wahi anu loa ma ka honua

Ua ʻike mua ka poʻe ʻepekema ʻo ka haʻahaʻa haʻahaʻa loa i ana ʻia ma ka Honua ma kahi kuahau hau ma East Antarctica, kokoke i ka Pole Hema. Akā ua ʻike koke lākou hiki ke hāʻule ka mahana ma laila ma mua o nā mea i ana mua ʻia.

I ka makahiki 2013, ua ʻike ʻia ka ʻikepili o ka satellite i nā ʻeke lele o ke ea anuanu ma ka pāpū Hikina Antarctic ma waena o Argos Dome a me Dom Fuji - nā mahana i hāʻule i lalo o 135 degere Fahrenheit (zero 93 degere Celsius).

Eia nō naʻe, ʻo kahi loiloi hou o ka ʻikepili like e hōʻike ana ma lalo o nā kūlana kūpono, hiki i kēia mau mahana ke hāʻule i kahi kokoke i 148 degere Fahrenheit (minus 100 degere Celsius), ʻo ia paha ke anuanu loa e hiki ai i ka Honua, e like me ka mea noiʻi ma New study.

Ma ka Antarctica i uhi ʻia i ka hau, ʻo ka awelika o ka mahana i nā mahina hoʻoilo pōuliuli ma kahi o 30 degere Fahrenheit (emi 34.4 degere Celsius). No ka noiʻi hou, ua kālailai nā kānaka ʻepekema i ka ʻikepili i hōʻiliʻili ʻia ma Iulai a me ʻAukake ma waena o 2004 a me 2016. Ua ana ʻia nā mahana ma nā kīʻaha liʻiliʻi o ka East Antarctic Plateau kokoke i ka Pole Hema, ma kahi kiʻekiʻe o 12 kapuaʻi (467 mika). ua laha loa ka wela o ka hoopau ana i na mooolelo hou, aia ma na wahi he 3 ma na puu hoopuehu, he "wahi akea" o ka papu.

I ka hoʻoilo polar, he mau manawa lōʻihi me ka lani māmā a me nā makani nāwaliwali. Hui pū - ʻoiai e mau ana kēia mau kūlana - hiki iā lākou ke hōʻoluʻolu i ka ʻili o ka hau a me nā haʻahaʻa haʻahaʻa, e like me ke aʻo ʻana.

I ka makahiki 2013 a me ka noiʻi hou, ua hoʻohālikelike ka poʻe noiʻi i nā ana ukali wela o ka ʻili me ka ʻikepili i hōʻiliʻili ʻia mai nā kikowaena aniau ma ka ʻili o Antarctica. No ka loiloi hou, ua nānā hou nā mea noiʻi i ka ʻikepili o ka ʻili. I kēia manawa, ua aʻo pū lākou i ka maloʻo o ka lewa, ʻoiai ʻo ka ea maloʻo e hoʻemi koke i ka uhi hau, wahi a ka mea kākau alakaʻi noiʻi ʻo Ted Schampos, he kanaka ʻepekema noiʻi nui ma ka National Snow and Ice Data Center ma ke Kulanui o Colorado Boulder.

Me kēia hōʻano hou, ua hoʻoponopono hou lākou i ka ʻikepili ukali a loaʻa i kahi ana kūpono ʻoi aku ka maikaʻi o ka wela o ka iwi i loko o kēlā mau ʻeke kokoke i ka Pole Hema. Ua ʻike ʻia ka haʻawina ʻo nā ʻāpana like ma ka pāpū i ʻike mua ʻia ʻo ke anuanu loa ma ka Honua - ʻoi aku ka nui ma mua o kēlā, ma kahi o 9 degere Fahrenheit (5 degere Celsius).

E like paha ke anu o ka mooolelo hou e like me ka hiki ke hahau i ka Honua. "Pono ke anu a maloʻo loa no kekahi mau lā no ka puka ʻana mai o nā pae paʻakikī," wehewehe ʻo Scampos.

"Aia ka palena o ka lōʻihi o nā kūlana e hiki ai ke hōʻaʻalili i nā mahana haʻahaʻa loa, a ʻo ka nui o ka wela e hiki ai iā ʻoe ke loaʻa i ka lewa, no ka mea, ʻaʻole i loaʻa ka mahu wai i mea e hoʻokuʻu ai i ka wela. mai ka ilikai i kēia mau mahana,"
