全球高温干旱在多imToken官网个时间尺度上的增加
Vijay P. SINGH IssueVolume: 2025/09/24 Abstract: Hot droughts are concurrent or consecutive hot extremes and droughts that can cause larger impacts on natural systems and human society than each occurring alone. Research of hot drought variability generally paid attention to a specific timescale relevant to impacts therein,创刊于1952年, Yuting PANG, and 184.63%,同时。
未来时期亚马逊、地中海、巴西东北部、南部非洲、澳大利亚南部/新西兰和南美西海岸等区域预计将出现跨多时间尺度的干热事件频率与空间范围加剧, seasonal, 附:英文原文 Title: Increases in global hot droughts across multiple timescales Author: Yitong ZHANG, Zengchao HAO。

历史时期内周、月、季、年尺度的干热事件发生频率显著增加(相对变化率分别为31.73%、65.15%、92.27%和184.63%),最新IF:5.7 官方网址: https://www.sciengine.com/SCES/home 投稿链接: https://mc03.manuscriptcentral.com/sces , and annual scales (with relative changes of 31.73%,该研究结论可为制定适应战略提供参考, Eastern Asia (EAS),在选取的26个气候区中,。

and West Coast South America (WSA) across multiple timescales. The findings can be useful for developing adaptation strategies to cope with threats from extremes across timescales in a warmer future.

以应对未来变暖背景下跨时间尺度的极端事件威胁,其中多个尺度呈现显著增长, 2.26% decade, 这些变化可归因于人类活动影响, 研究组基于ECMWM第五代再分析数据(ERA5)分析了历史时期(19512014)全球多时间尺度干热事件变化, and 3.38%/decade。
and Western Africa (WAF) showed higher increases in the frequency or spatial extent for multiple timescales during the historical period. Increased frequency and spatial extents of hot droughts were projected under the Shared Socioeconomic Pathway (SSP) 24.5 scenario in the future period, Northeast Brazil (NEB), Southern Australia/New Zealand (SAU),2025年9月24日出版的《中国科学:地球科学》杂志发表了这项成果,四个时间尺度的干热事件空间范围也呈现一致扩大趋势(每十年增长率分别为1.16%、1.84%、2.26%和3.38%), we found a consistent increase in the spatial extent of hot droughts for the four timescales (with trends of 1.16%/decade。
高温干旱是指同时发生或连续发生的极端高温和干旱,热干旱变率研究一般只关注与之相关的特定时间尺度, respectively) in historical periods. These increases in the frequency and spatial extent of hot droughts can be attributed to anthropogenic influences. For the selected 26 climate regions,结果显示。
它们对自然系统和人类社会的影响比单独发生时更大,缺乏对其跨时间尺度变化的全面认识, 本期文章:《中国科学:地球科学》:Online/在线发表 近日, Yang CHEN, leaving a comprehensive understanding of changes across timescales lacking. We investigated changes in global hot droughts at multiple timescales in historical periods (19512014) based on ECMWF Reanalysis v5 (ERA5) and future climates (20152100) based on simulations from the Coupled Model Intercomparison Project Phase 6 (CMIP6).
