摘要

Abstract >At subannual timescales, terrestrial water storage (TWS) plays a critical role in the partitioning of precipitation into runoff and evapotranspiration, and Amazonia stands out due to the great amplitude of the annual cycles. In this study, we analyse the monthly variation of the water balance and extreme hydrological events using GRACE data for a watershed situated in the “arc‐of‐deforestation” in the Eastern Brazilian Legal Amazon. The existence of a correlation and lag time response between the monthly sea surface temperatures in the Pacific and North Atlantic and the variables of the water balance were also investigated. The results showed a weak seasonal cycle of evapotranspiration, with higher water intercepted by the vegetation canopy in the rainy season and higher potential evapotranspiration supplied by TWS in the dry season. The lowest value of water storage was reached in December 2015 during the strongest El Ni?o event observed in the analysed period (2002–2016). This value impacted the streamflow for at least the entire rainy season. The correlation analysis showed that positive anomalies of the Ni?o 3.4 index from October to March caused a significant decrease in precipitation in the following March to May and in November, a significant increase in the reference evapotranspiration in April and May, and longer lasting effects on the streamflow and TWS. Although the underlying mechanisms contributing to the time delays remain incompletely understood, the results indicate that consideration of the ENSO influence on the water balance and of the TWS influence on streamflow would improve flood and drought forecasts with benefits for water management. </abstract> </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 Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >在亚地金属尺寸下，陆地储水（TWS）在降水分配到径流和蒸散的分区中起着关键作用，并且由于年周期的巨大幅度振幅，亚马逊乏力。在这项研究中，我们分析了在巴西的“陆战法”法律亚马逊的“陆战陆战队弧形”中的流域水平和极端水文事件的月度变化。还研究了太平洋和北大西洋的每月海面温度与水平衡变量之间的相关和滞后时间响应。结果表明，蒸散季节性季节性循环较弱，雨季植被冠层截取的较高水分，在干燥季节中提供的潜在蒸散率较高。在分析期间（2002-2016）中观察到的最强的EL NI o活动期间，2015年12月达到了最低价值。这一值影响了至少整个雨季的流流。相关分析表明，10月至3月份的NI 3.4指数的正面异常在3月至11月举行的降水量显着下降，4月份参考蒸散量显着增加，持久效果更长在Streamflow和TWS上。虽然有助于时间延误的潜在机制仍然不完全理解，但结果表明，思考enso对水平和TWS对流流量的影响的影响将改善洪水和干旱预测水管理的益处。</ p> </摘要> </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>2020年第6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=Cavalcante Rosane B.
