GOES-8 Visible Satellite Loop
DISSIPATION TRAILS (a.k.a. Distrails)
Aircraft evaporation trails originally made through clouds in the western (left) part of the area move rapidly eastward and expand due to dispersion, as the cloud mass is bodily advected (blown) eastward in the air flow. Note how little distortion of the trails occurs; they remain nearly straight. This indicates a remarkably uniform flow field at the level where the distrails were created -- a homogeneity which is unusual across over 100 miles of an air mass.
