polar trough

nā hopena o ka pā polar

Ma ka meteorology ʻike mākou i nā ʻōnaehana mua e neʻe i nā kiʻekiʻe a hiki ke ʻike ʻia ma ka mālama ʻana i nā laina ma ka palapala ʻāina e hoʻomaopopo pono i ka neʻe ʻana o ka makani. Ma keʻano laulā, ʻaʻole hiki ke hoʻomaopopo ʻia e ka lehulehu. I kēia hihia, nui ka poʻe i ʻike ʻole i ka mea a polar trough a me kona manaʻo ma ka palapala ʻāina.

No kēia kumu, e hoʻolaʻa mākou i kēia ʻatikala e haʻi iā ʻoe i ke ʻano o ka lele lele, ke ʻano o kona kumu a me kona ʻano.

He aha ke ala maʻamau

hana hau

Aia nā wehewehe ʻokoʻa o ke ʻano o ka pahu i loko o ka palapala ʻepekema. Hiki ke ʻōlelo ʻia he wahi elongated o ke kaomi haʻahaʻa haʻahaʻa ma ka ʻili a i ʻole ka ea o luna. O ka maʻamau, ʻaʻole pili ʻia me kahi loop pani, no laila ua hoʻohana ʻia e hoʻokaʻawale iā ia mai kahi palena liʻiliʻi. Aia i mua ke kua. ʻOi aku ka like o kēia wehewehe ʻana me ka manaʻo o nā kahawai dynamic a barometric. I kēia mau hihia, ʻo ka loaʻa ʻana o ka liʻiliʻi liʻiliʻi a i ʻole ke kaomi barometric kiʻekiʻe kahi i kokoke ʻole ai ka contour o ke kaumaha e lawa ai ke kaha kiʻi awāwa.

Me ka pahu kuʻuna, ua ʻike ʻia ka manaʻo o ka pahu hoʻohuli. I kēia hihia, ʻaʻole like nā isobars i ka ʻaoʻao like me nā puʻuwai nui ma mua o ka mea maʻamau. Hiki ke ʻōlelo ʻia ka hoʻohaʻahaʻa i ka ʻākau mai kahi haʻahaʻa.

He aha ke ala pola

ʻO ia ke komo ʻana o ke ea anu mai ka Arctic, no laila e hoʻohaʻahaʻa mau i ka mahana. He ʻāpana o ka lewa me ka haʻahaʻa haʻahaʻa e pili ana i kahi ʻāpana pili i ka pae like. Kapa ʻia ʻo ia he pā no ka mea he ʻano V, me ka ʻili concave i ke kaomi haʻahaʻa.

Hana ʻia ia i ka wā e neʻe ai nā ea i ka lewa. Ke hele mai ka makani komohana mai ka Pole ʻĀkau, haʻahaʻa ka latitu a kiʻekiʻe ka lewa. He mea maʻamau ka neʻe ʻana mai ke komohana a hiki i ka hikina a hele pū ʻia me ka nui o ka ao ma nā pae āpau. I ka meteorology, pili pinepine nā hāʻule o ka mahana me nā ʻino a i ʻole nā ​​​​mua.

ʻO nā ʻokoʻa ma waena o kahi pā polar a me DANA

ʻauwai polar ma ka palapala ʻāina

ʻO kahi pā i ka wā e piʻi ai ka nui o ka ea mehana a maʻemaʻe ma kahi wahi elongated o ka haʻahaʻa haʻahaʻa e kū ana ma waena o ʻelua mau wahi o ke kaomi kiʻekiʻe (anticyclones), hoʻokumu ʻia e nā ea maʻalili, ʻoi aku ka nui o ka ea e wili ai i loko a hana i kahi hoʻomohala kū pololei o nā ao a me ka ua e hele pū ana me lākou. No laila, pili ia i kahi puʻuwai barometric elongated aia ma waena o ʻelua anticyclones, a i ʻole, ʻelua mau ʻāpana anticyclonic me nā ʻano ʻokoʻa iki.

ʻO ka DANA kahi hanana haʻahaʻa haʻahaʻa e hoʻokaʻawale a neʻe kūʻokoʻa i ka ea ma lalo o ke komohana. Hiki ke kū mau nā kulu wai anuanu no nā lā a i ʻole i kekahi manawa neʻe i ke komohana, ma ka ʻaoʻao ʻē aʻe o ke kahe o ka lewa.

makani a me ka makani ino

polar trough

ʻAʻole like me nā pōʻino a i ʻole nā ​​makani ʻino, he ʻano pōʻai a liʻiliʻi paha ke ʻano, ʻoi aku ka nāwaliwali o nā makani e hoʻopuka ana i nā ʻauwaha no ka mea e hemo koke ko lākou ikehu i ka piʻi ʻana o ka nui o ka ea i loko o ka pā ponoʻī. Eia naʻe, ʻO ke kuhikuhi o kēia mau makani he kumuhana i aʻo iki ʻia a huikau pinepine, ʻoiai ua wehewehe nui lākou i nā ʻano hana e hoʻopuka ai i ka ua maʻamau a hoʻomau i ka ua.

He ʻano paʻakikī a paʻakikī kēia e wehewehe i nā huaʻōlelo ʻāina, a ʻaʻole maʻalahi ka ʻike ʻana ma nā palapala ʻāina meteorological no ka mea, me ka nānā ʻole i ke alo o ke ao lōʻihi e ʻike ʻia ma ke koʻi o ka ʻauwai, hiki ke hiki i kahi ana nui (mau kaukani km. ), ʻo nā anticyclone ʻelua e pili ana iā ia i ʻike ʻia ma muli o ka nele o nā ao a me ko lākou nui nui. Akā, pono kākou e hoʻomanaʻo, aia nā makani a puni nā anticyclones ma ka ʻaoʻao ʻē aʻe i nā ʻino, ua hoʻololi lākou i ka uaki: no ka mea, ʻelua mau anticyclones ma ke ʻano he kikowaena o ka hana, hoʻopuka lākou i ka makani, a ʻo ka pilina ma waena o lākou aia ma ke "awāwa"., ka hana ʻana i ke awāwa, hoʻololi ka makani i ka uaki a puni ke kahawai ponoʻī

ʻO ka ʻōlelo koʻikoʻi, ua like loa nā ʻauwai lewa me nā ʻino ʻino, ma ka liʻiliʻi loa. ʻO nā ʻokoʻa ʻike nui ʻia ma ke ʻano (ka pōʻai i ke ʻano o ka makani ʻino, elongated i ka hihia o kahi pā) a me kona nui: ʻO Hurricane Sandy, ka mea nui loa ma ka moʻolelo (1.800 kilomita ke anawaena) kahi e hiki ai iā lākou ke hiki i ka lōʻihi o 16.000 km a ʻoi aku paha.

Akā, hiki ke ʻike ʻia nā ʻano like o ka pōʻaiapuni o ka lewa ma kēia mau ʻano meteorological: ʻo nā kaula ua ma nā hihia ʻelua e hōʻike ana i ka ʻaoʻao like a me ka hoʻomohala ʻana, e huli ana i ka ʻaoʻao ʻākau ma ka ʻaoʻao ʻākau a me ka uaki ma ka ʻaoʻao hema.

ʻO ka mea nui, neʻe pinepine ka ʻauwai polar mai ke komohana a i ka hikina, a hele pū ʻia me nā pae like ʻole o ka uhi ao.

kū ʻole o ka lewa

Ma lalo o kekahi mau kūlana, ua palapala ʻia nā pahu e like me nā hiʻohiʻona e pili ana i ke ʻano o ka ua ʻaʻole mua i nā mahina mahana, i hoʻokumu ʻia e ka convective foci o ka diurnal evolution. Kuhi ʻia kēia mau poho hypothetical i kaha ʻia ma ka palapala ʻāina no ke kākoʻo ʻana i nā kula ao, ʻoi aku ka wānana a i ʻole ka nānā ʻana i nā māla ua, i unuhi pinepine ʻia he mau laina o ka hoʻololi ʻana a i ʻole ka pōʻino ma muli o ka convection.

ʻO ka manaʻo, i kekahi manawa ua hoʻokumu ʻia kēia mau laina paʻa ʻole e nā pā wela wela a me nā kuala cryogenic, hiki iā ia ke hana i kahi ʻano kūpono no ka convection. Ma keia manao, huki pinepine ʻia nā pā ma hope o ka laina ua, e pili ana me ka hoololi aniau e pili ana i ka convection a me ka ino.

E like me kāu e ʻike ai, lilo ka meteorology i mau ʻaha mele paʻakikī e hiki ke alakaʻi i ke ola ʻana o kekahi mau ʻano meteorological. Me kēia ʻatikala ke manaʻo nei mākou e hoʻopau i nā kānalua āpau e pili ana i ke ola ʻana o nā polar troughs. No laila, ke manaʻolana nei au me kēia ʻike hiki iā ʻoe ke aʻo hou aʻe e pili ana i kahi pahu polar, pehea i hana ʻia ai a pehea kona hopena.


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.
