Question

1) Using numbers to show surface energy balance, and give explanation to each term you show

2) Calculate Bowen ration

3) Calculate the ration of sensible heat flux to absorbed surface insolation,

4) Calculate the ratio of latent heat flux to absorbed surface insolation

5) Compare (c ) and (d), which is larger and why?

incoming solar A radiation: 100% 340 W/m2 reflected solar radiation: emitted by atmosphere: 50% reflected by clouds & atmosphere: 23% atmospheric window: 12% absorbed in atmosphere: 23% Convection evaporation surface 25% radiation: reflected by absorbed by 117% surface: 73 surface 48 outgoing heat radiation: 71% mitted by clouds: 9% back radiation: 100%

Explanation / Answer

1)Here the surface radiation is 117% that is the heat liberated again from the surface to the upper atmosphere.

2)Bowen ratio is generally used to calculate the heat loss (or gained) in a substance.Here the Bowen ratio is given as .48(48/100) as 48%is absorbed by the land.
