How come plane A...leaves a normal looking trail...and yet plane B leaves a trail, MILES long...that forms into clouds?
When you look at clouds in the sky, do you not see that they are present at different altitudes? The air is not all the same, everywhere, at all
altitudes. Temperature, relative humidity and thus water vapor saturation levels are different, and constantly changing over time.
Your "plane A" and "plane B" are at different altitudes.....it is that simple.
How do these trails turn a blue day, into a cloudy one?
Same way any clouds form and then develop. The contrails will act as a "trigger", when they form in conditions that allow even MORE clouds. The
clouds will appear eventually, it is the nature of the ever-changing weather in the Earth's atmosphere. Contrails do act to speed up the process,
And also, please do tell me, is CLOUD SEEDING a reality??? If so, is WEATHER MODIFICATION, a
Of course, there are plenty of places where "cloud seeding" is discussed. Haven't you read them? It would help if you would, so at least would have
the understanding of what it means, to "seed" clouds. You see, the only reason for that is to make precipitation happen. To kick Nature in the butt,
to spur it along.
You have to have a cloud, though...in the first place, to have something to "seed". AND, not just any cloud either.
Contrails are cirrus clouds.....they look like cirrus, behave like cirrus, and evolve like cirrus. And cirrus clouds do NOT make rain or snow, and
are of course NOT "seeded" in order to attempt to make precipitation.
Now, sorry, but this is off-topic and a bit inane, but I include it only as an indicator of the sort of illogical "comparisons" that are commonplace
in so many flawed "arguments" of this sort:
Sure, libraries have books with pictures....but 100 years from now, when someone opens a history book, from today....will they believe fire
melts steels....causing 100 story buildings to fall, at freefall speed; defying gravity and the laws of physics? Why do i use that as an example?
Well, because HIS-story can be changed, whenever "they" deem necessary. How do you KNOW those books weren't reprinted...and redistributed? Now, call
me "silly" but IS IT POSSIBLE????
Nothing in that rant has any hint of truth to it, just repeats of the same fallacies, with a bit of absurd thrown in.....to actually "ask" if old
copyrighted books in libraries have been "reprinted
Come on....this is so ridiculous, I'd be embarrassed for even suggesting it.
