    Default Thats not virga...

    A bit of a knit pick but I am almost positive that todays comment picture ,entitled "can you see the virga," is not actually a picture of virga but of genuine rain shafts.
    The clouds at ground level clearly demonstrate that the column of air through which the rain droplets are falling is mostly at saturation. Thus it is all but impossible for the rain droplets to be evaporating on their descent, which is the definition of virga.

    True, the air just above these low clouds is not at 100% saturation, but I'd put money on the fact that these rain drops are making it to the ground.

    I'll shut up now.
