Spatio‐temporal pattern of meteorological droughts and its possible linkage with climate variability

摘要

ABSTRACT >Spatial pattern of meteorological droughts is a critical element for investigating drought condition. Empirical orthogonal function (EOF) and rotated EOF (REOF) methods are widely used to discriminate dominant patterns. Previous works focused on case applications but left the associated physical meanings unexplored. This study employs the EOF, wavelet analysis, and stepwise regression methods to distinguish spatio‐temporal patterns of meteorological droughts with pattern interpretation. For this purpose, monthly precipitation data were used from 73 meteorological stations in the Poyang Lake basin of China for the period of 1960–2007. Standardized Precipitation Index (SPI) was applied to quantify meteorological droughts. Our results identified four leading EOF/REOF patterns at the basin scale. Seasonal SPI series showed more dominant periods than monthly SPI series, indicating periodic complexity of regional droughts. The dominant periods coincided with those of the EOF/REOF time coefficients. The four leading EOF/REOFs were significantly related to the dominant time scales of 2, 3, 6, 11, 16, and 17 years, except for the fifth EOF/REOF. Stepwise regression analysis further indicated that the four leading EOF/REOFs be likely the superposition of SPI variation from inter‐annual and inter‐decadal scales. The SPI series at different time scales (1–36 months) showed significant correlations with climate teleconnection modes, confirming the existence of identified spatio‐temporal pattern. The Ni?o3.4 and Southern Oscillation were the primary teleconnection modes that influenced the variability of meteorological droughts over the basin. The Pacific Decadal Oscillation and the North Atlantic Oscillation also contributed to the regional dry/wet alternation. The findings provide important implications for understanding spatial and tempo </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <title type =“main”>抽象</ title> >空间模式气象干旱是调查干旱状况的关键要素。经验正交功能（EOF）和旋转的EOF（REOF）方法被广泛用于区分显性模式。以前的作品专注于案例应用程序，但留下了未探索的相关物理意义。本研究采用EOF，小波分析和逐步回归方法来区分气象干旱的时空模式与模式解释。为此目的，每月在1960 - 2007年中国鄱阳湖盆地的73个气象站中使用每月降水数据。将标准化的沉淀指数（SPI）应用于量化气象干旱。我们的结果确定了盆地规模的四种领先的EOF / REOF模式。季节性SPI系列显示出比每月SPI系列更大的主导时期，表明区域性干旱的周期性复杂性。主导时期与EOF / REOF时系数的主导时期恰逢其股。除了第五eof / Reof之外，四个领先的EOF /再纺与2,3,6,11,16和17年的主导时间尺度有关。逐步回归分析进一步表明，四个领先的EOF /再掺杂可能是来自年度年间和跨度间尺度的SPI变异的叠加。不同时间尺度（1-36个月）的SPI系列显示出与气候直拨连接模式的显着相关性，确认存在识别的时空模式。 NI？O3.4和南方振荡是主要的扎切模式，影响了盆地气象干旱变异性。太平洋横跨振荡和北大西洋振荡也有助于区域干/湿交替。调查结果为了解空间和节奏提供了重要的影响 </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-21026/'>《International Journal of Climatology: A Journal of the Royal Meteorological Society》</a> <b style="margin: 0 2px;">|</b><span>2018年第4期</span><b style="margin: 0 2px;">|</b><span>共15页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhou Han&option=202" target="_blank" rel="nofollow">Zhou Han;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Liu Yuanbo&option=202" target="_blank" rel="nofollow">Liu Yuanbo;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Key Laboratory of Watershed Geographic SciencesNanjing Institute of Geography and Limnology Chinese Academy of SciencesChina;</p> <p>Key Laboratory of Watershed Geographic SciencesNanjing Institute of Geography and Limnology Chinese Academy of SciencesChina;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1232.html" title="气候学">气候学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=meteorological drought&option=203" rel="nofollow">meteorological drought;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=spatial pattern&option=203" rel="nofollow">spatial pattern;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=climate teleconnection&option=203" rel="nofollow">climate teleconnection;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Standardized Precipitation Index&option=203" rel="nofollow">Standardized Precipitation Index;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=empirical orthogonal function&option=203" rel="nofollow">empirical orthogonal function;</a> </p> <div class="translation"> 机译：气象干旱;空间模式;气候拨连接;标准化降水指数;经验正交功能;
