SUN Lab scientist explained how particular hot spots in a city form an urban heat island

SUN lab researcher Mikhail Varentsov in collaboration with Russian and German colleagues explained the patterns of temperature rise in megacities. Scientists from RUDN University, Moscow State University, Moscow Center for Fundamental and Applied Mathematics with colleagues from Ruhr University in Bochum (Germany), Freiburg University (Germany) and Berlin Technical University (Germany) found that not only the alternation of local climatic zones, as previously thought, but also the heterogeneity of the urban environment on a scale of several kilometres make a significant contribution to the formation of an urban heat island on the scale of the entire city. This can be compared to the synergy effect, when the result of the interaction of several factors is more powerful than the sum of the effects caused by the same factors separately.
