J.R. Hott, seorang pilot helikopter telah berjaya mengambil gambar menarik ini di sepanjang pantai di Panama City, Florida. Berikut adalah komen meteorologist tentang fenomena ini.
"Cool air offshore was very nearly at the saturation
point, with a temperature near 20ºC and a dew point of about 19.5ºC. The
air at this temperature can only hold a certain amount of water vapour,
and how much it can hold depends heavily on the temperature. If you add
more water into the air, a cloud will form, but you can also get a
cloud to form by cooling the air. Drop the temperature, and it can no
long hold as much water vapour, so some of it will condense out and a
cloud will form. In this case, the air was cooled by lifting it
about 50 meters over the top of the condos. A parcel of unsaturated air
will cool when lifted at a rate of 1ºC per 100 meters. In this case, it
probably cooled about 0.5 degrees C, but that was all it took! On the
back side of the condos, the air slowly sinks back down and warms at the
same rate. As it warms the air can hold more water vapour and the cloud
evaporates and disappears!"
