Indicated Airspeed Lift Wind Shear 
Air Facts

The eddies mixing with the vertical motion of the heat generating lift of the heated air makes for discomfort. The up motion of the lift vector from the surface temperatures, and the perpendicular wind vectors pushing the heated air along, make for a dynamism in space. I looked at the airspeed and it was jumping +/-5-10 knots.

Wind Shear: The Abrupt Shift Wind shear refers to any abrupt divergence in wind characteristics be it speed, direction, or both that unfolds over a minimal distance. Can cause sudden losses or gains in indicated airspeed (IAS), directly affecting lift. And it’s unique in Europe!

Moderate wind shear in some areas could make some thermals somewhat difficult to work but that, too, is typical. There were some patches of moderate lift and sink as would be expected on a normal summer soaring day. ” Unlike tornadoes and other twisters, microbursts are straight-line winds. to 2 miles) in diameter.
