Turbulence, Closure and Parameterization

The Science of Doom

In Latent heat and Parameterization I showed a formula for calculating latent heat transfer from the surface into the atmosphere, as well as the “real” formula. The parameterized version has horizontal wind speed x humidity difference (between the surface and some reference height in the atmosphere, typically 10m) x “a coefficient”.

One commenter asked:

Why do we expect that vertical transport of water vapor to vary linearly with horizontal wind speed? Is this standard turbulent mixing?

The simple answer is “almost yes”. But as someone famously said, make it simple, but not too simple.

Charting a course between too simple and too hard is a challenge with this subject. By contrast, radiative physics is a cakewalk. I’ll begin with some preamble and eventually get to the destination.

There’s a set of equations describing motion of fluids and what they do is conserve momentum in 3 directions (x,y,z) – these are the Navier-Stokes equations, and…

Local sea level rose 4 inches in the Northeast US and Newfoundland, global warming not to blame

Watts Up With That?

From the University of Arizona:

Sea level spiked for 2 years along northeastern North America

fast-sea-level-rise By using historical data from the 40 tide gauges shown on this map, University of Arizona geoscientist Paul Goddard and his colleagues figured out that sea level rose four inches (100 mm) from New York to Newfoundland (red dots) in 2009 and 2010. Gauges from New York south to Cape Hatteras (pink dots) showed a smaller spike in sea level for the same time period. No sea level spike was recorded on the gauges (white dots) south of Cape Hatteras. Credit: Paul Goddard/ University of Arizona department of geosciences

Sea levels from New York to Newfoundland jumped up about four inches in 2009 and 2010 because ocean circulation changed, a University of Arizona-led team reports in an upcoming issue of Nature Communications.

The team was the first to document that the extreme increase in…

Barack Obama Goes Full Stalin

Real Science

The level of Soviet style criminal activity at the White House has reached spectacular new lows. On February 20, The White House sent out this E-mail announcing that they were going to start attacking individual scientists who dissented from the White House global warming agenda.

A few hours later, this E-mail was sent out to a large group of prominent skeptics. The author used a stolen identity of Harvard’s Dr. Willie Soon, and obtained the list of skeptic E-mails via hacking. The E-mail pre-announced an attack by the press on an individual scientist.

Today they sent out another E-mail using Dr. Soon’s stolen identity, pre-announcing newspaper attacks on other prominent skeptics.

This behavior by the White House, coordinated with the press corps, is straight out of the Stalin era Soviet Union.

It shouldn’t come as a surprise. The White House adopted Soviet era themes from day one.

Shell wants you to walk

Green Hell Blog

At the annual Rentseekers Ball (aka the Wall Street Journal’s ECO:nomics Conference), Royal Dutch Shell gave attendees room-warming gifts — pedometers, with a note that was headlined “Take the First Step.” If they want us to reduce greenhouse gas emissions so much, why do they sell us gasoline?

Mitigating CO2 emissions: a busted flush?

Climate Etc.

by Michael Kelly

One graph I caught up with this week has convinced me that climate change mitigation by supressing carbon dioxide emissions is a busted flush that history will look back on with great ridicule, even if the worst of the climate alarmist predictions come to pass.

Canada: Climate Extremists a credible threat

Watts Up With That?

Guardian / leaked Canadian Government memo

Greenpeace: too stupid to realize that hot balloon photo op is powered by fossil fuel Greenpeace: too stupid to realize that hot balloon photo op is powered by fossil fuel

Story submission by Eric Worrall

The Guardian has published excerpts of what it claims is an internal Canadian government memo, which suggests that the Canadian government is far more worried about Climate extremists, than Climate Change.

According to the Guardian;

“The US security establishment views climate change as real and a dangerous threat to national security. But Canada takes a very different view, according to a secret intelligence memo prepared by the Royal Canadian Mounted Police (RCMP).

The memo, stamped “Canadian eyes only”, repeatedly casts doubt on the causes of climate change – the burning of fossil fuels – and its potential threat.

The 44-page intelligence assessment of Canada’s environmental protest movement was prepared for the government of Stephen Harper, who is expected to roll out new anti-terror legislation.
