Abstract

Klimatologi napovedujejo, da bodo v prihodnjih desetletjih vročinski valovi na Nizozemskem pogostejši. Ob upoštevanju tega dejstva sta avtorja v raziskavi merila mestno toploto in oblikovala model energijske bilance površja v Rotterdamu. Na podlagi geografskega informacijskega sistema (GIS), 3D-modelov in satelitskih posnetkov sta podrobno določila družbene, morfološke in prostorske vidike mesta ter z uporabo hierarhične in multivariatne regresijske analize opredelila povezave med temperaturami in energijsko bilanco površja ter družbenimi, morfološkimi in prostorskimi vidiki. Izsledki raziskave so pokazali povezavo med učinkom mestnega toplotnega otoka in zdravjem ljudi v Rotterdamu, poleg tega sta avtorja statistično pojasnila tudi izjemno visoko umrljivost ljudi, starih 75 let ali več, poleti 2006. Pomembno vlogo pri tem so imeli prostorska zgoščenost starejših prebivalcev, povprečna starost stavb, v katerih so živeli, ter skupni senzibilni in shranjeni toplotni tok. Vidiki, ki najbolje pojasnjujejo rotterdamski toplotni otok, so neprepustnost površja, indeks listne površine, stavbni ovoj, vodne površine in osenčenost. Avtorja sta jih predstavila na dveh t. i. temperaturnih kartah, na podlagi katerih se lahko določijo prednostne naloge pri izvajanju ukrepov prilagajanja podnebnim spremembam.

Secondary abstract:	Climate scientists forecast that heat waves will occur more often in the Netherlands in the coming decades. The Hotterdam study accordingly measured urban heat and modelled the surface energy balance in the Dutch city of Rotterdam. It identified in detail the city%s social, morphological, and land-use dimensions using a geographic information system% (GIS), 3D models, and satellite images. It used hierarchical and multivariate regression analyses to determine the links between temperatures and the surface energy balance on the one hand, and social, morphological, and land-use aspects on the other. The Hotterdam study did establish a link between the urban heat island effect in Rotterdam and the health of its population. It also statistically explained the high rate of mortality among seniors seventy-five and over during the summer of% 2006. The spatial concentration of senior citizens, the average age of the buildings they live in, and the sum of the sensible heat flux and storage heat flux play a large role. Imperviousness, the leaf area index, the building envelope, surface water, and shade are the dimensions that best explained the Rotterdam urban heat island. We mapped these aspects in two heat-maps that help in setting priorities for implementing climate adaptation measures.
