Dear Gary et al,
Density in the atmosphere is a function of pressure (which itself is a
function of altitude) so that if there were a lower density area (i.e.
lower pressure area) it would immediately be filled in by nearby higher
pressure regions. Indeed the effect you propose would require significant
differences in density-much great than those differences seen at sea level
in our normal weather patterns. I think what is being seen here cannot be
due to pressure differences.
Clear skies,
TR
