AbstractThe Köppen method, the Worldwide Bioclimatic Classification System (WBCS), and Feddema's descriptive climate classification method are used to analyse the Larger Carpathian Region (LCR) climate. Minimum, maximum and average temperature, precipitation and latitude and elevation data as input data are taken from the CarpatClim dataset. It refers to the period 1961–2010 with a 1‐day temporal resolution and a spatial resolution of 0.1° × 0.1°. The methods are compared in terms of their capability to represent climate heterogeneity and thermal and moisture characteristics on the annual and seasonal time scales. The region's climate is analysed separately for lowland, hill, mountain and high mountain regions using the results of the Köppen method as reference. The WBCS gave the highest spatial climate heterogeneity, followed by Feddema's method, and then the Köppen method in all three region types. However, the WBCS has the largest data input requirement. The rarest climate type according to the Köppen method is ET. This climate type is registered according to the Feddema and WBCS methods by three different climate types. The most frequent climate type according to the Köppen method is Cfb. This climate type is represented by 19 and 14 climate types according to the Feddema and the WBCS methods, respectively. The most frequent climate type according to Feddema's method is cool and dry with extreme seasonality of T and according to WBCS it is temperate continental steppic supratemperate sub‐humid. The coldest climate is produced by Feddema, the warmest by the WBCS. The Feddema method treats seasonality in the most comprehensive way. The Feddema and the WBCS methods reproduced the large climate heterogeneity of the LCR. The results can also be used as basic information in the PannEx project, as well as in future environmental and regional climate change‐related investigations for estimating thermal and moisture stresses.
