摘要

本文分析了1961年至2020年波兰热季节的变化。根据55个站点的月平均气温值,计算了六个热季的开始和结束日期以及持续时间。考虑到每年0°C、5°C和15°C的热阈值,可以区分早春、春季、夏季、秋季、初冬和冬季。波兰热季的开始日期和持续时间存在显著的空间差异。大陆主义(在东部)和海洋气候(在西部)的影响以及波罗的海的影响是显著的,在山区,海拔高度是主要因素。波兰的气温以0.3°C–0.4°C/10的速度上升 年。这导致热季节的发生和持续时间发生重大变化。观察到早春和早春的早期开始。夏天来得更早,时间更长,成为一年中最长的季节(超过110 在波兰南部的日子)。秋天和初冬推迟了,时间变短了,而冬天来的要晚得多。全国各地的冬天是44 白天更短,而在西北部,这种情况根本没有发生。热季节开始的变化是全球变暖进程的一个明确指标。它们对环境和人类活动也有决定性的影响。

Variability in the occurrence of thermal seasons in Poland in 1961–2020

Variability in the occurrence of thermal seasons in Poland in 1961–2020

The article analyses the variability of thermal seasons in Poland in 1961–2020. Based on the average monthly air temperature values from 55 stations, the onset and end dates as well as the duration of the six thermal seasons were calculated. Taking into account the thermal thresholds of 0°C, 5°C and 15°C for each year, early spring, spring, summer, autumn, early winter and winter can be distinguished. A significant spatial differentiation of the dates of the beginning and duration of the thermal seasons in Poland was observed. The influence of continentalism (in the east) and oceanic climate (in the west) and the influence of the Baltic Sea are noticeable, and in mountainous regions, altitude above sea level is the main factor. The air temperature in Poland increases at the rate of 0.3°C–0.4°C/10 years. This causes significant changes in the occurrence and duration of the thermal seasons. An early beginning of early spring and spring was observed. Summer arrives earlier and is significantly longer, becoming the longest season of the year (above 110 days in the south of Poland). Autumn and early winter are delayed and get shorter, whereas winter comes much later. Throughout the country, winter is 44 days shorter, and in the north-west it does not occur at all. Changes in the onset of thermal seasons are a clear indicator of progressing global warming. They have also a decisive impact on the environment and human activity.
