Cirrus and cirrostratus clouds are above this jet and its contrail. The over-exposed sun is actually about the size of the blue internal lens flare. There is no contrail shadow because the aircraft is below the clouds.

The contrails of the jets flying from CA eastward created the clouds this morning

Brown Acres - Jackson County - Oregon - USA

I have seen this turbulent effect a few times but this is the most graphic example. Pockets of winds aloft are rising and falling resulting in a twisted appearance as the contrail spreads.

sometimes one is just lucky. Lookup and an Airplane, perfect combination.

Had a bit of a dilemma when I looked at this -- photo taken mid-September, a lovely early fall morning in Bethesda. As is often the case, I was taken by the building and the contrails and took the photo -- then didn't process it until now. The dilemma was that it also made a great B&W shot. So, in the interest of my total indecision, I am posting them both here.

Not many 9 departures on hot summer days, so I stuck around to get a contrail or two. I got decently lucky because this guy departed long.

Not a bad sunrise. As long as you don’t mind contrails in your sky.

Contrails over Rijeka

Reddish Egret (egretta rufescens) ~ Sarasota County, Florida

 

The reddish egret possesses the ability to change direction and the kind of quickness that would make your average NFL running back insecure. In this instance, the bird had spotted some movement beneath the surface and had exploded from a dead stop. The 'contrails' of water droplets chart the path.

Contrails are line-shaped clouds produced by aircraft engine exhaust or changes in air pressure, typically at aircraft cruising altitudes several miles above the Earth’s surface. Contrails are composed primarily of water, in the form of ice crystals. The combination of water vapor in aircraft engine exhaust and the low ambient temperatures that exist at high altitudes allows the formation of the trails. (Source: Wikipedia)

Aircraft condensation trails (contrails) that have persisted for at least 10 minutes will be given the name of the genus, Cirrus, followed only by the special cloud name “homogenitus”, so a contrail will be known only as Cirrus homogenitus. As new, or recently formed aircraft condensation trails may undergo a fairly rapid state of change and may display a variety of transient shapes, no species, varieties or supplementary features will be applied to the name.

Exhaust contrails are formed by the mixing of the hot humid exhaust of the engines with cold humid surrounding air, creating long streamers of clouds. If the conditions are right then these can persist and spread. These are the most common type of contrail observed.
