Me pēhea te mārama ki ngā raraunga huarere mō te tuku kaipuke
Ko te mārama ki ngā raraunga huarere tētahi o ngā pūkenga tino nui o te ao whakatere. Ahakoa he kāpene kaipuke hokohoko koe, he kaihao ika tuku iho, he kaimahi poti whakangahau, he kaiwhakatere tauhou rānei, ka tino pāngia ō whakatau i te moana e ngā āhuatanga o te āhuarangi me te moana. Ko te huarere e ahua "pai" ana mai i uta ka tere te huri i ngā wai tuwhera. Nō reira, mā te āheinga ki te pānui me te whakamārama i ngā raraunga huarere ka āwhina i te whakatere kia haumaru ake, kia pai ake, kia whakamarie ake hoki.
Ka matapakihia e tēnei tuhinga te mārama ki ngā raraunga huarere mō ngā mahi tuku kaipuke: mai i ngā momo raraunga e whakamahia whānuitia ana, me pēhea te pānui i ngā mapi huarere , tae atu ki ngā tohu nui pēnei i te hau, ngā ngaru, te pēhanga hau, me te pūmanawa tupuhi.
1. He aha te hiranga o ngā raraunga huarere mō te tuku kaipuke?
I te moana, ka pā te huarere ki ngā āhuatanga katoa o te haerenga: te huarahi, te tere, te whakapaunga wahie, te pumau o te kaipuke, te haumaru o te hunga mahi kaipuke, me te mōrearea o te pakaru o ngā utanga. Ka taea e ngā hau kaha te whakaputa i ngā ngaru teitei me ngā ia o te mata. Ka taea e te ua nui te whakaiti i te tirohanga, te whakararuraru i te whakatere, me te whakanui ake i te mōrearea o te tukinga. Ka taea e te uira te kino i ngā taputapu hiko, engari ka taea e ngā awha te tino mōrearea ki te haumaru o te kaipuke .
Mā te pānui i ngā raraunga huarere, ka taea e ngā kaiwhakatere te:
– whiriwhiria he wā wehenga haumaru ake,
- karohia ngā wāhi morearea,
– te whakarerekē i te tere me te huarahi,
– te whakarite i te kaipuke me te kapa ki te aro atu ki ngā āhuatanga tino kino.
2. Ngā Pūtake Raraunga Huarere mō ngā Heramana
I ēnei rā, e taea ana te tiki raraunga huarere mai i ngā momo puna maha, mai i ngā puna tuku iho me ngā puna matihiko. Ko ētahi o ngā mea e whakamahia whānuitia ana ko:
1. BMKG (Initonīhia): e whakarato ana i ngā matapae huarere mō te moana, te teitei o te ngaru, te ahunga me te tere o te hau, me ngā whakatūpato mōrearea.
2. NOAA, ECMWF, me ētahi atu ratonga ā-ao: e whakarato ana i ngā tauira huarere ā-ao e whakamahia ana hei pūtake mō ngā tono huarere.
3. Te reo irirangi huarere me te NAVTEX: he tino whai hua mō ngā kaipuke e rere ana i tawhiti atu i te ipurangi.
4. Taupānga huarere moana: e whakaatu ana i ngā mahere hau, ngā ngaru, ngā ia, me ngā matapae mō ia hāora.
5. Te mātakitaki tika: he mea nui tonu te mātakitaki i ngā kapua, te ahunga o te hau, te pēhanga o te rangi, me ngā panonitanga o ngā ngaru hei whakamana i ngā āhuatanga tūturu.
Ko te mea pai, ka whakakotahi ngā kaiwhakatere i ngā puna maha kia kore ai e whakawhirinaki ki te matapae kotahi.
3. Ngā Tawhā Matua i roto i ngā Raraunga Huarere Moana
Kia whai hua ai ngā raraunga huarere mō te whakatere waka, me arotahi koe ki ngā tawhā e whai ake nei:
a) Hau
Ko te hau te mea tino taketake. Ko ngā raraunga hau ko:
– te ahunga o te hau (te pūtake mai o te hau),
– te tere o te hau (ngā noti, m/s, km/h rānei),
– te hau pūhau (ngā hau pūhau nui rawa atu i te hau toharite).
I te wā e whakatere ana, he maha ngā wā ka nui ake te mōrearea o ngā hau nui i te tere toharite nā te mea ka taea e rātou te whakararo ohorere i te kaipuke, te taupokina o ngā rā (i runga i te kaipuke whakatere), te pūkeri rānei o ngā ngaru.
Ko te tikanga whānui, ka taea e ngā hau kei runga ake i te 20–25 knots te waihanga i ngā āhuatanga whakararuraru, mōrearea hoki mō ngā kaipuke iti, i runga i te ahunga o te hau me te roa o te hopu (te tawhiti e pupuhihia ana e te hau i runga ake i te mata o te moana).
b) Ngā Ngaru (Ngā Ngaru/Pupuhi)
Ko ngā raraunga ngaru ka wehea kia:
– teitei ngaru / teitei ngaru nui (Hs): te toharite o te hautoru teitei rawa o te ngaru,
– wā / wā ngaru: te wā i waenganui i ngā tihi ngaru (hēkona),
– te ahunga / te ahunga o te ngaru.
He mea nui, ka rerekē te teitei o te ngaru kotahi i runga i tōna wā. Ko te ngaru 2-mita te roa me te wā o te 12–14 hēkona he roa ake, he hurihuri hoki, ko te ngaru 2-mita te roa me te wā o te 6–7 hēkona he koi ake, he pā kino ake. Mō te nuinga o ngā poti iti, he maha ngā wā ka hoha ake, ka mōrearea ake hoki ngā ngaru poto, kikī i ngā ngaru roa.
c) Te Pēhanga Hau
Mā te pēhanga hau (i roto i te hPa) ka āwhina i te pānui i ngā au o te huarere. Te kaupapa matua:
– te hekenga tere o te pēhanga: te tūponotanga o te kino haere o te rangi, te piki haere o ngā hau, te tūponotanga o ngā awha,
– te piki haere tonu o te pēhanga: ka pai ake te āhua o te rangi.
He mea nui tonu te pae ine huarere i runga i te kaipuke—ahakoa he taupānga huarere tāu—nā te mea e whakaatu ana i ngā āhuatanga o te rohe.
d) Te Ua me te Taupoki Kapua
Ka pā te ua nui ki:
- te kitea,
– te mōrearea o te kohu rangitahi,
– te tūponotanga o ngā hau kaha ā-rohe (te hau e heke ana ki raro),
– te whakamarie me te whakahaere o te papa.
He mea nui anō hoki te taupoki kapua hei aromatawai i ngā huringa o te rangi. Ko ngā kapua Cumulonimbus (CB) he tohu mō ngā mahi a te whatitiri, te uira, te ua nui, me ngā hau kaha ka puta ohorere mai.
e) Te tirohanga
He maha ngā wā ka warewarehia ngā raraunga tirohanga, engari he mea nui mō te haumaru. Ka taea e te kohu, te ua nui rānei te whakararuraru i te te whakatere tirohanga me te kimi kaipuke Ki te kore, ka tino uaua. Mēnā ka heke te tirohanga, me whakatinana ngā tikanga haumaru pēnei i te whakamahi i te radar, ngā pū, me ngā tere haumaru.
f) Ngā Au o te Moana (Au)
Ngā pānga o nāianei:
- te wā haere,
– te whakapaunga wahie,
– te āheinga ki te nekeneke,
– ngā āhuatanga o te ngaru.
He mea nui, ko ngā ia e neke ana i te taha o te hau ka taea te whakatōtika ake i ngā ngaru, ka nui ake hoki te mōrearea. Hei tauira, ko ngā hau kaha e neke ana i te taha o te ia ka taea te hanga i ngā "ngaru tū," arā, ngā ngaru e āhua teitei ake ana, e koi ake ana.
4. Me pēhea te pānui i ngā mahere huarere me ngā tohu taketake
He maha ngā matapae ka whakaaturia mā roto i ngā mapi. Anei ngā kaupapa matua:
a) Isobar me te Pokapū Pēhanga
He rārangi isobar e hono ana i ngā pūwāhi he rite te pēhanga hau.
– Ko ngā isobar tata e tohu ana i te pikinga pēhanga nui → he kaha te hau.
– Ko ngā isobar e tawhiti ana e tohu ana i te ngoikore o ngā hau.
Te pokapū pēhanga:
– Te pēhanga iti (L): he maha ngā wā ka puta mai te huarere kino, te ua me ngā hau kaha.
– Te pēhanga teitei (H): he mārama, he pumau hoki, ahakoa me mōhio tonu koe ki ngā hau e karapoti ana i te pūnaha.
b) Te Huarere o te Ao
He huihuinga o ngā momo hau rerekē te mata o mua. I runga i te mapi o te ao, ka kitea:
– matao: he maha ngā wā ka whai mai ko te hurihanga o te ahunga o te hau, te ua, ngā whatitiri,
– te mata mahana: he ōrite te tohatoha o te ua, ā, he roa ake te wā,
– te taha mua kua āraia: ngā āhuatanga uaua, te tūponotanga o te huarere kino.
Mō te whakatere, me tūpato te whakatata atu, te whiti rānei i te taha moana, nā te mea ka tere te puta o ngā panonitanga o te hau me ngā ngaru.
5. Te Hononga i ngā Matapae ki ngā Āhuatanga me ngā Huarahi o te kaipuke
Kāore e taea te whakamārama i ngā raraunga huarere me te kore he horopaki. He rerekē ngā waka iti i ngā waka nunui. Ko te kawenga, te āhua o te anga, te pokapū o te taumaha, me te wheako o te kapa e whakatau ana i ngā rohe haumaru. I te aromatawai i ngā matapae, whakaarohia:
1. Te ahunga o te hau ki te ihu o te waka
Mā te hau me ngā ngaru mai i mua (ngā moana matua) ka pā te waka ki ngā ngaru, ka whakaroa i te tere, ka tūpono hoki te pakaru. Mai i te taha (ngā moana kurupae) ka piki ake te tūponotanga o te hurihuri. Mai i muri (ngā moana e whai ana) ka taea e rātou te whakararu me te ngaru i roto i ētahi waka.
2. Te roa o te pānga ki ngā āhuatanga kino
He rerekē te pānga o te ngaru 2–3 mita te roa mō te haora kotahi i te ngaru 8-hāora. He take haumaru te ngenge o te kapa.
3. Ngā huarahi rerekē me ngā tauranga piringa
Me whakamahere tonu he wāhi piringa: he kokoru, he whanga tata, he wāhi rānei e marumaru ana mai i te hau matua.
4. Ngā panonitanga o ngā tai me ngā āhuatanga o te moana
I te awaawa, i te ngā wai whaiti, ka kino ake te haere o ngā ngaru i ngā ia tai mena kei te pā kino atu ki te hau.
6. Kia Mōhio ki ngā Tohu Whakatūpato Moata o te Huarere Kino
Haunga te whakawhirinaki ki ngā matapae, me mōhio ngā kaiwhakatere ki ngā tohu e whai ake nei:
– ka tere te heke o te pēhanga o te hau,
– ngā kapua pōuri e tipu poutū ana (cumulonimbus),
– ka marino whakarere te hau, kātahi ka pupuhi kaha (he tohu o te hau pūkeri),
– ngā huringa rerekē o te ahunga o te hau,
– he rārangi pōuriuri i te pae tawhiti.
Ki te puta mai ēnei tohu, whakaarohia te whakaiti i te rā (mō ngā kaipuke whakatere), te whakapūmau i ngā utanga i runga i te papa, te kati i ngā taupoki, te whakarerekē i te huarahi, me te whakahou i ngā mōhiohio huarere.
7. Ngā Hē Noa i te Whakamārama i ngā Raraunga Huarere
Ko ētahi hapa noa:
– te titiro noa ki te ata "mārama/kapua" me te kore e tirotiro i te hau me ngā ngaru,
– te kore aro ki te wā pupuhi me te ngaru,
– te nui rawa o te whakawhirinaki ki tētahi tono/tauira,
– te kore e aro ki ngā rerekētanga o ngā āhuatanga o te takutai moana me te takutai moana,
– te kore e whakahou i te matapae huarere i mua i te wehenga atu, i te wā hoki o te haerenga.
He hihiri te huarere; he mea nui ngā whakahoutanga auau.
Te Katinga
Ko te mārama ki ngā raraunga huarere mō te whakatere waka he whakakotahitanga o te pānui i ngā tau, te mārama ki ngā mahere huarere, me te hono atu ki ngā āhuatanga o te kaipuke me te huarahi. Arotahi ki te hau, ngā ngaru (te teitei, te ahunga, me te wā), te pēhanga hau, te ua me te tirohanga, me ngā ia. Whakamahia ngā puna raraunga maha, tirohia ngā whakahōutanga hou, me te manatoko i aua mea mā te tirotiro tika i te moana.
Mā te pānui i ngā raraunga huarere, ehara i te mea ka whakapai ake i te haumaru anake, engari ka pai ake hoki tō whakatere waka, ka whakamaheretia hoki. Ki te hiahia koe, ka taea hoki e au te āwhina i a koe ki te waihanga i tētahi "rārangi arowhai whakamārama huarere" i mua i te whakatere waka, ki te whakarato rānei i tētahi tauira tātari matapae i runga i tētahi huarahi motuhake i Initonīhia.
