Columbia Researchers Provide New Evidence on the Reliability of Climate Modeling
The Hadley circulation, or Hadley cell -- a worldwide tropical atmospheric circulation pattern that occurs due to uneven solar heating at different latitudes surrounding the equator -- causes air around the equator to rise to about 10-15 kilometers, flow poleward (toward the North Pole above the equator, the South Pole below the equator), descend in the subtropics, and then flow back to the equator along the Earth's surface. This circulation is widely studied by climate scientists because it controls precipitation in the subtropics and also creates a region called the intertropical convergence zone, producing a band of major, highly-precipitative storms.
[...] Historically, climate models have shown a progressive weakening of the Hadley cell in the Northern Hemisphere. Over the past four decades reanalyses, which combine models with observational and satellite data, have shown just the opposite -- a strengthening of the Hadley circulation in the Northern Hemisphere.
[...] The difference in trends between models and reanalyses poses a problem that goes far beyond whether the Hadley cell is going to weaken or strengthen; the inconsistency itself is a major concern for scientists. Reanalyses are used to validate the reliability of climate models -- if the two disagree, that means that either the models or reanalyses are flawed.
[...] To understand which data was correct -- the models or the reanalyses -- they had to compare the systems using a purely observational metric, untainted by any model or simulation. In this case, precipitation served as an observational proxy for latent heating since it is equal to the net latent heating in the atmospheric column. This observational data revealed that the artifact, or flaw, is in the reanalyses -- confirming that the model projections for the future climate are, in fact, correct.
The paper's findings support previous conclusions drawn from a variety of models -- the Hadley circulation is weakening.

Apparently not.
Title of front page post: New Evidence on the Reliability of Climate Modeling
From TFS:
Not sure what the confusion is here.
But I'll explain, and I'll use small words so you'll be sure to understand, you warthog-faced buffoons:
There is new evidence (that means data/information that we didn't have before) concerning how reliable climate models may be (that means whether or not such models get it right or not).
Are you following along so far? Maybe you should read that last sentence again to make sure you understand. It's okay. I'll wait.
Okay. The new evidence is "confirming that the model projections for the future climate are, in fact, correct." This means that yes, the projections (that means estimates about the future) are correct (that means they're right).
Are we clear now, or do we need to dumb this down from fourth grade to second?

As your brain is demonstrably too small to handle "fourth grade" small words, do try again with monosyllables. Grunts and yelps shall be within your capability and a closer fit to your type of thought process.

Your mom didn't think so.
She was so pleased, she even introduced me to your girlfriend. Okay. That's a lie. We both know you don't have any sexual partners for which your don't pay cash up front. At least that's what your mom said as I was getting dressed.
Yeah, this is about your level, isn't it?

Keep your filthy mitts off my cheese steak, you cad! You poltroon!
I've painted that cheese steak 400 times with hot-buttered motor oil and took it with me to meet the Queen!
Seven horny stalagmites made me rich! So I bought the CIA and they will bury you.
Believe in the great avocado, do you? I eat your avocado and raise you a chimichanga!

See the difference now, friend?

The projections are correct is a very nebulous concept, barring a time machine. Not that I care.
