Ukuvelela - it ... prominences kwi iLanga

Phantsi umsebenzi solar ukuthini wokuhlangana nesenzeko ezidlulayo, ezo dynamically, kunye ezahlukene esebenzayo evela emoyeni elanga. Enye indlela okubonakala ke imbonakalo yomsebenzi yalo mhlaba otsalayo le imicu ezithile umoya solar, oko kukuthi - ngokobuninzi plasma. Xa sibonakale ngohlangothi disk ilanga, zibizwa ngokuba prominences.

Prominences - ntoni na?

Sisihlandlo sokuqala yokuba ngexesha komnyama iyonke solar waphawula ukubonakala kwiziseko ezingaqhelekanga, wabonakala 1185, yaye isifundo eneenkcukacha kubo kwaqala 1842. Kamva babizwa prominences (protubero), nto leyo yaguqulelwa isuka kwisiLatini lithetha "enyukayo."

Namhlanje, enkosi izifundo ezininzi, kwakusazeka ukuba ukuvelela - Ukwakheka plasma elanga ukuba ubukhulu. Ezi ezikhutshwayo ezinkulu bavuke ngaphezu komhlaba kwelanga yi imigca amandla lentsimi yayo Imagnethi yomhlaba kunye zigcinwa khona ngenxa kuyo ngexesha elithile. Abanye babo basenokuba 'bambelela' kwisithuba solar ngamanye amaxesha ukuya kwiinyanga eziliqela, phantse akukho tshintsho ngohlobo lwabo lokuqala.

Prominences enyanisweni

Ngaphandle kwento yokuba ukufunda ngokuseka angaqhelekanga inzululwazi iye ibe lixesha elide, theory licace gca, liphelele ukucacisa ngeyantlukwano yabo kunye nesenzeko ezahlukeneyo ezinxulumene, hayi wayekunye nabo. Enyanisweni prominences indalo - kuba ifayibha mnyama, ibonakale ngokucacileyo chromosphere kwelanga. isakhiwo sabo luthe abandayo ngaphezu plasma ejikelezileyo, kunye nokwakheka eekhemikhali iseti lweziqalelo esihambelanayo kubo zakha umaleko. Noko ke, imeko yabo yangaphakathi emzimbeni kangangokuba uluhlu ezinye prominences oversaturated imigca hydrogen, kunye nezinye - kunye nesinyithi ezahlukeneyo. Ubude ubukho babo ibonisa ukuba nengqwebo yawo okugcinwe zemagnethi.

Njengoko prominences zenzeke?

prominences Solar kuvela ezakhiwe njengoko eqaqambileyo ngokwandisa ecaleni kungqameko disk elanga. Ebonakala imvelaphi wakhe, ukuba abe umbala emnyama, apho kungenxa ngaphantsi kwe indawo yabo, iqondo lobushushu plasma.

Ngokuchasene yangasemva corona ukuvelela kushushu - kwintsunguzi nengqele ngokwakha. Ukunyuka phezu kwelanga, oko engagqibekanga licwangcisa nengqwebo yawo, yaye emva koko wehla inyamalala. Ezinye zazo ezisegumbini isithsaba kangangeenyanga, abanye, ehamba ngesantya esiphezulu, musa shwaka iiveki. iikopi Abangatshatanga ukuba isantya enkulu, ngesiquphe zisenokuqhushumba.

Yintoni ubungakanani izinto prominences?

Protuberances elangeni hits imilinganiso yalo angaqhelekanga. abameli imifuziselo ezi zakhiwo ifikelele kubude ukuya ku-40 ophosa, ngoxa ububanzi yabo ibe malunga 200 ophosa. Kukho kwakhona ezikhutshwayo ezinjalo, ukuphakama leyo 800 ophosa. Ngokuphindaphindiweyo izazinzulu abhalwe intshatsheli ezinjalo, ubukhulu amakhulu eekhilomitha 3 million. Kuqhuma omnye prominences elikhulu enjalo, leyo wadubula phezulu, zongameleyo i intsimbi yehashe, yake yabonakala kwisiphekepheke iiyure ezingama-30 ngo-Agasti 2010.

Zeziphi prominences?

Ngokuseka kunokuba kakhulu ezahlukahlukeneyo. Imbonakalo kunye nesantya prominences kwi Ilanga zihlukaniswe:

• umoya, esibonakala intshukumo kade kwaye ungatshintsha phantse isiphumo imperceptible kwimilo, abe iiveki ezimbalwa okanye iinyanga;
• esebenzayo, izinto ezo luphawulwa flow ukuzila kwaye ithatha nje imizuzu embalwa amashumi iiyure;
• sisaqhubeka (coronal) idla kwenzeka ngohlobo amafu ezincinane, nto leyo ekugqibeleni bahlanganisane ukuze ilifu enye enkulu leyo ikhona iiyure eziliqela;
• Eruptive (okanye ukuthatha off) zifana imithombo enkulu ukuba qhuma ngokukhawuleza kakhulu uze utshintshe isimo sayo, yaye emva koko ngokukhawuleza shwaka.

Kuxhomekeka ukuma kwabo, kwakunye indlela apho izinto ngokwayo ihamba, ukuba zahlulwa ngokwendidi ezintathu:

1. WeMfundo ngokohlobo umsi okanye amafu jet ekwaziyo kokonyuka isantya ukuya ukuphakama enkulu.
2. Protuberances ngohlobo iinqwelo-moya egosogoso kunye neeyunithi eqala zize ziphele kumphezulu elanga. Njengomgaqo, phezulu kunye imigca zibuthe, ngokugabadelayo aqala ukuncipha.
3. Formation of umthi omkhulu iwindow okanye ityholwana. Ukwakheka impahla yabo ukuhamba ngokwazo, ngexesha ukuba uqina ongadluli emashumini ezimbalwa km / s.

Njani ukuba agcine prominences?

Ukuvelela - kubonisa lomsebenzi elanga. Wati kunokuba ngexesha Ilanga solar, nangona kakhulu inqabile. Yiloo nto izazinzulu ziye kwakhiwa izixhobo spectroscopic ukuba lokuphinda eclipse ngumntu. Ezi iiteleskopu zenziwe iintlobo ezikhethekileyo ngeglasi, lube microbubbles ziquka disc omnyama, leyo amile inyanga. Ngexesha lokujongwa iLanga, wada umba phezu kwayo, nto leyo izixhobo babone ukukhanya okuvela kuphela kwesithsaba saso.

Phambi kwamehlo abazibonayo umfanekiso emnandi - prominences wezomdaniso ilanga. Beyond ngohlangothi inyanga zokwexeshana ngokucacileyo uqikelelo ezibonakalayo imilo esimbaxa umbala oqaqambileyo epinki, ezifana amadangatye okanye amafu enkulu babalekayo umphantsi nomphezulu lwe disk elanga.

Kwisithuba sonyaka-11 incopho msebenzi solar inokubonakalisa protuberances arc-ezimile coronal. Yinto kunqabile ubuhle non-ingadluliselwa - ukuyilwa kwento ilifu elikhulu, ukusuka apho Iikona umlambo phantsi kuvela kwi corona solar ngaphezu kwayo chromosphere.

Ukuze izazi elide wahlala nesenzeko angaziwayo kwenzeka corona elanga. Ukuvelela ... Ilizwi linxulunyaniswa imfihlelo abagcina nkwenkwezi ebizwa ngokuba ilanga. Kwaye ngoku, ngenxa satellites nezikhululo isithuba, uninzi ezi mfihlelo ibonakalalisiwe.

Uluntu luya kwenza izinto ezifunyaniswe ezininzi kakhulu endaweni yonke unexplored kunye wezijikelezi-langa.
