摘要

Abstract >Temporal and spatial variations of the midlatitude ionospheric trough during a geomagnetic storm on 4 April 2017 have been investigated using Global Navigation Satellite System total electron content data together with Arase satellite observations. After the geomagnetic storm commencement, the trough minimum location moves equatorward from 60 to 48° in geomagnetic latitude within 4?hr. The trough minimum location identified from the Global Navigation Satellite System total electron content data is located near the footprint of an abrupt drop of electron density detected by the Arase High‐Frequency Analyzer instrument. The longitudinal variation of the trough minimum location shows a significant variation with a scale of 1,000–2,500?km during both storm and quiet times. This phenomenon has not yet been reported by previous studies. After the onset of the storm recovery phase, the trough minimum location rapidly moves poleward back to the quiet time location within 4?hr. </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> > 2017年4月4日在地磁风暴期间的中间电离层槽的时间和空间变化使用全球导航卫星系统进行全部电子含量数据与ARASE卫星观测一起调查。在地磁风暴开始后，槽的最小位置在4？小时内在地磁纬度下赤道60至48°移动。从全局导航卫星系统识别的槽最小位置总电子含量数据位于ARASE高频分析仪检测到的电子密度突然下降的占地面积附近。槽最小位置的纵向变化显示出在风暴和安静的时间内为1,000-2,500Ωkm的显着变化。以前的研究尚未报道这种现象。在暴风雨恢复阶段开始后，槽的最小位置快速移动回到4？小时内的安静时间位置。</ 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-23539/'>《Geophysical Research Letters》</a> <b style="margin: 0 2px;">|</b><span>2018年第15期</span><b style="margin: 0 2px;">|</b><span>共9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=Shinbori Atsuki&option=202" target="_blank" rel="nofollow">Shinbori Atsuki;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Otsuka Yuichi&option=202" target="_blank" rel="nofollow">Otsuka Yuichi;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Tsugawa Takuya&option=202" target="_blank" rel="nofollow">Tsugawa Takuya;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Nishioka Michi&option=202" target="_blank" rel="nofollow">Nishioka Michi;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Kumamoto Atsushi&option=202" target="_blank" rel="nofollow">Kumamoto Atsushi;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Tsuchiya Fuminori&option=202" target="_blank" rel="nofollow">Tsuchiya Fuminori;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Matsuda Shoya&option=202" target="_blank" rel="nofollow">Matsuda Shoya;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Kasahara Yoshiya&option=202" target="_blank" rel="nofollow">Kasahara Yoshiya;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Matsuoka Ayako&option=202" target="_blank" rel="nofollow">Matsuoka Ayako;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ruohoniemi J.
