Description:
This sunrise picture is punctuated by the Contrails of several Eastbound airplanes which Left San Francisco International Airport 20 or so minutes earlier. Contrail formation is dependent on various factors such as temperature, humidity, etc. These factors are not necessarily constant throughout the sky - there may be 'patches' or layers of sky where the temperature is lower or higher, for example. One patch of sky may contain the conditions that allow contrail formation, while another, just a few miles ahead, might not. An aircraft passing through these patches might leave a contrail while in the first one, which would then appear to 'turn-off' as it passed into the second. An aircraft travelling through a number of these patches will leave a contrail that appears broken in places. Alternatively, a contrail may begin as unbroken, but different weather conditions along the contrail may cause the contrail to disperse more quickly in certain places while not in others, again leaving a broken contrail effect.
