2. According to the dissertation "THERMAL FIELD AND URBAN HEAT ISLANDS ESTUDY IN SANTA MARIA-RS", by Alexandre Pistoia Saydelles, the greatest diversification in thermal responses detected concerned the topoclimate, due to the natural and urban factors, also to the Sun position during the imaging time, which have defined four distinct thermal situations. Analysing the field experiments, due to the “North Wind” action in the dissipation of the thermal responses, there was no significant formation of “Urban Heat Islands” (UHI). Although, under summarized Polar Domain conditions, the city registered UHI formation of high magnitude. It was possible to assert that the imposition of regional atmospheric systems acts directly in the definition of the thermal field and in the UHI formation, therefore being considered to effectuate a better urban planning and a greater understanding of the local climatic variants. Note: these studies are preliminary and yet inconclusive. UHI effects reasons: Center: Highly densified, more use of heat absorbing material (concrete) Rural: Less densification, more vegetation, presence of water, dirt roads 3. I would propose investments in qualification open terrains with green and blue infrastructure, especially on high UHI formation areas. 4. I am not aware of any structured policies reggarding UHI effect.
