Snowing NIMBOSTRATUS (LOW) Photo taken by Lin Chambers at NASA Langley on February 27, 2002 during a late-season snow. Note the extremely uniform and featureless nimbostratus cloud which is dropping snow on the ground. Nimbostratus clouds are very difficult to photograph, because they are very uniform and offer little contrast. Generally nimbostratus clouds form rain, but snow is somewhat more photogenic.
Fractus clouds (scuds): small, ragged cloud fragments usually found under an ambient nimbostratus cloud base; drift rapidly with the wind; rain evaporates and mixes with the air, which becomes saturated and a lower layer of clouds or fog may form beneath the original clouds base (scud)
