I did too.
Does this help at all? http://lmgtfy.com/?q=high+pressure+subsidence
Lol, what a bunch of pretentious assholes you all are. How was I to know I had to google "high pressure" with "subsidence" to get an applicable definition of subsidence? If I should be expected to know the word, I should expect to be able to look up the definition of the word, by itself, and find it among one of the several definitions.
Jesus, you want the general public to be informed, but you make a point of trying to look WAY more intelligent than you are and attacking people who call you out on it.
If the public never "gets it", it's precisely because people acting like you.
You care more about looking smart than educating people.
This seems over the top. People here have answered your question by giving links and explaining the question.
If it is confusing, it is because it is complex.
And people tend to forget that the words they use are not always in common usage or have specific meaning within the niche.
You have only been a member for a little over a week, the people here have been studying the climate for many years, are specialised in the topic and know what they are talking about. That is not being pretentious, they just forget sometimes that what they know is not common knowledge.
Google is your friend. Sometimes it takes effort to learn on your own part. Rather than lash out, thank the people for answering your question, keep asking more questions and be prepared for a learning curve.
The general public does not have time for this type of thing, which is understandable in some ways because it is complex, and many people dislike complexities because it requires effort to unfold them. It is also why the climate crisis will continue to be underestimated and will only be acted on when the brut force personally affects them.
It's not confusing because it's complex. It's not even confusing. Physics, except on the quantum level, isn't confusing even when it is complex, because it's purely logical and everything fits together neatly, even when it gets complicated because physics on the macro scale fundamentally makes sense if you have a technical background. Unlike quantum physics nothing about it contradicts our experience.
Google is your friend is an obviously intentionally insulting statement.
Here's something else that is your friend:
When someone wants to learn, and asks, in so doing proving they don't know a lot about the subject, don't use jargon specific to that subject if you don't need to.
A person uses ONE WORD as if it explains something. I google it, and it's all about geology, and oh, my mistake, I should have known I had to include high pressure or meteorology as an additional keyword. Except no. There is nothing obvious about that.
Except the thing is, if I ask what's so bad about high pressure, if you apparently know so much about meteorology, you should infer quite easily that subsidence will mean even less to me than high pressure as high pressure is a term obviously more commonly used in basically every context than subsidence. That makes it quite absurd to claim the use of that word is in any way helpful to anyone that doesn't know what makes high pressure bad.
I work with mechanical engineers every day, I got a degree in aerospace engineering. We don't deal with heat transfer or HVAC often, but heat transfer has come up. The word subsidence has never come up between engineers, and we're pretty nerdy.
