Document Summary

Boundary layers = region above a surface where the flow is significantly influenced by the surface"s energy and mass exchange and surface friction. Atmospheric boundary layer = 300-3000m within troposphere, controlled by thermal mixing, and moisture and pollutants from the ground surface. Small scale dynamics = microscale weather ie. small-scale turbulence (short-term) > temperature variation, humidity, wind and air pollutants. Domain vs. resolution: (include specific phenomena/processes and exclude some others) Domain: wide large scale area that encloses a lot of atmostpheric processes, ie. all the macroscale models can be observed, assume model boundary conditions. Resolution: a certain area within the domain that can be parameterized, ie. applying laws or equations that can be represented on a more accurate scale, ie processes: clouds, effects on soil, etc. 3 types of energy and mass transfer: radiative change (electromagnetic, photons), molecular exchange (conduction and diffusion), turbulent exchange (convection) Flux density : if delta q (qin qout) is positive -> flux density convergence.
