The aim of this paper is to understand the role of the macrocirculation factor in shaping the dynamics of long-term bioclimatic conditions, with reference to Kłodzko in the Polish part of the Central Sudetes. The variability of bioclimatic conditions in Kłodzko for the period 1966–2017 was analysed, exposing its local specificity. The Universal Thermal Climate Index (UTCI) was taken as an indicator of the analysed bioclimatic features. The influence of the North Atlantic Oscillation (NAO) on the variability of this index and its constituent meteorological elements, e.g. air temperature, vapour pressure, wind speed, and solar conditions, was examined. On the basis of the winter NAO Hurrell coefficient, the analysed years were divided into two opposing groups representing either a negative or positive Hurrell index. A comparison between these two year-groups for the mean values of UTCI and the examined meteorological elements showed a clear intergroup difference in these values. Except for cloudiness, the importance of the macrocirculation genesis of NAO was verified by the statistically significant correlation between the Hurrell index on the one hand and the tested UTCI index and its constituent meteorological elements on the other.

本文的目的是参考中南部苏打山脉波兰地区的Kodzko，了解宏观循环因子在塑造长期生物气候条件动态方面的作用。分析了1966年至2017年期间科沃兹科的生物气候条件的变化，揭示了其局部特异性。通用热气候指数（UTCI）被用作分析生物气候特征的指标。考察了北大西洋涛动（NAO）对该指数及其组成气象要素（如气温，蒸气压，风速和日照条件）的变化的影响。根据冬季NAO Hurrell系数，将分析年份分为两个相对的组，分别代表负或正的Hurrell指数。这两个年份组的UTCI平均值和所检查的气象要素之间的比较显示，这些值之间存在明显的组间差异。除了浑浊之外，一方面通过Hurrell指数与被测UTCI指数及其组成的气象要素之间的统计学显着相关性，证明了NAO的大循环发生的重要性。
