Can a cloud do that? Actually, pictured above are several clouds [ http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/cld/cldtyp/home.rxml ] all stacked up into one striking lenticular cloud [ http://sa1.star.uclan.ac.uk/~prn/lenticular/clouds.html ]. Normally, air moves much more horizontally [ http://en.wikipedia.org/wiki/Jet_stream ] than it does vertically. Sometimes, however, such as when wind comes off of a mountain [ http://antwrp.gsfc.nasa.gov/apod/ap020723.html ] or a hill [ http://antwrp.gsfc.nasa.gov/apod/ap030416.html ], relatively strong vertical oscillations take place as the air stabilizes. The dry air at the top of an oscillation [ http://snrs.unl.edu/amet351/noehrenberg/lenticularclouds.html ] may be quite stratified [ http://antwrp.gsfc.nasa.gov/apod/ap030430.html ] in moisture content, and hence forms clouds [ http://www.stemnet.nf.ca/CITE/cloudsform.htm ] at each layer where the air saturates with moisture. The result can be a lenticular cloud [ http://antwrp.gsfc.nasa.gov/apod/ap030326.html ] with a strongly layered appearance. The above picture was taken near Mauna Kea [ http://volcano.und.nodak.edu/vwdocs/volc_images/north_america/hawaii/mauna_kea. html ], Hawaii [ http://en.wikipedia.org/wiki/Hawaii ], USA [ http://www.cia.gov/cia/publications/factbook/geos/us.html ].
