhaps the first step is to take out a linear trend from the USNO data?
just an idea
