Altostratus and cirrocumulus

Altocumulus and altostratus.

Stratocumulus and cirrostratus

16) During the climb after take-off, the altimeter setting is adjusted at the transition altitude. If the local QNH is 1023 hPa, what will happen to the altimeter reading during the resetting procedure ? Report

It will remain the same

It is not possible to give a definitive answer

It will decrease

17) What relationship exists between the wind at 3000 feet and the surface wind? Report

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

They are practically the same, except when eddies exist, caused by obstacles

Environmental lapse rate

Surface temperature

Dry adiabatic lapse rate

19) At the approach of a warm front (northern hemisphere) the wind direction changes from the surface up to the tropopause. The effect of this change is that the wind Report

veers in the friction layer and veers above the friction layer

backs in the friction layer and veers above the friction layer

veers in the friction layer and backs above the friction layer
