In Chapter II, the microclimate of a level surface without vegetation was considered. Then in Chapters V and VI, this assumption was abandoned, and the interactions of vegetation and microclimate were studied. Now the assumption that the ground is level will also be abandoned, and the influences exerted on microclimate by the topographic variations of the terrain will be investigated. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
