Using monthly air temperature data from, 3202 meteorological stations for the period 1971-1990, the temperature zones of the world are redefined according to the Köppen (1884) thermal zone classification. Moreover, using monthly air temperature data from 155 stations from 1961 to 2020, the spatial changes in temperature zones are analyzed according to the reference climate periods 1961-2020, 1961-1990, 1981-2010 and 1990-2020. The world temperature map based on meteorological measurements is largely similar to Köppen’s map of 1884, which was prepared by utilizing various phytogeographic studies. The most obvious difference occurs in the polar belt in the Northern Hemisphere, which is not as widely distributed as in the 1884 map. However, some shifts in the boundaries of the so-called temperature belts were observed over Cape Horn, Madagascar island, southwest Australia and the Mediterranean Basin. On a larger scale, over Türkiye, the warm areas tended to shift further north and towards higher elevations, whereas the cold areas representing northeastern Anatolia shrank in area and the temperature regime changed. The results of this study reveal for the first time the spatio-temporal variation of the so-called Köppen (1884) temperature belts based on station data both in the world and in Türkiye. The results are useful for understanding the temperature characteristics on Earth and in Türkiye.
