It took me three goes and a nights sleep to get the name right
I was talking to someone yesterday about my negativity when it comes to other people's dogmas. She said I should leave it out.
But what am I supposed to do when confronted with this: …
Quote from the Little Shop of Physics under the heading of Theory (In science the word "theory" means "catch 'em young and teach 'em wrong and they'll be dumb their whole life long.)
It is very warm along and around the equator, a region we call the tropics, since the sun shines so directly there throughout the year.
[This in itself is quite correct half the time. Not like summer at the Poles where it is true all the time. Where is goes wrong is in the amount of albedo the tropics has.]
As you know, when air is heated, it expands becoming less dense and more buoyant, that is, it becomes very light and wants to float.
Since pressure in the atmosphere decreases as you go up, the rising warm bubble of air expands adiabatically, doing work to push away surrounding air and therefore cooling as it rises and leaving a void of low pressure behind.
As the rising air cools, the water vapour in it also cools and then condenses into cloud droplets, which eventually collide with one another, coalescing to form bigger and bigger droplets until the droplets get so big that they fall out of the cloud as rain.
Since it is always so warm in the tropics, this kind of rising motion that forms rain is going on all the time, supplying water to the rainforests."
This is where I stopped reading as it was tying me up in knots. How much more so the desperately simple minds of puddings whose only claim to fame is that they can fill out forms correctly?
First of all, the rain isn't warm when it deliquesces. The tropopause in the tropics is higher than anywhere else. And the water at the top of it is super-cool.
Furthermore it is this super-cool water that is reflecting sunlight back into space.
My point being that the premise about the ITCZ is based on fallacy.
Were we to teach future meteorologists facts not fancies, would they find themselves other jobs or go on to become visionaries instead of hacks?]
The converging air cannot go sideways or down through the ground, so it is forced to rise once more. The latitudinal band in which this occurs is called the ITCZ or Intertropical Convergence Zone, because it is where convergence happens in the the tropics. This convergence line is not always on the equator, though. It moves to the north and south as the seasons change, following the location of most intense sunshine.
[I highlighted the only fact in the essay in bold. The rest is absolute nonsense if you only take the time to think about it. Start off with a bad attitude and criticise it. I left one more gaping flaw for you to expose.]
