What is the temperature and dew point at sea level, east of the Alps in the following circumstance?

A moist westerly wind blows over the Alps 8000’ high. On the west coast at sea level the temperature is 18°c and the cloud base 4000’ AMSL. Precipitation takes place in the west and a cloud base at 7000’ forms on the eastern side of the ranges

• TT = 19ºC / DP = 1ºC

• TT = 18ºC / DP = 6ºC

• TT = 22ºC / DP = 0ºC

• TT = 22ºC / DP = 1.5ºC
