The Big Wet ...

... was very big indeed. Australian wet weather over 2010-11 was big enough to lower global sea levels by 7mm (temporarily, that is)!

The article below explains what went on:

That is truly amazing.

A quick back of envelope calculation: Area of Oz=7,690,000km^2 area of oceans=361,000,000 So the oceans cover 47 time more area than Oz so the average increase in water depth across the country= 47*7= 329mm. Just try to picture the whole country covered with 33cm of water. No wonder all the lakes are full! Of course not all that water was on the surface, much of it has gone into ground water (how much I wonder?)

What about what's in my rainwater tanks.
