Goose vee

Wheel to the storm and fly

Migrating south, a vee of Canada geese gets scattered by air turbulence as they take a right turn to head for safe waters 40 miles away.

Did you count them?

There are 93 Canada geese in that flight.  Not a lot, but more than usual.

Golden contrail

At cross angles to each other

The setting sun imparts a golden hue to the contrail of an airplane about to fly out of view.

Long and short of contrails

Atmospheric conditions cause airplane engines to form exhaust contrails.  These are caused by the hot and moist engine exhaust gases mixing with the cold air.   Long contrails mean the air at the flight level is very humid.  Short contrails indicate drier air and a lack of water vapor in the atmosphere at that altitude.  Very low relative humidity air will rarely produce a contrail.

Short trail

Long trail

In the two exemplars shown here, the contrails are produced by a four-jet engine airplane.

Sliding to the left

Seat shadows

The slanting sun casts seat slat shadows on the sidewalk.

Brick faces

Heavily pointed wall

Years of weather exposure and too diligent cleaning have worn down the faces of the bricks in this wall.
