“October’s bright blue weather”
“O suns and skies and clouds of June,
And flowers of June together,
Ye cannot rival for one hour October’s bright blue weather;”
Helen Hunt Jackson (1830-1885)
October Skies Not so Blue.
Airplane clouds instead of blue.
Clouds that hide the hue.
Days not so blue and bright.
Clouds and water vapor warm the night.
Water vapor that jets exude,
Winter cooling of the arctic preclude.*1
A six month warmer arctic night,
Bring polar bears a serious plight.
Days are not so bright and blue,
All year long jets dim the hue.
On 9/13 a with cooler night,
The day time sky was again very bright.*2
On many a night,
The stars are not so bright.
The daytime hue,
Is not very blue.
When the skies you watch,
Computer models do not match.
More looking needed
Less computation heeded.
*1: Water vapor has the most greenhouse effect
Much stronger than carbon dioxide. Water vapor
is effective over most of the infrared radiation,
heat, spectrum; it does not need to be visible as clouds.
Carbon dioxide is only effective over a narrow part of this heat spectrum.
Water vapor, humidity, is much more prevalent; typically 30%, dry to 80%, high/
Carbon dioxide is only about 0.4%.
*2: When air traffic was stopped after 9/11
for a few days the days were brighter and warmer,
the nights were clearer and cooler.
