Sorry to burst your bubble, Al Roker.....
What you got there are pictures of normal, everyday contrails.
Jets flying overhead, at high altitudes make 'em.
Not every day, of course...but on some days it's just too dry up there. Plenty of days when it's overcast (low clouds, stratus and cumulus) then
you would (if able to rise above the overcast) likely see the contrails then, too.
BUT YOU DON'T, because of the lower cloud cover. SO on the occasional nice, clear day, selective memory kicks in, and this "chemtrail" nonsense
Now, before you get started on "But, it's hot, dry and 80 degrees where I am!" type of argument, I suggest you go learn mor about our earth's
atmosphere, and its make up, especially high altitude characteristics.
This is knonw as "meteorology", and there are some darn good books on the topic, and even some good sites online, too...
If you want to get into it more, and come to understand the airplanes that are making the contrails, there's a site (since you're in the USA) that
offers LIVE, real-time flight tracking:
You said Southern California (a place I know VERY well, born and raised there), Pasadena in particular....so, at the FlightAware site enter the proper
airport code for LAX...it requires the ICAO four-digit code "KLAX".
(I already did that, to get you started)...
Any nearby airport will do (eg, KONT, KSNA, etc) also. The map just centers on it, when input.
The airplane icons shown in green are the ones just passing by...and the ones in blue are arriving/departing the selected airport. The altiudes (last
two zeroes dropped off) are shown in the data blocks, second line, first numbers. Second set of numbers on that line show the groundspeed, in
An interesting flight I just noticed....is offshore about four miles, when I looked...its data block is:
AAL 774 B738
(It will have moved, by now...I am just describing it, for the moment, because it's interesting).
BECAUSE....this flight has departed Las Vegas, destination LAX....YET it is at 24,000 feet, westbound offshore! G/S is 164 knots. It is an American
Airlines flight 774, a Boeing 737-800.
I can only surmise it is having some sort of inflight difficulty, that's the only reason to explain its location and altitude, given what little I
know from the data block info.
Perhaps it will be on the evening news out there!
Fact that a LOT of airplanes pass overhead, in the airspace above you, isn't a big surprise. VERY busy area for air traffic.
Update: Well, might have been a glitch in the flightaware software...because I tracked AAL 774's progress, and it has landed safely, after a typical
40-minute flight from LAS. Still, anomalies like that get my attention!
