It is not the sinking that causes the air to become drier.

It is the fact that the cold air at high altitude warms much as it sinks to lower altitude.

The RH of a warming gas will decrease, radically, even though no water is added to the system.

 

Please keep in mind that the absolute amount of water vapor in the air remains the same in this example, although of course the amount of air under discussion will expand.

 

If you were to add water vapor from some other source, then this would change the validity of this example.

 

 

You didn't mention pressure systems either. Oh well, how sad, never mind.

Well, of course, sinking air will be compressed and and this compression will cause warming.

This is not a sad thing.

It's just basic physics.

But away from the OP topic. Ta ta.

As the heat increases there are convection currents this moves the air upwards, as the air moves upwards it gets cooler, at a threshold temperature & depending on presence of condensation nuclei (bacteria, sugar alcohols, dust particles, etc.) it will then condense to form rain (phase changes as mentioned by GammaGlobulin).  Hence, the rain in the tropical regions.

 

The reason is humidity is less in the middle eastern countries is that they get very infrequent rain due to the air already having had most of its water rained out over the tropical (equatorial) regions, this air will have a lot less water vapour then travels & descends at the Tropics of Cancer & Capricorn.  This is why there is less humidity in the Middle East & any countries at similar latitudes, the humidity is lower because it has condensed somewhere else.

All this movement is due to global convection currents forming the various convection cell such as the Hadley cells.  All is driven by the Sun's radiation output and the absorptive capacities of the various greenhouse gases & how their wavelengths (lambda) change when re-emitted after ground absorption.

 

Also because it is a lot hotter than most places in the world

Rest assured, I will be taking another 2-months break, beginning in about an hour....

So, please keep your socks on...til then...

 

What happened to that so called promise?

Soon...Very soon....Please keep your socks on, Sir.

Also, you must admit that..at least, I have not added any new confounding topics.

You must admit....

I never said I was a meteorologist.

I don't like all those changing variables in an open system.

I prefer the laboratory.

Still, the science is the same.

Ok then. Enjoy the lab rats.

 

 

yeah, you've got Predators for sure...

I use THREE AirCons and will add one dehumidifier to the mix.

 

My rate of dehumidification will be even higher.

 

I intend to remove about 13 liters of condensate per hour.

 

Can you beat that?

 

 

So very dry....she is....

 

 

If I were a racist.....

THEN>.......

 

How could I love Tracy Chapman even more than LIFE ITSELF....?????

 

Riddle me THIS....please.....

 

Can you?

 

I would give up my life for Tracy......

 

She is black, through in through....

 

And, I am some sort of white dude, who has never even sung a decent song....

 

Go figure.....

 

Any thoughts.....????

She is no dummy, for sure....

 

TUFTS UNIVERSITY...for sure.....

She has a big brain......

 

This is why I love her.

 

"And there ain't no more to say...."

 

I recall listening to her music, back in 1989, or 1990, or 1991, or 1992....while driving from....

 

NAPLES FLA

to Philly......

 

Driving in a Jag XJ6.....What a beast.....6000 pounds, if an ounce.....maybe 5000, as I recall....but when all packed up...6000 pounds....

 

All the way, it was Chapman......

 

And, it was very SMOOTH Driving, all the way.....

 

Dig.....

 

Didn't get stopped by the Cops, once......

 

Tracy was the charm....

 

Even through Georgia .....

 

Believe me.....

 

Telling it like is was, back then....

 

 

Humidity has increased recently but not to uncomfortable levels. I have experienced much  worse living in other places,  eg Lagos and Jeddah.

I'll take "Fast Car" for 1000 THB, Tracy Chapman
