According to<br \/>\nLorenz, predictability is limited by the upscale cascade of errors<br \/>\nbeginning at the smallest scales that are not subject to viscous<br \/>\ndissipation.  Thus, the flapping of a butterfly&#8217;s wings might be<br \/>\nsupposed to change the weather on a relatively short time scale.<\/p>\n<p>Nevertheless, numerical weather prediction has been reasonably<br \/>\nsuccessful without accounting for the behavior of butterflies.  We will<br \/>\nreview the various modifications to the notion of atmospheric<br \/>\npredictability that have been proposed since Lorenz&#8217;s paper and present<br \/>\nnew results from recent ensemble simulations of strong winter storms.<br \/>\nWe will show that after a few modifications, Lorenz&#8217;s model is able to<br \/>\ndo a surprisingly good job of describing the loss of predictability in<br \/>\nthe ensemble forecasts.  In the process, we will see why butterflies<br \/>\nare of no practical importance.<\/p>\n<p>+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;+&#8211;<\/p>\n<p>\u4e16\u8a71\u4eba\uff1a\u5c71\u7530 \u9053\u592b(\u4eac\u5927\u6570\u7406\u7814)\uff0c \u85e4 \u5b9a\u7fa9(\u4eac\u5927)\uff0c\u677e\u672c \u525b(\u4eac\u5927\u7406)<br \/>\n\u30a2\u30c9\u30d0\u30a4\u30b6\u30fc\uff1a\u8239\u8d8a \u6e80\u660e\uff08\u4eac\u5927\u60c5\u5831\u5b66\uff09\u3001\u6c34\u5cf6 \u4e8c\u90ce(\u540c\u5fd7\u793e\u5927\u5de5)\u3001<br \/>\n          \u4f59\u7530 \u6210\u7537\uff08\u4eac\u5927\u7406\uff09<br \/>\n\u9023\u7d61\u5148\uff1a\u5c71\u7530\u9053\u592b yamada__at__kurims.kyoto-u.ac.jp<br \/>\n=========================================================<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u6d41\u4f53\u529b\u5b66\u30bb\u30df\u30ca\u30fc\u6d41\u4f53\u529b\u5b66\u30bb\u30df\u30ca\u30fc \u6d41\u4f53\u529b\u5b66\u30bb\u30df\u30ca\u30fc\u306e\u304a\u77e5\u3089\u305b\u3067\u3059\uff0e \u65e5\u6642\u3068\u5834\u6240\u304c\u901a\u5e38\u3068\u5927\u304d\u304f\u7570\u306a\u308a\u307e\u3059\u306e\u3067\u3054\u6ce8\u610f\u304f\u3060\u3055\u3044\uff0e ================================================ [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16,19],"tags":[],"class_list":["post-293","post","type-post","status-publish","format-standard","hentry","category-16","category-19"],"_links":{"self":[{"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts\/293","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=293"}],"version-history":[{"count":0,"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=\/wp\/v2\/posts\/293\/revisions"}],"wp:attachment":[{"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=293"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=293"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/kyoryu.scphys.kyoto-u.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=293"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
