How do trees and other vegetation affect urban mesoclimates and microclimates?
Vegetation affects urban mesoclimate and microclimate by intercepting solar radiation, directing air movement, and affecting air temperature. Microclimate, mesoclimate and macroclimate can be used to describe the climate of a given location. Macroclimate covers hundreds of square miles and parameters …
Uses of Urban Vegetation to Moderate Climate
Climatology is the study of weather and its changes over long periods of time. The climate within a given location can be described from three aspects: macroclimate, mesoclimate, and microclimate. Macroclimate, mesoclimate and microclimate can be used to describe the …
