In spite of the global weather prediction implications, this is another beautiful land-sky-space scape to wake up to. The explanation is interesting reading as usual... even more poetic today for some reason.

I so enjoy my morning APOD's, especially these close-in earth views.

Anyone have more to add regarding the cloud migrations? Art, any alignment with your former work?

I was more concerned with ozone eating
wintertime polar stratospheric clouds (PSCs)

than with the (4 times higher)
summertime polar mesospheric clouds (PMCs).

But so far as tropical tropospheric clouds are concerned :
they do migrate north this time of year,
much like birds, (especially in India):

I remember when we had to pull trichlorethyline out of service in the PCB industry. I expect you were part of the catalyst in that regard. Now we are working towards lead-free. Seems the better something works (or tastes in the case of food) the worse it is for us and the environment

Did you primarily work with satellites or balloons? I expect the nacreous clouds were difficult to capture.

Maybe we will get an APOD of these nacreous clouds some day. 8) Or better yet, they become more and more rare!
