Abstract

Urban planning, through urban design and land use allocation, affects urban climate dynamics and patterns at different vertical layers of the urban boundary layer and spatial multiscale. Climate-sensitive urban planning and design draws attention to the consideration of climate parameters and their explanatory factors as a relevant element in decision-making. Local climate zones, defined from urban design variables such as building density and building height, allow for the recognition of homogeneous units useful for directing planning actions that allow cities and their population to adapt their climate behavior.This research compares the meso-scale climatic characteristics of the local climate zones proposed by Stewart and Oke for Chilean large cities located on an extensive latitudinal gradient (roughly 18 degrees S to 45 degrees S), on the coast of Chile and inland. In particular, the relationship between the behavior of surface temperature and vegetation is evaluated through the average Normalized Difference Vegetation Index (NDVI) for the decade (2008-2018). The results account for differences in the behavior of surface temperatures between climatic zones. In turn, vegetation is inversely related to the surface temperature, making it possible to distinguish the differences inside the LCZ, it being warmer in areas where the NDVI is lower.
