If you know the temperature (T) and dew point (Td) of an air parcel at the surface, you can calculate the LCL using the following equation. LCL=125m x (TTd).
Calculate the LCL:
Parcel A Parcel B
surface temperature 30 degrees C 30 degrees C
Surface dew point 20 degrees C 10 degrees C
________LCL __________LCL
Which parcel holds more water vapor at the surface?
What do the above calculations tell you about the relationship between dew point at surface temperature and the height of cloud base under humid as opposed to arid conditions?

LCL is the height where air has cooled to the dew point. We can calculate LCL using temperature and dew point at the surface. Like temperature dew point also decreases with height because of decreasing pressure. Ew point drops at the …
