Climate change is exacerbating the risk of the occurrence of extreme weather. This study has projected the change in mean and extreme climate conditions in Central Poland during near-future (2026-2050), mid-term (2051-2075), and far-future (2076-2100) periods under two climate-change scenarios in six General Circulation Models (GCMs) from Coupled Model Intercomparison Project Phase 6 (CMIP6). The results showed that, compared to the historical reference period (1990-2014), Central Poland will experience an increase in temperature and precipitation by the end of the twenty-first century. It is expected that the mean annual temperature and mean annual precipitation totals will increase by 1-4.8 °C and 2-7.5%, respectively. Furthermore, it is projected that the average number of hot, very hot days and extremely hot days (Tmax > 25 °C, > 30 °C, and > 35 °C), tropical nights (Tmin > 20 °C), and extremely high daily precipitation (> 10 mm, > 20 mm and > 30 mm) will also increase, while the average number of slight frost days (Tmin < 0 °C), and frost and severe frost days (Tmax < 0 °C, Tmax < - 10 °C) will decline on average by the end of the twenty-first century. Therefore, it is essential for policymakers to take some appropriate measurements and strategies in advance to strengthen resilience to extreme climate events.
气候变化正在加剧极端天气发生的风险。本研究预测了波兰中部在近期(2026 - 2050年)、中期(2051 - 2075年)和远期(2076 - 2100年)期间,在耦合模式比较计划第6阶段(CMIP6)的六个全球气候模式(GCMs)下两种气候变化情景中的平均和极端气候条件变化。结果表明,与历史参考期(1990 - 2014年)相比,到21世纪末波兰中部气温和降水量将增加。预计年平均气温和年平均降水总量将分别增加1 - 4.8℃和2 - 7.5%。此外,预计炎热、非常炎热和极其炎热的天数(最高气温>25℃、>30℃和>35℃)、热带夜晚(最低气温>20℃)以及极高日降水量(>10毫米、>20毫米和>30毫米)的平均数量也将增加,而轻微霜冻天数(最低气温<0℃)以及霜冻和严重霜冻天数(最高气温<0℃、最高气温<-10℃)到21世纪末平均将减少。因此,政策制定者提前采取一些适当的措施和策略以增强对极端气候事件的适应能力至关重要。
