Pre-Flight
This is a weather question. Yesterday, doing a dusk out night return from Oakland to O88 (Rio Vista where the fuel is cheap) it was smooth at 3,500 heading East, with a strong headwind. On the descent into the delta airport next to an ever growing windfarm, the air was rough and turbulent all the way to the surface.
Experienced the same on climb out, then smooth from 3,000' all the way up to 4,500'. Turning the nose of the Cessna to KOAK, picked up a lot of speed, at least 25 knots.
Is this considered an inversion, or wind shear?
Back at Oakland did my night currency pattern work, and it was quite calm and dark before moonrise.
