The complex behaviors of the<br \/>\n_\/ solar-terrestrial environment, e.g., the phenomena of solar flares and<br \/>\n_\/ geomagnetic storms, are an indication that it is in a state<br \/>\n_\/ far-from-equilibrium whereby instabilities, nonlinear waves, and<br \/>\n_\/ turbulence play key roles in the system dynamics. One of the<br \/>\n_\/ ubiquitous features of the solar-terrestrial environment is the<br \/>\n_\/ occurrence of intermittency and chaos in the solar dynamo, solar<br \/>\n_\/ corona, solar wind, and terrestrial<br \/>\n_\/ magnetosphere-ionosphere-atmosphere. The characterization of the<br \/>\n_\/ chaotic and intermittent nature of the sun-Earth system is essential<br \/>\n_\/ for efficient monitoring and forecasting of space weather and space<br \/>\n_\/ climate, as well as global climate change. In this talk, we show that<br \/>\n_\/ the dynamical systems approach is capable of elucidating the origin of<br \/>\n_\/ the intermittent dynamics in the solar-terrestrial environment. Two<br \/>\n_\/ partial differential equations are considered: the<br \/>\n_\/ Kuramoto-Sivashinsky equation and the regularized long-wave equation,<br \/>\n_\/ which govern the nonlinear evolution of Alfven waves and drift waves<br \/>\n_\/ in plasmas, respectively. We demonstrate that a chaotic attractor in<br \/>\n_\/ space plasmas and fluids is composed of chaotic saddles and unstable<br \/>\n_\/ periodic orbits, and explain the links between theses unstable<br \/>\n_\/ structures and spatiotemporal intermittency.<br \/>\n_\/<br \/>\n_\/ Chian, A.C.-L. et al., JGR 111, A07S03, 2006.<br \/>\n_\/ Rempel, E.L. and Chian, A.C.-L., PRE 71, 016203, 2005.<br \/>\n_\/ He, K. and Chian A.C-L., PRE 69,026207, 2004.<br \/>\n_\/ He, K. and Chian, A.C.-L., PRL 91, 034102, 2003.<br \/>\n_\/ Chian, A.C.-L. et al., PRE 65, 035203(R), 2002.<br \/>\n_\/<br \/>\n_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/<\/p>\n<p>\u4e16\u8a71\u4eba\uff1a\u5c71\u7530 \u9053\u592b(\u4eac\u5927\u6570\u7814)\u3001\u85e4 \u5b9a\u7fa9(\u4eac\u5927\u7406)\u3001\u677e\u672c \u525b(\u4eac\u5927\u7406)\u3001<br \/>\n\u30a2\u30c9\u30d0\u30a4\u30b6\u30fc\uff1a\u85e4\u5742\u535a\u4e00\uff08\u4eac\u5927\u60c5\u5831\u5b66\uff09\u3001\u8239\u8d8a \u6e80\u660e\uff08\u4eac\u5927\u60c5\u5831\u5b66\uff09\u3001<br \/>\n\u6c34\u5cf6 \u4e8c\u90ce(\u540c\u5fd7\u793e\u5927\u5de5)\u3001\u4f59\u7530 \u6210\u7537\uff08\u4eac\u5927\u7406\uff09<br \/>\n\u9023\u7d61\u5148\uff1ayamada@kurims.kyoto-u.ac.jp<br \/>\n\u30e1\u30fc\u30eb\u30ea\u30b9\u30c8\u9023\u7d61\u5148\uff1a semi-adm@kyoryu.scphys.kyoto-u.ac.jp<\/p>\n<p>\u623b\u308b [http:\/\/www.kyoryu.scphys.kyoto-u.ac.jp\/semi\/semi2.html]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/_\/ _\/ _\/ \u6d41\u4f53\u529b\u5b66\u30bb\u30df\u30ca\u30fc \uff12\uff10\uff10\uff16 No. \uff19 _\/ _\/ [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16,26],"tags":[],"class_list":["post-426","post","type-post","status-publish","format-standard","hentry","category-16","category-26"],"_links":{"self":[{"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts\/426","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=426"}],"version-history":[{"count":0,"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts\/426\/revisions"}],"wp:attachment":[{"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=426"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=426"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=426"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
