Sea pumps to create rain using windmills to control weather?

+0
−0

I'd love some science advice and facts for this question:

If they use wind power to bring up water from the ocean in the day time and spray it on prevailing winds going into land (i.e. 10-15 km from the coast using 200m high fountains), can they make it rain more in arid regions? What weather control can be done by bringing up water from the sea?

Here are some maths (probably wrong):

1 Kilowatt-hour lifts 1 m3 by 100 meters,

An average 5MW output wind turbine can generate 10 Gigawatt hours per year and costs a million dollars.

An average wind turbine can therefore lift 10 cubic kilometers of water every year by 100 meters.

For a billion dollars, Australia can therefore lift 10,000 cubic kilometers of water into the air and perhaps send 100 cubic kilometers of water vapor into sky above Australia.

So, if humans can atomize that much water into the atmosphere every year, for regions like Australia and the Sahara... Can't we give them a lot of clouds and rain? Essentially, wouldn't that easly humidify the coastal air to 100% year-round and generate huge masses of humid air which would cause major rainfalls?

NaCl is about 60 grams, H20 is 18 g, Air averages to 29 g, I found that salt vapor doesnt travel very far from the coast:
