The dew point depression (Tdd) is defined as the difference between the temperature and dew point temperature at a given level: Tdd = T – Td. Using the expression given in lecture (slide 19 of lecture 4), plot on a graph the height of the LCL (Liding Condensation level) (y-axis; units of km) vs. the surface dew point depression (x-axis; units of ˚C). Do this for dew point depression values ranging from 0˚C to 15˚C. You may code this or do...
