della distanza dall'osservatore, può manifestarsi come un colpo secco e forte oppure come un rombo basso e prolungato.<br /> Il fulmine causa un forte aumento di pressione e temperatura che a sua volta provoca la rapida espansione del canale ionizzato prodotto dal fulmine stesso: l'espansione dell'aria produce infine un'<a href="/wiki/Onda_d%27urto" title="Onda d&#39;urto">onda d'urto</a> che si manifesta con il rumore del tuono. In prossimità del canale ionizzato, i tuoni producono sempre rumori molto forti. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Cause_del_tuono">Cause del tuono</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Tuono&amp;veaction=edit&amp;section=1" title="Modifica la sezione Cause del tuono" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Tuono&amp;action=edit&amp;section=1" title="Edit section&#039;s source code: Cause del tuono"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>La prima teoria sulle cause del tuono di cui si abbia traccia è attribuita al filosofo greco <a href="/wiki/Aristotele" title="Aristotele">Aristotele</a> nel <a href="/wiki/III_secolo_a.C." title="III secolo a.C.">III secolo a.C.</a>: una primitiva speculazione lo faceva derivare dalla collisione delle nuvole.<br /> Si susseguirono molte altre teorie tra cui quella di metà del <a href="/wiki/XIX_secolo" title="XIX secolo">XIX secolo</a> con la quale si riteneva che il fulmine producesse il <a href="/wiki/Vuoto_(fisica)" title="Vuoto (fisica)">vuoto</a>. </p><p>Nel XX secolo si affermò l'ipotesi che il tuono fosse causato dall'enorme spostamento d'aria provocato dal <a href="/wiki/Fulmine" title="Fulmine">fulmine</a> nell'<a href="/wiki/Atmosfera" title="Atmosfera">atmosfera</a> a seguito della improvvisa espansione termica del plasma nel canale ionizzato.
