Suured vulkaanipursked v\u00f5ivad m\u00f5jutada ilmastikku ja on inimkonna ajaloos toonud seel\u00e4bi m\u00f5nikord kaasa ka p\u00f5uda, \u00fcleujutusi, ikaldust ja n\u00e4ljah\u00e4da. N\u00fc\u00fcd selgub, et v\u00e4hemalt Hiina ajaloos on vulkaanide roll olnud suurem kui seni arvatud.<\/p>\n

V\u00e4rske teadusuuring, mis vaatles enam kui nelja sajandi kohta leitud andmeid, on vulkaanipursete ja toidupuuduse seosed Hiinas senisest selgemini esile toonud.<\/p>\n

Richard Warren \u0160veitsist Berni \u00dclikoolist ja ta kolleegid anal\u00fc\u00fcsisid aastaist 1440 kuni 1900 p\u00e4rit \u00fcrikuis talletatud teavet.<\/p>\n

Nad tuvastasid, et vulkaanipurskeile j\u00e4rgnenud muutusi \u00f5hutemperatuuris ja sademete hulgas tuli ette j\u00e4rjekindla reeglip\u00e4rasusega.<\/p>\n

<\/p>\n

Vulkaanipurskel paiskub k\u00f5rgele atmosf\u00e4\u00e4ri v\u00e4\u00e4vlit sisaldavaid gaase. Need soodustavad aerosooliosakeste teket, mis hakkavad p\u00e4ikesevalgust tagasi kosmosse peegeldama. Nii alaneb \u00f5hutemperaruur ja muutub sademere\u017eiim, m\u00f5nikord isegi mitmeks aastaks.<\/p>\n

Suurte pursete j\u00e4rgseid ilmastikumuutusi on t\u00e4heldatud \u00fcle maailma. Hiina ei ole erand. Seniseis teadust\u00f6is on aga valdavalt k\u00e4sitletud \u00fcksikjuhtumeid, Warren ja ta kolleegid annavad n\u00fc\u00fcd s\u00fcstemaatilise \u00fclevaate.<\/p>\n

Nad kirjutavad ajakirjas Climate of the Past<\/a>, et seosed maailma vulkaanide aktiivsuse ja Hiinas ette tulnud p\u00f5udade, \u00fcleujutuste ja ikaldustega on statistiliselt olulised. Seega, suure t\u00f5en\u00e4osusega mitte juhuslikud.<\/p>\n

Kuid Hiina eri piirkonnis on seosed olnud siiski isesugused.<\/p>\n

P\u00f5hja-Hiinas on ilmastik vulkaanipurskeile reageerinud k\u00f5ige kiiremini. Seal on n\u00e4ljah\u00e4da tihti saabunud juba purskega samal aastal.<\/p>\n

Mujal Hiinas on m\u00f5ju olnud keerukam ja avaldunud aeglasemalt. Kesk-Hiinas on n\u00e4lg tulnud tihtilugu alles kuni kolme aasta jooksul p\u00e4rast purset. L\u00f5una-Hiinas taas on k\u00f5ige n\u00e4ljaohtlikum olnud purske aastale j\u00e4rgnenud aasta.<\/p>\n

Teadlaste s\u00f5nul tuleks n\u00fc\u00fcd edasi anal\u00fc\u00fcsida, millest need erinevused on tulnud. P\u00f5hjuseks v\u00f5ivad olla nii ilmakujunemise regionaalsed erip\u00e4rad, p\u00f5llumajandustavad v\u00f5i toidujaotuss\u00fcsteemid, mis k\u00f5ik v\u00f5ivad omal moel m\u00e4\u00e4rata, kuidas loodusj\u00f5udude raev \u00fchiskonnaelus v\u00e4ljendub.<\/p>\n
