La i-meteor shower, noma i-meteor shower, yinto yezinkanyezi yobuhle obubodwa okuthi, ngenhlanhla, singajabulela okuningi ngokubuka isibhakabhaka. Kepha yakhiwa kanjani? Futhi, okubaluleke kakhulu, uma kungenzeka, Iziphi izinsuku ozibonayo?
Uma unentshisekelo yokwazi konke mayelana nokugeza kwesibhakabhaka, ungayeki ukufunda.
Yini iMeteor Shower?
Esikhaleni sangaphandle kunezinkanyezi ezinomsila, ama-meteorite, ama-asteroyidi, nezinto ezahlukahlukene zezinkanyezi okuthi uma usondela ngaphakathi kuSolar System, umoya ovela enkosini yenkosi ubangele ukuthi indawo isebenze; Ngakho-ke, amagesi nezinto ezikuqambayo kuphuma kuye emkhathini ukuze kwakheke umfudlana noma indandatho yezinhlayiya eyaziwa ngokuthi yisixhwanguxhaka semeteor. Uma kuyi-meteor, lesi sihlava ngokuvamile sibizwa ngokuthi inkanyezi yokudubula.
Umphumela wokukhanya ukhiqizwa yi-ionization yomkhathi owenziwe yizinhlayiyana. Iningi lama-meteor ahlangana nomoya womhlaba mancane kakhulu, afana nezinhlamvu zesihlabathi, ngakho-ke lapho ehla ngo-80-100km ukuphakama umphumela awuhlaba umxhwele kakhulu; Kodwa-ke, kukhona amanye, ama-fireballs, ahlakazeka endaweni ephakeme ye-13-50km eshiya ukukhanya okumangazayo kokukhanya.
Ungazibona kanjani izinkanyezi zokudubula?
Le nto inezici ezintathu ezenza ihluke: i-radiant, inkomba yabantu kanye ne-Zenital Hourly Rate noma i-THZ.
- Okukhazimulayo: yiphuzu lapho ama-meteors eshawa emisa ukuphuma khona. Kukalwa ngokuxhumanisa i-Alpha, okungukukhuphuka okulungile noma i-AR, ne-Delta, okungukuncipha noma i-Ddec.
- Inkomba yabantu: isilinganiso sokukhanya phakathi kwamalungu eqhubu elifanayo le-meteor.
- Isilinganiso Sehora Ngehora: isibalo esiphezulu sama-meteor abaliwe umuntu obonayo angabona uma isibhakabhaka sicacile, iNyanga ibingagcwele, futhi kungekho ukungcola okuncane.

Okubalulekile:
- Lluvia: ikhombisa igama nesifinyezo semvula.
- Isikhathi somsebenzi: yizinsuku lapho kusebenza khona.
- Isikhulu:
- Usuku: usuku lapho kungabonakala inani elikhulu lama-meteor.
- Ilanga: I-Solar Longitude. Kuyisilinganiso sesimo seMhlaba ekuzungezeni kwawo.
- Okukhazimulayo: izixhumanisi zesimo sokukhazimula kwemvula. α yi-Right Ascension, δ yi-Declination.
- v akupheli: isivinini esifinyelelwa yizimbumbulu lapho zingena emkhathini. Inikezwa nge-km / s.
- r: yinkomba yabantu. Uma i-r ingaphezu kuka-3.0, kusho ukuthi ibuthakathaka kune-average; esikhundleni salokho uma kungu-2.0 kuye ku-2.5 kuzobe kukhanya ngokwengeziwe.
- THZ: isilinganiso sehora le-Zenital. Uma iphezulu, I-THZE iyasetshenziswa. Uma iyahlukahluka, ikhombisa »var».
Ungayibona kanjani imvula yamameteor?
Izinkanyezi zokudubula zingabonakala ngeso lenyama, inqobo nje uma isibhakabhaka sicwathile futhi neNyanga ingagcwele, kodwa ngeshwa ngokuthuthuka kwamadolobha kuya kuba nzima ukuwajabulela ngokugcwele. Ngakho-ke, Uma ufuna ukucabanga ngobuhle bayo, kufanele ubaleke ngangokunokwenzeka ezindaweni ezisemadolobheni.
Thatha ithuba lokuhamba nabathandekayo bakho uye emaphandleni noma ezintabeni ukuyobabona. Impela uzoba nesikhathi esihle 🙂.
Imvula enkulu yama-meteor nezinsuku abazibonayo
Njengoba sibonile, kunezinqwaba zezinkanyezi zokudubula ezingabonakala unyaka wonke, kepha ezaziwa kakhulu yilezi ezilandelayo:
- Ama-Quadrantids: isikhathi salo somsebenzi sisukela kuJanuwari 1 kuye ku-5, kanti ubukhulu baso kube ngoJanuwari 3. Ingenye yezimvula ezinamandla kakhulu onyakeni, neZenith Rate Hourly engu-120 meteors / h.
- Lyrid: isikhathi salo somsebenzi sanda phakathi kuka-Ephreli 16 no-25, kanti ubukhulu baso bungu-22.
- Ama-Perseids: ibizwa nangokuthi Izinyembezi ZaseSan Lorenzo. Isikhathi salo somsebenzi sisukela kuJulayi 17 kuya ku-Agasti 24, kanti ubukhulu baso buphakathi kuka-11 no-13. I-Zenith Rate Hourly ingu-100 meteors / h.
- Ama-Draconids: kwesinye isikhathi kuthiwa yiGiacobinids. Bayimvula isikhathi sabo somsebenzi esiqondakalayo kusuka ngo-Okthoba 6 kuya ku-10, sifinyelela esiphezulu ku-8. SineZenith Rate Rate eguquguqukayo.
- Ama-Orionids: ziyimvula yomsebenzi olinganiselayo isikhathi saso somsebenzi esisukela ku-Okthoba 2 kuye ku-Novemba 7, sifinyelela phezulu ngo-Okthoba 21. Isilinganiso sayo sehora leZenith ngama-meteor angama-23 ngehora.
- Leonidas: bayimvula isikhathi sabo somsebenzi esisukela kuNovemba 15 kuya ku-21, futhi sifinyelela kwisilinganiso somsebenzi njalo eminyakeni engama-33. Izinga lalo leZenith ngehora lingamamitha angu-20 ngehora.
- AmaGeminids: ingenye yezimvula ezinomsebenzi omkhulu kakhulu. Banesikhathi somsebenzi esukela kuDisemba 7 kuya ku-17, kanti usuku olufinyelela phezulu ngu-13. Izinga leZenith ngehora ngamamitha angu-120 ngehora.
Ukudubula izithombe zezinkanyezi nevidiyo
Izithombe
Ukuqeda, sikushiya nalezi zithombe ezinhle zemvula ebonwe ezingxenyeni ezihlukene zomhlaba.
