Pic Today 11/3/12





PINK CONTRAILS
IN A MORNING SKY

Jet aircraft were painting pink paths
across an early morning sky,
as the sun's first rays cast a
red glow on these thin straight clouds.

For these aren't true clouds,
but "contrails" (a contraction
for "condensation trails.")

It takes a very cold upper atmosphere
to form these exhaust streaks from aircraft,
which are actually water ice crystals from
the combustion of hydrogen rich fuel and oxygen.

Contrails start straight and thin,
but soon broaden and dissipate.

(Brush strokes telling us
winter is on the way.)
