摘要

Abstract >Heat waves (HWs) are one of the current topics of scientific research in the context of global warming, as they can have a disastrous impact on both environment and society. Therefore, detailed studies of variations of HWs that assess variability on spatiotemporal scales are becoming increasingly necessary. The main objective of this study is to detect and analyse variation in HWs and potential climate drivers across China based on K?ppen climate classifications. Daily observation data (maximum and minimum temperature) from 1961 to 2016 were used in the study to define HWs based on excess heat factors (EHFs). Linear trend analysis, Bayesian change‐point analysis, cross‐wavelet transform method, and Pearson correlation analysis method were adopted to identify the trends, variability and resonance periodicity of EHFs in sub‐regional, and the possible links between EHFs and large‐scale climate patterns, respectively. Results show that there was an overall significantly increasing trend of EHFs over six climatic zones except for HWM in the Polar tundra (ET). The spatiotemporal characteristics of EHFs in mainland China vary considerably. The spatial patterns of the mean annual EHFs are similar to their change trend. The spatial pattern of the number of individual HWs, the number of days that contribute to HWs, and the length of the longest HW in arid (BB), semi‐arid (BS) and cold semi‐humid (DW) areas of study is the west exceeding the east; temperate humid (CF) is contrary to that, with the south exceeding the north in temperate semi‐humid (CW) and ET. In addition, the mean temperature of all heatwaves (HWM) and the peak daily value in the hottest HW appeared in parts of northern DW, CF and BS. Change point first occurs in the northern and then in the southern region across mainland China, excepting HWM. A dominant positive correlation was found for Multivariate ENSO Index (MEI) and Arctic Oscillation Index (AOI) with EHFs, while a dominant negative correlation was detected for Pacific Decadal Oscillation (PDO) and the North Atlantic Oscillation (NAO) across China. A common significant 2–4 year periodical oscillation was detected in the EHFs series at the nationwide scale. Strengthening anti‐cyclone circulation in the Mongolian Plateau, and weakening monsoon flow and speed have contributed to the changes in EHFs across China. </abstract> </span> <span class="z_kbtn

>热浪（HWS）是全球变暖背景下的科学研究的当前主题之一，因为它们可能对环境和社会产生灾难性的影响。因此，对评估时尚尺度变异性的HW变化的详细研究变得越来越必要。本研究的主要目的是根据K？PPEN气候分类检测和分析中国跨越HWS和潜在气候司机的变化。从1961年至2016年的日常观察数据（最大和最低温度）用于研究基于过量的热因子（EHFS）来定义HWS。采用线性趋势分析，采用贝叶斯变化点分析，跨小波变换法和皮尔逊相关分析方法来确定次区域EHFS的趋势，变异性和共振周期，以及EHF和大规模气候之间的可能链接模式分别。结果表明，除了极地苔原（ET）中的HWM外，EHFS超过六个气候区的总体显着提高了趋势。中国大陆ehfs的时空特征大幅不同。平均年度EHF的空间模式类似于其变化趋势。单个HW的数量的空间模式，有助于HW的天数，以及干旱（BB），半干旱（BS）和冷半湿度（DW）研究的最长HW的长度西方超过东方;温带潮湿（CF）与此相反，南方超过北方的温带半湿润（CW）和ET。此外，所有热浪（HWM）的平均温度和最热门HW中的峰值日值出现在北部DW，CF和BS的部分。改变点首先发生在北方，然后在中国大陆的南部地区发生，除了HWM。对于具有EHF的多元ENSO指数（MEI）和北极振荡指数（AOI）发现了显性正相关，而在中国的太平洋横向振荡（PDO）和北大洋振荡（NAO）检测到显着的负相关。在全国范围内的EHFS系列中检测到常见的2-4年期定期振荡。加强蒙古高原的反旋风循环，弱化季风流动和速度对中国ehfs的变化有助于变化。</
