Hāʻule ke kahawai ʻo Gulf

nā mea ulu a me nā holoholona hiki ke pōʻino

ʻO ka Atlantic Current, he "conveyor belt" nui o ka moana e lawe ana i ka wai mahana mai ka ʻāina ākea a hiki i ka ʻĀkelanika ʻĀkau, ke lohi nei a ma ke ʻano o ka hāʻule ʻana, kahi e hoʻololi ai i ka mahana ma ʻEulopa. Ua aʻo ka poʻe ʻepekema e pili ana i kēia no nā makahiki. ʻAʻole i hōʻoia wale ka noiʻi hou i ka nalowale o ka ikehu i kēia manawa, akā wānana pū kekahi i kahi kū koke i ka wā e hiki mai ana. E loaʻa i ka laka ka hopena ma waena o ʻEulopa, e hoʻoulu ai i kahi maloʻo lōʻihi a e hoʻokau i ka hapa nui o ka ʻāina i kahi hoʻoilo mau loa. Kūkākūkā nā kānaka ʻepekema hāʻule kahawai awāwa he hopena maikaʻi ʻole no ke kaiapuni honua.

No laila, e hoʻolaʻa mākou i kēia ʻatikala e haʻi iā ʻoe i nā mea āpau e pono ai ʻoe e ʻike e pili ana i ka hāʻule ʻana o ke kahawai ʻo Gulf Stream.

ʻĀpana ʻAkelanika

hāʻule ke kahawai awāwa

Ua ʻōlelo kekahi physicist atmospheric mai ke Kulanui ʻo Complutense o Madrid: "I ka manawa e hana ai kēia, e pau ka neʻe ʻana o nā wai wela wela i ka ʻāina ʻo ʻAkelanika ʻĀkau. e lilo lākou i wai anuanu a loaʻa ka hopena i ke aniau o ka ʻāina. Wahi a ke aʻo ʻana, i paʻi ʻia ma ka puke pai Nature, ʻo ke ʻano o kēia wai "conveyor belt" - i ʻike ʻia ʻo ka Atlantic Meridional Overturning Circulation -AMOC- ua hāʻawi i nā hōʻailona lawa e pili ana i kahi "koke koke".

ʻO ke kahe ʻana o ka thermohaline (THC) kekahi o nā mea koʻikoʻi o ka holo moana ma ka pae honua. ʻO ke kumu, ʻo ia kekahi o nā mea e hoʻoholo ai i ke aniau honua ma muli o kona komo nui ʻana i ke kahe wela o ka honua. ʻO ka AMOC, aia i loko o kēia kāʻei conveyor, hoʻoponopono i ka mahana ma ka ʻAkelanika Hema. "Mahalo iā ia, ʻoi aku ka mahana o Madrid ma mua o New York, ʻoiai aia lākou ma kahi latitude like", wahi a ka physicist atmospheric.

ʻO kāna hana i hōʻike ʻia e ke au o ka wai mehana a me ka paʻakai e hele ana i ka moana Atlantika luna, aʻo kekahi au e lawe i nā wai anuanu a hohonu i ka hema. a laila e lilo ia i ʻāpana o ke kahe thermohaline.

Eia naʻe, ua pau ka mahu o ka ʻenekini e hoʻokele nei i kēia au o ka ʻAkelanika i nā makahiki he ʻumi i hala aku nei, a ua manaʻo ʻia ʻo ka hoʻololi ʻana i ke aniau ke kumu. "ʻAʻole maopopo, akā nui nā manaʻo e kuhikuhi i ka hoʻoheheʻe ʻana o Greenland ke kumu nui o kēia lohi," wahi a González, no ka mea, ʻo ia ka hau ma nā wahi anuanu o ʻEulopa e hiki ai i nā au o ka ʻAkelanika ke hana.

Ua like kēia me ka piʻi nui ʻana o ka wai ʻili ma muli o ka hoʻololi ʻana i ke aniau, e lawe mai ana i ka ʻōnaehana hoʻokahi ʻanuʻu kokoke i ka hāʻule ʻana.

E aʻo i ka hāʻule ʻana o ke kahawai ʻo Gulf

pehea ka holo ʻana o ka thermohaline

ʻAʻole i hōʻike ʻia ka haʻawina i ka wā e hiki mai ai ka hanana, akā ʻaʻole ia e kāpae i ka hiki ʻana mai i nā makahiki e hiki mai ana. ma mua paha o ka hopena o ke kenekulia. "He hopena pōʻino kēia ma ʻEulopa a me ka honua holoʻokoʻa," no ka mea e "hoʻololi koke i ke aniau," i hoʻopau ai nā mea noiʻi.

ʻO ka ʻoiaʻiʻo, ua manaʻo ʻia kēia ʻano he "kumu kuhi o ka ʻōnaehana aniau," ʻo ia hoʻi i ka wā e hiki mai ai, ʻaʻole e like hou ke ea o ka ʻāina.

Nā hopena o ka hāʻule ʻana o ke kahawai ʻo Gulf

hāʻule kahawai awāwa

Aia i loko o ka papa inoa i hōʻuluʻulu ʻia e ka Intergovernmental Panel on Climate Change (IPCC) he ʻeiwa mau wahi hoʻololi ʻana i ke aniau i hoʻopilikia nui ʻia a i ʻole e nalowale ana. ʻO nā mea ʻeiwa ʻo ia ka hau kai Arctic, ka ʻili hau Greenland, ka nahele boreal, permafrost, ka ʻōnaehana o kēia manawa ʻo Atlantika, ʻo ka wao ua Amazon, nā ʻākoʻa wai mahana, a me ka ʻili hau o ka Moana Hema ma West Antarctica a me Asia Hikina. Hoʻopili ʻia kēia mau ʻōlelo aʻoaʻo a pau, no laila pili ka mea e pili ana i kekahi.

"He ʻoi aku ka maikaʻi o kēia kūlana ma mua o ka hoʻomehana ʻana, no ka mea ke ʻike mālie ʻia kona hopena, akā naʻe, he hoʻololi kumu kēia e loaʻa mau nā hopena i manaʻo ʻole ʻia," i ʻōlelo ai ʻo ia. ʻO nā hopena hiki ke hoʻemi ʻia ka ua, ʻoi aku ka nui o ka uhi hau ma nā ʻāpana ʻē aʻe o ʻEulopa, nā pilikia mahiʻai a i ʻole ke kiʻekiʻe o nā hanana e like me nā ʻino ʻoi aku ka ikaika.

ʻO ka mea e hiki mai ana, e like me kā González Alemán i ʻōlelo mai ai, ʻoiai ʻoiai ke ʻano nei kēia mau hopena e kūʻē i ka hoʻololi ʻana i ke aniau a i kekahi ʻano kaulike, ʻaʻole paha kēia ka hihia.

"I kekahi mau wahi hiki iā ia ke kaulike i nā hanana ʻelua, ma nā wahi ʻē aʻe hiki ke hōʻemi i ka hopena o ka hoʻololi ʻana i ke aniau a ma nā wahi ʻē aʻe hiki ke hoʻonui i ka hopena o ka hoʻololi ʻana o ke aniau," i ʻōlelo ai ka poʻe noiʻi, e koi ana ʻo ka hopena wale nō o ia hāʻule ʻana ʻo ia. ʻoi aku ka paʻakikī o ka wā e hiki mai ana. "ʻAʻole mākou ʻike i nā hopena āpau e hiki ke loaʻa iā ia, a hiki ke loaʻa nā hanana hiki ʻole ke ʻike ʻia," wahi āna.

Ka hopena pololei ma ka Atlantika

Hōʻike ka noiʻi e hoʻokokoke ana mākou i kahi paepae koʻikoʻi ma waho aʻe o ka hiki ke hāʻule ka ʻōnaehana kaʻa. Hōʻike kēia hana i nā mea he nui e hoʻonui i ka hopena pololei o ka hoʻomehana ʻana o ka Atlantika i kona kahe ʻana.

Hoʻokomo ʻia kēia mau mea i nā kahe wai maʻemaʻe mai ka hoʻoheheʻe ʻana o ka hau hau Greenland, ka hehee o ka hau kai, hoonui ka ua a me ka wai muliwai. ʻO ka wai maʻemaʻe e hoʻemi i ka manaʻo o ka wai ʻĀkelanika ʻĀkau e pohō hohonu mai ka ʻili, kekahi o nā mea hoʻokele o ka haunaele.

ʻO ka Atlantic Meridional Circulation he au moana nui e hoʻoponopono ana i ke aniau o ka Honua no ka mea, lawe ʻo ia i ka wai mehana mai ka ʻili ma nā latitu kiʻekiʻe, hoʻomaʻamaʻa i ka ea, pohō, a hoʻi i ka equator. No ka laʻana, he kuleana no Sepania, e leʻaleʻa ʻoi aku ka māmā o ke ea i hoʻohālikelike ʻia me ke koena o ka honua ma ko mākou latitu like.

Inā mahana ka Arctic, e maʻalili ʻo ʻEulopa no ka mea ke komo ka nui o ke anuanu a me ka liʻiliʻi o ka wai paʻakai i loko o ka ʻAkelanika, ʻoki ia i ke kahe o ka wai mehana mai ʻAmelika Hui Pū ʻIa a i ʻEulopa, kahi e hāʻule ai ka mahana o ka honua ma ʻEulopa Komohana, no laila ka e neʻe ka mahana i kahi pae e like me ka mea i hoʻopaʻa ʻia ma ʻAmelika ʻĀkau ma ka latitu like.

Manaʻo wau me kēia ʻike hiki iā ʻoe ke aʻo hou e pili ana i nā hopena o ka hāʻule ʻana o ke kahawai ʻo Gulf Stream.


Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.

E lilo i mea mua e wehewehe

E waiho i kāu manaʻo

Kāu leka uila aae? E,ʻaʻole e paʻiʻia.
