Snow Yintoni? Phi kwaye selikho bekhephu?

ixesha ngalinye ukufika ebusika nekhephu sijamelene ezinye uhlobo ukudubuleka ngokweemvakalelo. ingubo emhlophe azigubungela umzi, amahlathi ashinyeneyo , nooAshera, amasimi ezingapheliyo kunye nemilambo ububanzi, kunye nemithi, ukuba azisongele ku ebengezelayo engaqhelekanga kwi iimpahla elangeni, akayi kukushiya bengenamdla nawuphi na umntwana okanye umntu omdala. Njengoko umntwana sikwazi ukuhlala iiyure yi le window kwaye ubukele nje, ngokucotha osisaqhwithi iqhwa ukubhabha elidlulileyo kwaye ngokuzola ziwe emhlabeni ... Siye bendisoloko ndicinga isakhiwo, ezama ukufumana ezimbini ncam, kodwa Ndamangaliswa ubuhle nokuntsonkotha yale ubungangamsha zobugqi.

Ngekhephu zasebusika njalo ugcwalisa umphefumlo umntwana azive uvuyo nolonwabo ukuyichaza. Ekuhambeni kwexesha, xa umntwana ekhula, imvakalelo kukuthi buthuntu, kodwa endaweni yam ngentliziyo yonke, izingxi, yaye ubuhle be ilele phantsi ezimhlophe komkhusane wendalo. Abantwana badla ukubuza abazali babo: "snow ntoni na?" Abantu abadala ngokuqhelekileyo angasabela monosyllables, esithi ukuba emkhenkceni amanzi. Kweli nqaku siza kuzama uku bana phandle nje kuphela umbuzo wokuba yintoni na kwikhephu, kodwa khangela kwizakhiwo zayo, zozibini inxalenye nenzululwazi, kwaye yi-izibongo.

Yintoni abantu bathi le encyclopedia?

Dictionary Dahl xa ephendula umbuzo wokuba yintoni na kwikhephu, kule ndlela ilandelayo: ukuba umphunga engumkhenkce amanzi, nto leyo kuwa ngohlobo kukubola, madlavu ukusuka emafini; ice okuvakalala ithatha indawo zemvula ebusika. Njengoko ubona, ingcaciso kakhulu omncinane. Umazi-All Wikipedia, laconic kakhulu, ithi ukuba ikhephu - luhlobo imvula entlantlu ziikristale ice encinane. Collegiate Dictionary ingxelo oku kulandelayo: kwikhephu into eqinileyo imvula, nto leyo iqanjwa ice ziikristale, ezahlukeneyo imilo ezahlukeneyo; iqhwa kuthatha uhlobo ezinamacala amacwecwe okanye iinkwenkwezi; idrophu, xa kubanda degrees Celsius. Kubonakala ukuba zonke izichazi-magama neentyilalwazi bathetha kwa into enye, kodwa ayicacanga indlela ezakusebenza ikhephu ntoni na, abancedisi. Kulo mzekelo, jonga iinzululwazi ngqo.

ulwazi zembali

Phi bekhephu? Of oko luqulathe ntoni? Yintoni kwithempritsha yayo? Ezi kunye nezinye imiba emininzi enxulumene nale kwizimanga zendalo, izazinzulu ehlabathini lonke banomdla ixesha elide. Ngoko ke, ngo-1611 i-nabakhwitsi kunye ngeenkwenkwezi Kepler lapapasha imbali yenzululwazi, enomxholo othi, "Ngomhla Imihlubulo ezinamacala amahlanu." Umbhali kokwenzekayo kakhulu wafunda ziikristale ikhephu kunye kalukhuni kakhulu of geometry. Umsebenzi sakhe isiseko lesayensi, njengokuba crystallography theoretical component. Enye owaziwayo-kakuhle ngenkulungwane elinesixhenxe, sezibalo French sobulumko Rene Dekart, nayo inxaxheba ekufundeni iqhwa fomu. Wabhala a 1635 phononongo, yaqukwa kamva emsebenzini "Amava eziwa." Kwixesha elizayo, umbuzo wokuba yintoni na kwikhephu, lithathwa zizazinzulu ehlabathini amaxesha kwihlabathi ezingenakubalwa.

Kwaye ukufunda ingaba le nto izazinzulu mihla?

Namhlanje, nkqu enkulisa abantwana bathi iqhwa ziphenjelelwa ezifana kwihexagons ukuba uyilo lwabo wahlukile kwaye akukho iqhwa efanayo. Ibiya kuthetha ukuba yonke into sele kwaziwa: iqondo lobushushu apho ikhephu linyibilike, into, yaye kakhulu ngakumbi. Kodwa oosonzululwazi baye baphelelwa ngumdla ukuba lo mqondiso hlobo kwaye befunda iinkqubo ukubunjwa iqhwa. Kubonakala ukuba ke zakhiwa ehlabathini ukuze-ebizwa crystallization nuclei, yaye, okubaluleke Okubangel 'umdla kukuba, ukuze elincinane amasuntswana ngothuli, uthuthu, umungu kunye neengxabano.

umgangatho ikhephu, badumisa yi ziimbongi

Ezize - Le isiphumo umdla. Yena ke weva kuphela xa kubanda kakhulu. Ngoko ke, ukuba uya a noko efudumeleyo imini, nekhephu niya kuthi cwaka. Kwaye ngendlela eyahlukileyo iziphatha ngexesha langoku ebusika obubandayo. Abantu baye kudala waphawula: inowuthi lobushushu bekhephu nomoya, kungona ukukrikriza inowuthi. Oosonzululwazi bakwazi ukuqinisekisa ukuba oku kwenzeka ngenxa yokuwela ice crystals ezincinane. Xa Ikhephu amaqondo obushushu uvikivwa, ezi crystals ngakumbi inkumnkum ezilukhuni, ngoko ayikhuphi waziva isandi, ukuqhekezwa phantsi amavili iimoto zethu neenyawo. Ukuba zingaphula onjalo ngumkhenkce, thina bengeva, ngenxa yobukhulu balo encinane. Loo migibe izandi indlebe womntu ayinako ukubamba. Kodwa ke kunye, la ziikristale bayakwazi ukwenza umculo ezizodwa imvelaphi. Oku ezize kakhulu kwaye acule iimbongi kwimisebenzi yabo.

Kutheni ngekhephu okanye imvula?

Umbilo ezinxulumene ezinobunzima disequilibrium (uzinzo) ilifu apho Ziqulethe uluhlu nobuninzi lweziqalelo kwezakhiwo kwaye abe nobukhulu obahlukeneyo. Okukhona efanayo lwesakhiwo eso, uzinze efini apho, yaye, ngokunjalo, okuye ayiyi kunika iidipozithi. Ngaluphi na uhlobo, baya kuwa phantsi ixhomekeka iqondo lobushushu lomoya kwembumba podoblachnom ezikroziswayo, kwakunye ukuphakama kunye nolwakhiwo namafu (ngokomthetho, oko kukuthi oxutyiweyo, oko kukuthi, lenziwa ivuza amanzi amathontsi kwaye ice zamagaqa). Siza baqonde ukuba oku kuthetha. Ewela liphuma efini apho, umxube ukuya kumphezulu planethi edlula podoblachnye mass. Ukuba amaqondo obushushu kulo mzekelo kukuthi ngokwaneleyo phezulu, umkhenkce crystals zinyibilikile senziwa similise eziqhelekileyo imvula eyakhayo lobushushu lehla. Ngamanye amaxesha, kodwa namafu kwendawo, iqhwa kusenokwenzeka ukuba kungabikho xesha ukunyibilika ngokupheleleyo, kulo mzekelo, ikhephu emanzi uwe. Kungenxa yoko le nto off-ixesha lingehla mixed emvula. Ukuba lobushushu podoblachnoy ubunzima lelikhabayo, ngoko ikhephu kulula.

Kutheni maxa wambi ikhephu ehlotyeni kwaye imvula ebusika?

Siye sahlolisisa, xa kuthe ikhephu yintoni ubushushu, kodwa yintoni - imvula. Noko ke, maxa wambi kukho iziganeko ezingaqhelekanga, ezifana njengekhephu ehlotyeni awe, ubusika - imvula. Yintoni uchaza cataclysms ezinjalo? Makhe zama ukuqonda isizathu sokuba kwenzeke oku. Izazinzulu ukubaqononondisa lo mba zokutenxa kwikhondo eliqhelekileyo iinkqubo zophuhliso kwi-atmosfera. Ngenxa yoko, ebusika kwi ezinezinga embindini mass ndifumane umoya ubumanzi-rich kakhulu eshushu ukusuka kumadama elwandle olusemazantsi eshushu. Ngenxa obuhle iqala, leyo azibonakalisa ukunyibilika ikhephu imvula ngohlobo imvula. Ehlotyeni, Singaqaphela eliphikisayo imeko, oko kukuthi ukuya baseMzantsi yamanzi abandayo umoya inkitha evela Arctic. Ngexesha kokurhoxa ngaphambili efudumeleyo kwakhiwa cloudiness enamandla kakhulu, kwimigca candelo iinginginya ezimbini emoyeni amaqondo imvula ezahlukeneyo Luninzi kakhulu. Okokuqala, ekwimo imvula, kunye, e okwalandela Ukupholisa kwaye ephantsi ilifu ngokohlobo ezilula okanye ezimanzi ikhephu. In kwimimandla ekumzantsi, oko akufane kube kunjalo, lo gama iqondo lobushushu kwi emhlabeni iyancumisa.

Snow imiqulu - yintoni na le anomaly?

Kuba okokuqala ukubona esi simanga semvelo, nina isigqibo sokuba lo indalo wezandla zabantu. Enyanisweni, omnye track okanye imiqulu ilenze ngohlobo ngokwayo. Le kunqabile isenzeko zemozulu. adlula ikhephu kudala umoya, ndikhwele logama nje ayithanga pick up ubunzima kunye nobukhulu ikhephu. Ngokuqhelekileyo kula ube zezindlu imilo, kodwa akukho ukuxolelwa. Le nto ibonakala kuphela kwimimandla elinamandla gusty umoya, ukukhanya zimanzi ikhephu kuphela ezivulekileyo kwiindawo. imiqulu ngekhephu ziqengqeleka phezu emathafeni njengoko nemigqomo engenanto. ubukhulu yabo ukufikelela 30 cm ububanzi yaye-30 cm ububanzi. Enyanisweni, xa intsimi ezigqunywe likhephu kunokwenzeka ngexesha elifanayo amakhulu rolls ezahlukeneyo. Ngamnye kubo wemka, azafunyanelwa ndawo - uhlobo lwegama obonisa isikhokelo sendlela siwela. adlula Ikhephu badla lasekwa ngo ingxingwa izaqhwithi ebusika, xa umoya ikhephu onamandla namnandi. Kufuneka ubushushu emoyeni ukusondela zero.

Inkqubo yokwakha adlula nekhephu

Oku kwenzeka ngolu hlobo lulandelayo: umphezulu womhlaba maze azigubungele uqweqwe emhlabeni-ice okanye ikhephu omdala igcwele, kule meko, iqhwa esiwa kunye umaleko engundoqo kufuneka ukubambelela buthathaka. Kuli Umaleko kufuneka elibi lobushushu kunye eliphezulu - HIV (ngaphezudlwana zero degrees). Emva koko fresh snow baya kuba eliphezulu "tack". Iqondo elilelona kuthathwa degrees ezimbini thabatha, nangenxa umaleko ephantsi kunye ezimbini - ngenxa eliphezulu. Gusty umoya kufuneka abe uqina ngaphezulu kwe-12 m / s. roll zakha iqala xa umoya "ukumba" intwana ikhephu. Ngaphezu koko, Amanqatha ezincinane kwakheka, uzibhuqa entsimini phantsi kwempembelelo umoya, ukuzuza ukusuka imitha ngalinye nokukhula umaleko ikhephu emanzi. Xa roll unzima kakhulu, uya kuyeka nayo. Ngoko ke ubukhulu balo ixhomekeke isantya sokuqukuqela umoya.

olunika umdla snow malunga

1. Snowflake 95% emoyeni. Ngenxa yale nto iwela ngokucothayo kakhulu, ngesantya ka-0.9 km / h.

2. Le umbala omhlophe ngekhephu ngenxa yobukho umoya kubume bayo. Ngaloo umtha wokukhanya yabonisa ukususela kwimida ice crystal kunye emoyeni aze asasazeke.

3. kwiimeko eziwela umbala kwekhephu sabhalwa embalini. Ngoko ke, ngowe-1969 e-Switzerland ukugawula black njengekhephu, yaye ngowe-1955 e-California - Green.

4. ezintabeni eziphakamileyo Antarctica kwaye ukukhawulelana ikhephu pink, obomvu, nemisonto emsi, umbala otyheli-mdaka. Oku lula sisidalwa - chlamydomonas ikhephu, leyo ahlala kuyo ikhephu.

5. Xa iqhwa eyele emanzini yenza kakhulu yesandi ophezulu rhoqo. Indlebe lomntu angabi nako ukuyibamba, kodwa zeentlanzi, ukuba ukholelwa izazinzulu, oko akafani kakhulu.

6. Phantsi kweemeko eziqhelekileyo, ikhephu linyibilike kubushushu ka zero degrees Celsius. Noko ke, xa wabetha kwelanga, yaye ngumphunga kwiqondo lobushushu ngezantsi zero, ngaloo ndlela udluliselwe ilulwelo fomu.

7. Xa ebusika, ikhephu ibonisa ukusuka kumphezulu phezulu komhlaba kwi 90% ye imitha yelanga, ngaloo ndlela ethintela ukuba ifudumele.

8. Ngo-1987, e-Fort Into (USA) owabhala flake inkulu ehlabathini. Bayo ububanzi 38 cm.

Ekuphetheni

Apha alungise lo mhlola imozulu, nto leyo ke ngokonga ukuchaza iintyilalwazi kunye nezichazi-magama. Ngoku siyazi lobushushu kuyo ikhephu linyibilike, oko kukuthi, njani, nini yaye kutheni kukho rolls khephu kakhulu oluxhomekeke naloo Herald elihle kunye neqabane kobusika.
