First Phase
1. As Surface temperature increase its increase the evaporation (+ve feedback)
2. As evaporation increase its decrease the surface temperature (-ve feedback)
3. As evaporation increase, water vapour in the atmosphere also increase ( +ve feedback)
4. With increase in water vapour in atmosphere, surface temperature also increase. (+ve feedback)
Second Phase
5. Water vapour increase, relative humidity also increase (+ve feedback)
6. Relative humidity lead to increase cloud cover (+ve feedback)
7. But due to condensation increase in cloud cover reduce water content in the atmosphere (-ve feedback)
8. Surface temperature decrease with increase in relative humidity (-ve feedback)
Third Phase
9. Greater cloud cover mean low radiation (-ve feedback)
10. Also greater cloud cover leads to low incoming solar radiation (-ve feedback)
11. High radiation means high surface temperature(+ve feedback)
12. But high outgoing radiation reduce surface temperature (-ve feedback)
13. On the other hand high incoming radiation increase surface temperature (+ve feedback)
