    摘要:長(cháng)江中下游受季風(fēng)氣候和全球變暖影響強烈,高溫熱浪、干旱、洪澇等氣象災害頻發(fā),制作該地區熱浪和干旱指標數據集對于開(kāi)展氣候變化下極端事件監測和氣象災害風(fēng)險評估具有重要的科學(xué)意義。本數據集基于長(cháng)江中下游地區1961—2020年逐日氣溫和降水觀(guān)測資料,經(jīng)數據篩選、質(zhì)量檢測和異常值剔除,采用熱浪指數和連續無(wú)有效降水日數作為判別標準,計算每個(gè)站點(diǎn)熱浪和干旱的日數、頻次及最長(cháng)持續時(shí)間三個(gè)指標,并分時(shí)段、分省份對各個(gè)指標數據值進(jìn)行整理統計,得到長(cháng)江中下游地區熱浪和干旱指標數據集。經(jīng)時(shí)空一致性檢驗以及與已有文獻資料對比驗證,結果表明本數據集可信程度高,可為分析長(cháng)江中下游地區不同時(shí)空范圍的熱浪和干旱變化特征提供數據支撐,也可作為基礎數據進(jìn)一步研究熱浪和干旱事件對氣候變化的響應及其對農牧業(yè)生產(chǎn)和人類(lèi)生活的影響。

    Abstract & Keywords
    Abstract:?The Yangtze River basin, particularly its middle and lower reaches, is significantly influenced by the monsoon climate and the pervasive effects of global warming. This region frequently endures meteorological calamities such as high temperatures, heatwaves, droughts, and floods. The compilation of heatwave and drought index datasets holds substantial scientific value for the monitoring of extreme weather events and the assessment of risks associated with meteorological disasters amidst climate change. Utilizing daily temperature and precipitation observation data from 1961 to 2020 across the Yangtze River, a meticulous process of data screening, quality assurance, and outlier removal was conducted. This rigorous methodology ensured the collection and establishment of a dataset that delineates the indices and durations of heatwaves and droughts in the region. The dataset was subsequently subjected to temporal and consistency tests and was corroborated against existing literature.The findings affirm the dataset's high reliability, providing robust support for the analysis of long-term heatwave and drought characteristics along the Yangtze River. Moreover, this dataset serves as foundational data for further investigation into the responses of heatwave and drought events to climate change, as well as their implications for agricultural productivity and human well-being.
    Keywords:?Heat wave index;?Drought index;?Multiple spatiotemporal scales;?Meteorological Station;?The middle and lower reaches of the Yangtze River
