Question

at what approximate altitude would clouds begin to form when the surface air temperature is 30 and the dew point is 14

Answer 1

Well, a normal environmental lapse rate is 6°C per 1000m, so it should be simple proportion.

The temperature needs to drop by 16°, so:

16/6 × 1000 = 2,666.66

So the answer is APPROXIMATELY 2700m (Assuming that the surface is at 0m)

Hope this helps!
