Global warming will weaken winds in the Northern Hemisphere, speed them up downunder!

Now they tell us!

Climate warming to weaken wind power in northern hemisphere, increase in Australia: study

After building 341,000 wind turbines, mostly in the Northern Hemisphere, now climate modelers reveal that winds will decrease in the Northern Hemisphere!

Warming temperatures caused by climate change are set to weaken wind energy in the northern hemisphere, a study shows, lessening the amount of wind power produced for wind farms.

However, the southern hemisphere would see a boost in wind, which could potentially turn north-eastern Australia into an attractive investment for energy companies.

Rush, invest your money now.  The theory called polar amplification has the success rate of a coin toss. Buy a wind farm in NE Australia!

Luckily wind speeds are not also influenced by cloud cover, jet streams, oceans currents, forest growth, atmospheric tides, solar factors, magnetic fields, ozone levels, cosmic rays, or butterflies. Otherwise, this study might be inadequate, uninformed guesswork being used to inform investment decisions!

Key points:

  • Atmosphere instability which creates wind changing in northern hemisphere
  • North-east Australia could become an attractive investment for energy companies
  • At present, there is only one operational wind farm in Queensland

Theoretically, the North Pole is warming and getting closer to temperatures at the equator – which reduces any reason for the wind to go anywhere. So the big question is: will the wind farms be able to change the climate before the wind stops?

The second question:  how did ABC subed’s let that first “key point” pass and what happened to the commas?

Wind usually derives its energy from an instability in the atmosphere, and in the northern hemisphere a major source of that instability is the equator to pole temperature difference,” he said.

“We all know that the tropics are warmer than the Arctic, but because the artic is warming at a much faster rate than the rest of the world — including the tropics and the latitudes — that temperature gradient is lessening.

“That is a well-known phenomenon called polar amplification, or artic amplification.”

Yes, polar amplification is called “polar” for a reason, and it’s wrong. The South Pole is a Pole too. (And Arctic has a c in it for a reason.)

But wait till you hear why winds are speeding up in the Southern Hemisphere:

It found in the southern hemisphere the difference between the average land and sea temperature was increasing, which would push greater wind production.

“As we know most of the southern hemisphere is dominated by ocean, relative to the northern hemisphere,” Professor Karnauskas said.

So in South America, the southern half of Africa and Australia, greenhouse gas warming was expected to increase the temperature over land faster than over the ocean. “The land-sea temperature difference in the southern hemisphere is actually increasing because the land is warming up so rapidly relative to the ocean,” he said.

“So the winds are able to derive greater energy from that temperature difference or instability.”

Call it cartoon science. Two dimensional and with reasoning by the Road Runner.

    Here is another prediction that isn’t going to come true.
