1-What relationship exists between the wind at 3000 feet and the surface wind?

050 4069 Wind

The surface wind is veered compared to the wind at 3000 feet and is usually weaker. They are practically the same, except when eddies exist, caused by obstacles The wind at 3000 feet is parallel to the isohypses and the surface wind direction is across the isobars toward the low pressure and the surface wind is weaker. They have the same direction, but the surface wind is weaker, caused by friction

There will be a sudden temporary increase in true air speed. None, since wind only affects ground speed and drift. There will only be a gradual increase in true airspeed until equilibrium is established again. There will be a sudden temporary decrease in true air speed.
