    Notes: Abstract  The physiological equivalent temperature, PET, is a thermal index derived from the human energy balance. It is well suited to the evaluation of the thermal component of different climates. As well as having a detailed physiological basis, PET is preferable to other thermal indexes like the predicted mean vote because of its unit (°C), which makes results more comprehensible to urban or regional planners, for example, who are not so familiar with modern human-biometeorological terminology. PET results can be presented graphically or as bioclimatic maps. Graphs mostly display the temporal behaviour of PET, whereas spatial distribution is specified in bioclimatic maps. In this article, some applications of PET are discussed. They relate to the evaluation of the urban heat island in cities in both temperate climates and warm climates at high altitude. The thermal component of the microclimate in the trunk space of a deciduous forest is also evaluated by PET. As an example of the spatial distribution of PET, a bioclimatic map for Greece in July (Mediterranean climate) is presented.

    Analysis of Energy Balance Components as a Function of Orography and Land Use and Comparison of Results with the Distribution of Variables Influencing Local Climate (1999)

    Notes: Summary During 1992 and 1995 in the Upper Rhine valley between Karlsruhe in the north and Basel in the south 36 energy balance stations were installed to analyze the spatial and temporal behavior of the components of the energy balance. A second aim of the project ‘Regio-Klima-Projekt’ (REKLIP) was to study the dependence of climatic variables on the energy balance. Three main influences on spatial variation in energy balance components were detected: orography, precipitation and land use. Concerning the dependence of the climatic variables on the energy balance it can be stated that the mean diurnal amplitude of temperature shows a good correlation with the mean diurnal sensible heat flux, while the diurnal amplitude of the specific humidity correlates with the mean diurnal latent heat flux. Both these results are in good agreement with theoretical considerations. Consequently, areas with enhanced sensible heat flux values show higher monthly mean temperature maxima and also a greater numbers of summer days, while areas with higher latent heat flux values indicate enhanced monthly mean humidity maxima.
