Ifunyanwa eNew York, iqela leGeekosystem belizibuza ukuba kutheni le nto ubusika akubonakali kubusika kakhulu. Kukhithike kube kanye kuphela kwisiXeko saseNew York ukuza kuthi ga ngoku kulo nyaka, ngexesha elingaqhelekanga ngasekupheleni kuka-Okthobha, xa kuthelekiswa neli xesha lonyaka ophelileyo xa ngekhephu lalikwimimandla engama-49. Okwangoku, ziidigri ezingama-45 ngaphandle kwisiXeko saseNew York phakathi kuJanuwari, ezinokuphakama kwama-52. Oko akubandi kakhulu xa ucinga ngokwenzeka eNew Jersey kwisithuba esingaphezulu konyaka omnye odlulileyo. Kunyaka ophelileyo ngeli xesha, ikhephu elaligqunywe ngama-50% kwilizwe liphela, xa kuthelekiswa nemilinganiselo ye-19% ngoku. Kutheni kungabandi kangaka kulo nyaka? Isimo sezulu seWunderground UJeff Masters icacisa inento yokwenza nayo umlambo wejethi ongaqhelekanga kwezi nyanga zidlulileyo.
Umjelo obeka imozulu eMntla Melika ulawulwa yi-Arctic Oscillation kunye neNorth Atlantic Oscillation, eziyimodeli yemozulu emele uxinzelelo lwenqanaba lolwandle. Uxinzelelo olurekhodwe kuzo zombini ii-Oscillation lube lukhulu kakhulu, kunye neNyakatho yeAtlantic Oscillation ebeka owona mahluko mkhulu owakhe wabhalwa ngoDisemba, ngelixa iAtlantic Oscillation irekhode owesibini umahluko okhoyo. Ngenxa yomahluko woxinzelelo, umoya ofudumeleyo ovela emzantsi-ntshona uye wawela iMpuma ye-U.S. , ngokuchasene nomoya obandayo odla ngokutsalwa kwi-Arctic.
Ukuba uyazibuza ukuba kutheni, ngokuchanekileyo, amanqanaba arekhodiweyo kwi-North Atlantic Oscillation kunye ne-Arctic Oscillation aye agqithise kakhulu kulo nyaka, ngelishwa, iiMasters azinampendulo. Ucacisa esithi, iimodeli zemozulu ngokubanzi azikho lula ukwenza uqikelelo lobuchule malunga nokuba utshintsho olwenzeka kubuntu lungayichaphazela njani i-AO [iArctic Oscillation], okanye into enokwenzeka kwi-AO kwixesha elizayo. I-Masters iyaqaphela, nangona kunjalo, ukuba kukho unxibelelwano phakathi kwamabala elanga kunye namaxabiso aqinisekileyo kwii-Oscillations, naphakathi kokulahleka komkhenkce wolwandle lwearctic kunye namaxabiso amabi, nangona kungekho nanye kwezi zinto echaza ngokuthe ngqo ukuba kutheni singakhange sifumane ikhephu ngeKrisimesi, kwaye kutheni Sisanxibe iiteki ngaphandle endaweni yeebhutsi ezinkulu zekhephu zerabha.
