values around 37 °C (Fig. 14.5), with differences among different parts of the city
being maximal about 2 °C. PET values (Fig. 14.6) on that day reached over 46 °C
in the city centre, with difference through the city being a bit higher compared to the
differences in the air temperatures. Values of PET over 40 °C started already around
9 in the morning and continued to 5 in the afternoon. Especially in the evening, the
differences between city centre and periphery exceeded 8 °C.
