On the shifting tropical rainfall south from the Kimberley, I've got an idea for a scheme worthy of Macroscien, but I'm not going to illustrate it with screen grabs.
No pipeline involved and the water doesn't end up in Perth.
The last couple of years of drought are claimed to be due to the Indian Ocean Dipole moving the warm water toward Africa, reducing evaporation off northwest WA, resulting in drier winds flowing over central Australia and further east. So our problem is, how can we increase the evaporation?
Solution is using the abundant sunshine in the north to power pumps that take ocean water and just spray it up into the air off the coast. Lots of droplets in the air have a much bigger surface area than the undisturbed ocean, so the evaporation rate is increased. The slightly wetter air can then move across the continent and drop its moisture over the NT, Qld and northern NSW. Fat cattle all round! Even at Dalby
That sounds pretty good in therory.
Two things though;
- How much volume would you need to be pumping into the air.
- Pollies wouldn't consider it as there is no immediate result once you turn the pumps on.
Maybe you should get Gretta onto promoting it.
