Te Rangahau i te Hononga i waenga i te Ua me te Pāmahana o te Mata o te Moana i ngā Wai Tropical
Pendahuluan
He rohe matua ngā wai pārūrū i roto i te pūnaha āhuarangi o te ao nā te mea he nui ngā hihi o te rā e whiwhi ana i te tau katoa, ā, ko rātou hoki ngā pokapū o te hanganga kapua āwhiowhio. I tēnei rohe, he maha ngā wā e hono tata ana te rerekētanga o te ua ki ngā āhuatanga o te moana me te āhuarangi, inā koa te pāmahana o te mata o te moana (SST). Ka taea e te ua nui te whakaoho i ngā waipuke, ngā horo whenua, me te whakararuraru i ngā mahi ōhanga, engari ko te korenga o te ua ka taea te whakararu i te tauraki me te pēhi i te rāngai ahuwhenua me te wātea o te wai. Te Mārama te whanaungatanga i waenga i te ua me te SST i ngā wai pārūrū He mea nui kia whakapai ake i ngā āheinga ki te matapae i te huarere me te āhuarangi, inā koa i ngā tauine ā-wā me ngā tau i waenga i ngā tau.
Ko te rangahau i te whanaungatanga i waenga i te SST me te ua e ahu mai ana i te mātāpono ko te moana te pūtake matua o te kohu wai o te āhuarangi. Ka pā nui ngā panoni iti o te SST ki te mimiti, te pumau o te āhuarangi, me te hanganga kapua. Heoi, ehara i te mea ngāwari noa tēnei whanaungatanga; ka pāngia e te hau, te "makuku papamuri" o te āhuarangi, te tohanga o te ua, ngā ngaru o te āhuarangi pārūrū, tae atu ki ngā āhuatanga nui pēnei i te El Niño–Southern Oscillation (ENSO) me te Indian Ocean Dipole (IOD). Nō reira, me whai huarahi e whakakotahi ana i te māramatanga ā-tinana me te tātari raraunga hei aromatawai i te wā me te wāhi e noho ai te SST hei pūtake matua o ngā rerekētanga ua.
Ngā Ariā Taketake o te Pāmahana o te Mata o te Moana me te Ua
Ko te SST te pāmahana o te paparanga o runga rawa o te moana (i te nuinga o te wā he torutoru mirimita ki te mita) e taunekeneke tika ki te āhuarangiI ngā rohe werawera, ka whakanuia ake e ngā SST mahana ake te rere o te wera huna mā te mimiti. Ka taea e te hau makuku e piki haere ana i puta mai i te wera o te mata te hanga kapua convective me te whakaputa ua, ina koa mēnā he tino koretake te āhuarangi, ā, he tikanga hiki pēnei i te huihuinga o te hau mata.
Ko te nuinga o te ua pārūrū e akiakihia ana e te convection—te tukanga e piki ake ai, e whakamatao ai, e whakapūmau ai ngā hau mahana, makuku. Nā te mea e whakawhirinaki ana te convection ki te tuku mai i te mamaoa wai me te pūngao, e kiia ana ko te SST te "wahie" mō te ua. Heoi, kāore ngā SST teitei e hua ake ai he ua nui mena he nui te hekenga o te rangi, he hau maroke e tomo mai ana, he hau rānei e aukati ana i te tipu o te kapua.
Ngā Tikanga Ā-tinana e Hono Ana i te SST me te Ua
Ka taea te mārama ki te whanaungatanga i waenga i te SST me te ua mā roto i ētahi tikanga matua:
1. Te mimiti me te rerenga wera huna
Ko te pikinga ake o ngā SST ka whakanui ake i te pikinga o te pēhanga kohu wai i waenga i te mata o te moana me te āhuarangi, ka piki ake te mimiti. Ka noho tēnei kohu wai hei poraka hanga mō ngā kapua. I raro i ngā āhuatanga hau mata pai, ka nui ake te whai hua o te mimiti. Nō reira, ko ngā wāhi he mahana ake ngā SST ka nui ake te pūmanawa mō te ua.
2. Te Pūmautanga o te Āhuarangi me te Whakawhitiwhiti
Ka whakamahana ngā SST mahana i te hau e tata ana ki te mata, ka whakanui ake i te kore pumau o te āhuarangi. Mā tēnei kore pumau ka āwhina i te whakawhiti me te hanganga o ngā kapua cumulonimbus. Heoi, ki te mahana hoki te āhuarangi o runga, ki te hurihanga rānei, ka taea te aukati i te whakawhiti.
3. Te Huinga me te Whakawhitinga ā-Rohe
Ka taea e ngā rerekētanga o te SST te hanga i ngā rerekētanga pēhanga me te whakaoho i ngā tohanga ā-rohe pērā i ngā hau moana, i ngā rohe huihuinga rānei i runga i ngā wai mahana. Ka whakatairangahia e ngā hau mata huihuinga te pikinga o te hau, ka piki ake te tūponotanga o te ua. I te tauine nui ake, ka taupatupatu te huihuinga i roto i te Rohe Huihuinga Inter-Tropical (ITCZ) ki ngā wāhi he SST mahana.
4. Urupare mō te ua i runga i te SST
He mea whakamīharo, ka pā hoki te ua ki te SST. He maha ngā wā ka haere tahi te ua nui me te pikinga o te taupoki kapua, ka whakaiti i te hihi o te rā e tae atu ana ki te mata o te moana, ka heke te SST. Hei tāpiri, ka taea e te ua me ngā hau kaha te whakanui ake i te ranunga o ngā paparanga o runga o te moana, ka hua ake wai matao mai i raro ki te mataKo te tikanga o tēnei he hononga e rua ngā taha i waenganui i te SST me te ua, ā, ka taea te hanga i tētahi huringa urupare.
Ngā Rerekētanga o te Wā i ngā Whenua Pārūrū
I roto i te tini ngā rohe pārūrū pērā i a IndonesiaHe kaha te awe o te pūnaha hau mātao ki te hekenga o te ua. I te wā hau mātao, ka haria e ngā hau ngā hau makuku mai i te moana nui ki uta, ka piki ake te ua. He mahi tā te SST ki te tuku i te mamaoa wai, engari ko ngā tauira hau o te wā te nuinga o te wā e whakahaere ana i te tohatoha o te ua. I tetahi atu taha, i te wā hau mātao maroke, ahakoa ka noho mahana tonu ngā SST o te rohe, ka taea e te hau maroke, te kaha rānei o te hekenga te aukati i te hanganga o te kapua. Koinei te take ka rerekē ai te hononga SST-ua i ia wā.
I roto i ngā wai pārūrū, ka taea hoki e ngā rerekētanga ā-wā, pērā i te Madden–Julian Oscillation (MJO), te whakakaha, te whakangāwari rānei i te ua i roto i te wā 30–60 rā. Ina pahemo te wāhanga whakawhiti o te MJO, ka piki ake te ua, ā, he maha ngā wā ka haere tahi me te whakamatao SST nā ngā kapua me te whakaranu. Ina heke te wāhanga, ka taea e te SST te whakamahana anō nā te pikinga o te hihi o te rā. E whakaatu ana tēnei āhuatanga i te tauira "ka mua te SST i te ua" i ētahi āhuatanga, ā, "ka mua te ua i te SST" i ētahi atu āhuatanga.
Tauine ā-tau: ENSO me IOD
Ko te āhuatanga ENSO tētahi o ngā tino take o te rerekētanga o te āhuarangi pārūrū. I te wā o El Niño, ka nekehia te pokapū o te whakawhiti ki te rawhiti e te mahanatanga o te Moana-nui-a-Kiwa waenga-mā-rāwhiti. He maha ngā rohe moana, pērā i a Indonesia, e pāngia ana e te hekenga o te ua nā te hekenga o te whakawhiti, ahakoa kāore i te tino mātao ake ngā SST ā-rohe. I tētahi atu taha, ka kaha ake te whakawhiti a La Niña ki te uru o te Moana-nui-a-Kiwa, ā, ka piki ake te ua ki Indonesia.
He nui te mahi a te IOD i roto i te Moana Iniana . I te wā e pai ana te IOD, ka mātao ake ngā wai i te taha hauauru o Sumatra–Java, engari ka mahana ake te Moana Iniana ki te taha hauauru. Ka whakaitihia e tēnei mātao tata ki Initonīhia te mimiti me te kawe hau, ka puta ai he tauraki i te tonga o Initonīhia. Ina he kino te IOD, ka mahana ake ngā wai tata ki Initonīhia, ā, ka tautoko i te pikinga o te ua, inā koa ka haere tahi mai me te La Niña. Ka taea e te taunekeneke o te ENSO me te IOD te whakakaha, te ārai rānei i ngā pānga o tētahi ki tētahi, nō reira me whai whakaaro ngā tātaritanga o te whanaungatanga i waenga i te SST me te ua ki ngā mea e rua.
Huarahi Tātari o te Hononga SST me te Ua
Ko ngā rangahau pūtaiao e whakamahi ana i ngā raraunga tirotiro me te tātari anō, pērā i te SST amiorangi, te ua amiorangi (TRMM, GPM), me ngā raraunga teihana ua. Ko ētahi o ngā tikanga e whakamahia whānuitia ana ko:
– Te Hononga ā-Wāhi me te Whakamuri: Ka aromatawai i te kaha o te whanaungatanga i waenga i te SST me te ua i runga i tētahi whatunga motuhake. Heoi, kāore te hononga e tohu i te take i ngā wā katoa.
– Te Hononga Whakaroa (Te Hononga ki te Whakaroa Wā): Ka whakamātautau mēnā ka puta ngā huringa o te SST i mua i ngā huringa o te ua, i mua rānei i ngā huringa o te ua. He mea nui tēnei hei aromatawai i te pūmanawa matapae.
– Te Tātaritanga Āhuatanga me te Tātaritanga Ngaru: Te tautuhi i ngā āputa i waenga i te wā me te ā-tau e hono ana i ngā mea e rua.
– Te Whakakotahitanga o ngā Takahanga: Te whakataurite i ngā āhuatanga o te SST i te wā ua nui me te maroke nui.
– Ngā Tauira Tau me ngā Tauira Hononga: Te whakamātautau i ngā tikanga ā-tinana mā te taunekeneke i waenga i te āhuarangi me te moana.
I roto i te mahi, me aro atu hoki ngā kairangahau ki ngā whakaaro rerekē ki ngā raraunga amiorangi (hei tauira, te uaua ki te ine i te ua i ngā wāhi maunga, i te wā rānei e kapi ana i ngā kapua) me te taumira ā-wāhi, nā te mea ka tino pāngia te rohe e ngā tukanga whakawhiti hiko.
Ngā Pānga mō te Matapae me te Whakahaere Mōrearea
He nui ngā painga o te mārama ki te whanaungatanga i waenga i te SST me te ua i ngā wai pārūrū. Tuatahi, he ngāwari te aroturuki whānui me te haere tonu i te SST ki te whakataurite ki te ua whenua, e whakawhirinaki ana ki tētahi whatunga o ngā teihana. Mena he kaha te whanaungatanga SST-ua i tētahi rohe me tētahi wā motuhake, ka taea e te SST te whakamahi hei tohu wawe mō ngā matapae ua ā-wā. Tuarua, ka taea e ēnei mōhiohio te tautoko i ngā whakatūpato tauraki wawe, te whakahaere puna wai, te whakaritenga whakato, me te whakarite mō te waipuke.
Heoi, he tino uaua ngā pūnaha pārūrū. Ko te angitu o ngā matapae ehara i te mea ko te SST anake engari ko ngā āhuatanga o te āhuarangi pērā i te hau, te haumākū, me ngā whanaketanga nui (ENSO, IOD, MJO). Nō reira, ko te huarahi pai ko te whakauru: te whakakotahi i ngā tohu SST me ngā tohu āhuarangi me ngā tauira matapae e ahu mai ana i te tinana me te tatauranga.
Whakamutunga
E whakaatu ana ngā rangahau mō te whanaungatanga i waenga i te ua me te pāmahana o te mata o te moana i ngā wai pārūrū i tētahi whanaungatanga kaha engari kāore i te rārangi tonu. Ko ngā SST mahana ake ka whakanui ake i te mimiti me te tautoko i te whakawhiti, ka piki ake pea te ua. I tetahi atu taha, ka taea e te ua me ngā kapua te whakamatao i ngā SST mā te whakaiti i te irahiko me te ranunga moana. Ko te rerekētanga o te wā, o roto i te wā, me te tau - i awehia e ngā hau marangai, te MJO, te ENSO, me te IOD - ka whakatau ko te SST te kaiārahi matua o te ua, ā, ko te wā he nui ake te mana o ngā āhuatanga o te hau. Mā te tātari raraunga tika me te mārama ki ngā tikanga ā-tinana, ka taea te whakamahi i te whanaungatanga SST-ua hei whakapai ake i ngā matapae āhuarangi me te whakaiti i te huringa āhuarangi. mōrearea āwhati te hydrometeorology i ngā rohe pārūrū.
