| Term | Definition |
|---|---|
| Transmission | The passage of shortwave and longwave energy through either the atmosphere or water. |
| Scattering | Deflection and redirection of isolation by atmospheric gases, dust, ice,and water |
| Refraction | The transition subjects in insolation to a change of speed, which also shifts its direction in bending action |
| Reflection | The portion of arriving insolation that is returned directly to space without performing any work |
| Albedo | The reflective quality of a surface expressed as the percentage of reflected insolation to incoming insolation; A function of surface, color, angle of incidence and surface texture. |
| Cloud Albedo Focusing | An increase in albedo caused by clouds |
| Cloud Greenhouse forcing | An increase in greenhouse warming caused by clouds |
| Global Diming | The decline in sunlight reaching the earths surface due to population |
| Conduction | The molecule-to-molecule transfer of heat energy as it diffuses through a substance. |
| Convection | The physical mixing involves a strong vertical motion |
| Advection | when horizontal motion dominates in the physical mixing |
| Greenhouse effect | The rough similarity between the process and way a greenhouse operates |
| Jet contrails | Produce high cirrus clouds stimulated by aircraft exhaust |
| Microclimatology | the science of physical conditions at or near earths surface |
| Net radiation | The balance of all radiation at earths surface |
| Urban Heat island | both max and minimum temperatures higher than those of near by rurel settings |
| Dust dome | Air borne population, which can be blown from the city in elongated plumes |
| Transparency | water is clear and light passes through it to an average depth of 60 m in the ocean |
| Gulf Stream | moves northward off the east coast of North America carrying warm water far into the north America |
| Specific Heat | The heat compacity of a substance |
