Is there a rule of thumb about the wind strength and direction above ground level and at different times of the day and night? I`ve just been reading the Confuser Manual and I`m a little lost, The metar says for example surface wind 05005kt during the night in summer, at 2000ft the answer would be A:12030kt B:09010kt C:12010kt D:09020kt. The answer is D. Another one: about 1400Z under clear skies, the wind is 22025kt, what would it be at 2000ft? A:26040kt B:24035kt C:22020kt D:23030kt. Answer is B, it says 25* wind and 50% increase in velocity along the isobars because it`s day time with solar energy
