Erdei, B.; Bruch, A. A.: A climate analysis of Late Oligocene (Egerian) macrofloras from Hungary

In the case of Vértesszőlős the wide range of values for MAT and CMT raises difficulties in comparing the relevant variables, though a bit cooler climate would be indicated by the minimum values for both variables (MAT =13.3 °C, even negative value for CMT = -0.1 °C). Values for both WMT and MAP are consistent for all localities. The resultant climate variables correspond to a Cfa-climate sensu KOPPEN (1931). MAT ranging between 15.6-18.8 °C in most cases (max. value 20.5 °C set by Ulmus carpinifolia in Eger 2 and Pomáz) conforms to that proposed by KVACEK and HABLY (1991) for the Eger-Wind flora (~ 15 °C). In Vértesszőlős the minimum limit of value set by Taxodium distichum at 13.3 °C designates somewhat cooler climate, however, the maximum limit of value is similarly high as for Andornaktálya MAT CMT WMT MAP Carpinus sp.
