Physics Help Forum Heat transfer in atmosphere

 Jan 5th 2017, 11:51 AM #1 Junior Member   Join Date: Jan 2017 Posts: 12 Heat transfer in atmosphere A cirrus uncinus cloud (a hook-like cloud appearing at an altitude between 5 to 15 km and indicating a slowly approaching storm) has an average thickness L 1000m . The extinction coefficient for the cloud is 3 -1 2.2 10 m     e . The intensity of the irradiation at the top of the cloud is 2 , qr A  830 W/m Determine the time variation of the length-averaged cloud temperature. Neglect the heat transfer by surface convection and the energy conversion due to phase change, i.e. the air is in equilibrium with the cloud. Assume that the volume- averaged density and specific heat of the cloud are 3   0.8 kg/m and  2000 J/(kg K) p c . Assume that the surface reflectivity of the cloud is zero.

If you can type the equations out using LaTeX that would be very helpful. Enclose your equation in [math ] and [/math] tags.
