| dc.description.abstract | The movement and causes of this movement in Earths atmosphere depend merely on the magnitude and distribution of the net radiative heating of the earth atmosphere system. In the troposphere, the net adiabatic heating rate is dominated by the imbalance between the transfer of heat from the surface and the thermal emission of radiation to space. Latent heat is the major component of the flux from the surface to the atmosphere, and clouds play a major role in the emission of radiation to space. In the stratosphere the net heating depends solely on the imbalance between local absorption of solar UV radiation and infrared radiative loss. In this region, ozone is the principal absorber and carbon dioxide is the dominant emitter. Infrared emission by ozone and water vapor, molecular oxygen, carbon dioxide and nitrogen dioxide play a secondary roles. The distribution of the radiative sources and sinks due to the above gases exerts a zero order control on the large-scale seasonally varying mean temperature and zonal wind fields of the stratosphere. These radiative process are therefore, significant to understand the stratosphere- troposphere interactions. In generally, this study (project) introduces the basic principles of radiation, solar radiation and their process in the stratosphere and troposphere. | en_US |
