KOKOA
ʻO kahi hui o nā mea noiʻi mai ke Kulanui o New York ma Abu Dhabi, United Arab Emirates, ua hoʻolaha i ka lehulehu i ka loaʻa ʻana o kahi ʻano ʻano ʻē o nā nalu lā i ʻike ʻole ʻia ma mua. He mau nalu acoustic kēia, ʻike ʻia lākou i ka hoʻokumu ʻia ʻana o nā vortices nui ma ka ʻili o ka Lā, neʻe lākou ma ka ʻaoʻao ʻē aʻe i kona hoʻololi ʻana a, ʻoi loa enigmatic, neʻe lākou i nā manawa ʻoi aku ka wikiwiki ma mua o ka wānana maoli.
Ma kahi noiʻi hou i paʻi ʻia ma Nature Astronomy, ua ʻimi nā ʻepekema i nā ʻano hana hiki ke wehewehe i kēia mau nalu, akā ʻaʻohe o lākou i kūpono i ka ʻikepili i ʻike ʻia. ʻAʻole hiki i nā manaʻo i loaʻa ke hoʻoholo i ke kumu o
'swirls', he mea pohihihi keia mau mea. Hōʻike ka ʻike i ke ola ʻana o kahi lāʻau lapaʻau hou i ʻike ʻia.
Me kona mau hoa hana, ʻo Chris Hanson, ka mea kākau mua o ka haʻawina, e pili ana i ke ʻano he 'high frequency retrograde vorticity waves'. Ua hōʻike ʻia ka ʻikepili o ka ʻikepili mai nā makahiki he nui o ka nānā ʻana o ka lā i ka neʻe ʻana o nā nalu like a puni ka Lā ʻekolu manawa, no laila ʻaʻole hiki ke wehewehe ʻia kēia ʻano e nā ʻano hoʻohālike o ka neʻe plasma.
ʻO ka nānā paʻakikī o ka Lā
No ka mea hiki ke nānā i ka loko o ka Lā, ua hoʻohaʻahaʻa ʻia kona mechanics i loko mai ka hana i hana ʻia ma ka ʻili. A i loko o nā nalu acoustic ka ʻike waiwai e pili ana i nā mea e hiki mai ana 'ma lalo'. Hoʻokumu pinepine ʻia lākou ma kahi kokoke i ka ʻili a laila ʻike ʻia i loko, kahi e kani ai lākou, e hana ana i nā oscillations acoustic e hiki ke hōʻike i nā hiʻohiʻona o ka loko o ka Lā.
ʻO ia ka mea a ka poʻe ʻepekema e hana nei ma ka nānā ʻana i ʻumi makahiki o ka ʻikepili mai ka satellite Heliosismic and Magnetic Imager. Akā i loko o lākou ua loaʻa iā lākou kahi hōʻailona kūpaʻa e hōʻike ana i ke ʻano o kahi ʻano nalu i ʻike ʻole ʻia ma mua.
Ua ʻimi ka poʻe noiʻi i nā wehewehe hiki ke loaʻa: ʻo nā nalu i hana ʻia e nā māla magnetic i loko o ka Lā; mai nā nalu lā ʻē aʻe i kapa ʻia he hawewe gravity; a i ʻole e pili ana i ka hoʻoemi ʻana o ka plasma. Akā ʻaʻohe o kēia mau manaʻo i kūlike i ka ʻikepili.
"ʻO ka loaʻa ʻana o kahi pūʻulu o nā nalu ʻaʻohe wehewehe," wahi a Hanson, "he ... hoʻohauʻoli a hoihoi, no ka mea i kēia manawa ʻo ka paʻakikī ka mea e wehewehe ai i ke ʻano o ia mau mea. Ua nele mākou i kahi mea i ko mākou ʻike ʻana i ka Lā."
ʻO ka hopena, ma ka Honua?
ʻO ka mea hoihoi, hiki ke loaʻa ka hopena o ka mea pohihihi ma ʻaneʻi ma ka Honua. ʻOiaʻiʻo, i loko o nā moana o ko kākou honua no ka mea aia kekahi ʻano nalu like, i kapa ʻia ʻo Rossby wave, ʻaʻole hiki ke hoʻonele i kahi e hiki ai i nā mea noiʻi ke wehewehe. "I ka loaʻa ʻole o kahi hoʻonā no kēia mau nalu lā a me nā nalu Rossby moana," wahi a Hanson, "hiki iā mākou ke ʻōlelo wale aku he pono ke noiʻi ʻana i nā mea like."
Eia nō naʻe, ke manaʻo nei ka mea ʻepekema hiki i ka hopena o ka enigma ke hele i kekahi ʻano o ka hui pū ʻana o ka magnetism, ka umekaumaha a me ka hoʻopili ʻana, ʻoiai ʻaʻole hiki iā ia ke maopopo i kēia. "He mea paʻakikī loa ke noʻonoʻo - wehewehe ʻo ia - kahi hiʻohiʻona kahi o kēia mau mea ʻaʻole e pāʻani i kekahi ʻano hana i ka hoʻohuli ʻana i kēia 'mode wikiwiki'". Akā ʻaʻole hiki i nā mea noiʻi ke noʻonoʻo i nā ʻano hana ʻē aʻe, no laila ke lana nei ko lākou manaʻo e hiki i nā loiloi hou a me nā kikoʻī kikoʻī ke wehewehe i kēia mau nalu ʻē i ka wā e hiki mai ana.
Ua ʻōlelo ʻo Shravan Hanasoge, ka mea kākau o ka noiʻi: "ʻO ke ʻano o nā hawewe retrograde kiʻekiʻe a me ko lākou kumu he mea pohihihi maoli ia a hiki ke hōʻike ʻia ke pāʻani nei ka physics hou. ʻO kekahi me ka hiki ke hoʻokahe i ka ʻike e pili ana i ka loko o ka Lā i hiki ʻole ke ʻike ʻia. "
