Question 21
XE-HNAT2 marksNeeds review
Consider a layer of atmosphere between 5 and 6 km height. The downwelling longwave radiation at 5 and 6 km is 240 and 230 Wm⁻², respectively. The upwelling longwave radiation at these heights is 260 and 240 Wm⁻², respectively. The longwave heating rate in this layer is ____ K per day. (Round off to one decimal place.)
Take the average density of air in this layer to be 0.5 kg m⁻³; Specific heat capacity of air at constant pressure = 1000 J kg⁻¹ K⁻¹.
