摘要

本研究分析了从纽约州、新泽西州和康涅狄格州的 44 个气象站收集的日气温和降水量数据,以评估和量化这些州的历史气候变化。该研究对空间和时间趋势进行了详细分析,重点关注最能代表各地区气候多样性的特定站点。一个关键的分析方面是比较城市和郊区的气温趋势,主要侧重于纽约市。研究结果表明,所有季节的平均气温都呈显著上升趋势,其中市区,尤其是纽约市,上升最为明显。这一趋势在春季尤为明显,反映出气候变化的影响在不断升级。研究还发现,年平均气温上升的同时,气温范围的变化也在减小,这表明随着时间的推移,气温波动趋于稳定。此外,我们还发现热浪频率明显增加,城市地区比郊区更为明显。对降水模式的分析,尤其是对纽约市降水模式的分析表明,降雪日数有所减少,这与总体变暖趋势一致。研究结果表明,季节平均气温呈显著上升趋势,气温变化幅度减小,热浪发生率上升,而城市地区通常会经历更温暖的条件。这项综合研究强调了对空间降水趋势进行更深入分析的必要性。它强调了继续开展研究以了解气候变化的多方面影响的重要性,特别是在区分城市和农村的影响方面。

Historical Climate Trends and Extreme Weather Events in the Tri-State Area: A Detailed Analysis of Urban and Suburban Differences
This study analyzes daily temperature and precipitation data collected from 44 weather stations throughout New York, New Jersey, and Connecticut to assess and quantify the historical climatic changes within these states. The study conducts a detailed examination of spatial and temporal trends, focusing on specific stations that best represent the climatic diversity of each area. A critical analysis aspect involves comparing temperature trends in urban and suburban areas, mainly focusing on New York City. The findings reveal a significant upward increasing trend in average temperatures across all seasons, with urban areas, especially NYC, exhibiting the most marked increases. This trend is notably sharp in the spring, reflecting climate change’s escalating influence. The study also observes an increase in the annual average temperatures and a concurrent decrease in the variability of temperature ranges, suggesting a stabilization of temperature fluctuations over time. Also, we identified a notable increase in heat wave frequency, more so in urban locales than in their suburban counterparts. Analysis of precipitation patterns, particularly in NYC, reveals a decline in snowfall days, consistent with the general warming trend. The results demonstrate significant trends in seasonal average temperatures, a decrease in the variability of temperatures, and a rise in heat wave occurrences, with urban areas typically experiencing warmer conditions. This comprehensive study highlights the need for a more in-depth analysis of spatial precipitation trends. It underscores the importance of continued research in understanding the multifaceted impacts of climate change, particularly in differentiating urban and rural experiences.
