The website Severe Weather Europe\u00a0<a href=\"http:\/\/www.severe-weather.eu\/mcd\/new-round-of-torrential-rainfall-for-parts-of-greece-in-the-next-48-hours\/\">warned early Thursday<\/a>\u00a0that 48-hour rainfall amounts of 200-400 mm (8 \u2013 16\u201d) were possible in parts of central and northern Greece.<\/p>\n<p>Non sapevo come si forma un uragano mediterraneo (Mediterranean hurricane, abbreviato in &#8220;medicane&#8221;) e la differenza con gli uragani oceanici. La stagione va da settembre a marzo, nonostante la temperatura alla superficie del mare sia bassa (attualmente 20 \u00b0C):<\/p>\n<p style=\"padding-left: 30px\">Since the waters of the Mediterranean aren\u2019t warm enough to support conventional hurricane development, medicanes rely on colder air aloft, typically brought in as part of an upper-level low that decays over the Mediterranean. Wind shear relaxes as the upper low decays, and the contrast between the cold air aloft and the relatively warm sea surface temperatures can stimulate the formation of showers and thunderstorms. These, in turn, may congeal around a weak surface low and help give it a symmetric, warm-core structure&#8211;and sometimes even a cloud-free, eye-like feature. Often a medicane\u2019s warm core will be enveloped within broader cold-core features, which makes it more akin to a hybrid or subtropical storm than a tropical storm.<\/p>\n<p>Prima di fine secolo i medicani dovrebbero essere rarissimi secondo un modello climatico regionale, ma \u00e8 basato su pochi dati &#8211; d&#8217;altronde la definizione \u00e8 ambigua e si censiscono da poco.<\/p>\n<p style=\"text-align: center\">*<\/p>\n<p><span style=\"color: #000000\"><strong><span style=\"color: #0000ff\"><a href=\"https:\/\/andthentheresphysics.wordpress.com\/2017\/11\/16\/a-real-time-global-warming-index\/\" target=\"_blank\" rel=\"noopener\"><span style=\"color: #0000ff\">Da aTTP<\/span><\/a><\/span><\/strong>,\u00a0Karsten Haustein\u00a0di Oxford spiega il <span style=\"color: #0000ff\"><a href=\"https:\/\/www.nature.com\/articles\/s41598-017-14828-5.pdf\" target=\"_blank\" rel=\"noopener\"><span style=\"color: #0000ff\">paper uscito<\/span><\/a><\/span> su <em>Scientific Reports<\/em>:<\/span><\/p>\n<p style=\"padding-left: 30px\"><span style=\"color: #000000\">We estimate human-induced warming over 1951\u20132010 to be +0.63\u00b10.08\u00b0C (105% of the total warming) in HadCRUT4, in line with the 2013 IPCC assessment (given to 1 decimal place) of +0.7\u00b10.1 \u00b0C based on more comprehensive attribution studies using the CMIP5 ensemble.
