Apo chando anoita? Of kunoti umbwa? Chii tembiricha yaro? Izvi uye zvimwe nyaya zhinji chokuita ichi dzinongoitika chakajairika, masayendisiti munyika vanofarira refu. Saka, muna 1611 n'anga uye zvomuchadenga Kepler yakabudisa bhuku nesayenzi, yaiti, "On the hexagonal flakes." Munyori pragmatic chaizvo anodzidzwa chando crystals pamwe chakazara nehasha pamusoro geometry. basa rake akaumba Achishandisa sainzi zvakadai, sezvo yokungotaura crystallography. Chimwe anozivikanwa mufananidzo nemanomwe remakore, nyanzvi yemasvomhu French uye muzivi Rene Dekart, hwaibatanidzwawo ari kudzidza fomu twemazaya echando. Akanyora nenzira 1635 kudzidza, vakazochinja waibatanidzwa basa "Chiitiko kupfuta." Mune ramangwana, mubvunzo zviri chando, runoonekwa masayendisiti munyika yose kasingaperi.

Uye kudzidza kana chiitiko ichi masayendisiti ano?

Nhasi, kunyange kukireshi vana vanoti twemazaya echando zvinoumbwa akafanana hexagons kuti zvakagadzirwa kwavo kunoshamisa uye kuti hapana akafanana twemazaya echando. Zvaizoratidza sokuti zvinhu zvose nechakare: tembiricha panguva iyo chando inonyunguduka, pane zvinhu, uye zvakawanda. Asi masayendisiti haana kurasa mubereko kuti chishamiso ichi hunhu uye vachiri kudzidza dzinotsanagura inotungamirwa twemazaya echando. Zvakaratidza kuti vari achiumbwa kumativi vanonzi crystallisation nuclei, uye, kupfuura Sezvineiwo, vangava nezvimedu miniti muguruva, chin'ai, mukume, uye kunyange spores.

chando quality, yaakakudza vadetembi

Creaking - Izvi inonakidza kushanda. Iye anogona kunzwika chete zvikuru kuchitonhora. Saka, kana uchazomukira pazera kudziya zuva, chando uchava chimumumu. Uye zvakasiyana nayo haazvibati panguva ino yechando inotonhora. Vanhu refu wakacherechedza: rezasi chando uye mhepo tembiricha, dzakanga kukwirira kwenzwi svisvidza. Masayendisiti vaigona kuziva kuti izvi zvinoitika pamusana kupwanya nemaziso echando crystals. Kana chando tembiricha iri akatura, crystals izvi kuva pfava uye zvakaoma, saka ivo emit mumwe creaking ruzha, nokuputsa pasi mavhiri motokari uye netsoka dzedu. Kana zvamunopwanya rimwe sekristaro yakadaro, isu havanzwi, nokuti ayo duku ukuru. Kwakadaro dzisinganyatsooneki rinoroverera munhu nzeve haisi kukwanisa kubata. Asi pamwe chete, kuti crystals vanokwanisa kuumba rakasiyana Mumhanzi. Izvi chaizvo creaking uye nziyo vadetembi mumabasa avo.

Nei chando kana mvura?

Precipitation chokuita disequilibrium (kugadzikana) gore makore acho ane muzvizhinji ine zvinhu zvakasiyana hurongwa uye hukuru. The zvakawanda dzakafanana nemamiriro, akatsiga zvikuru mugore, uye, naizvozvovo, kwenguva refu harizokudzoreri deposits. In chii chimiro vanosvika pasi, kunoenderana tembiricha dzekudenga gobvu iri podoblachnom layer uyewo pakakwirira uye maumbirwo yegore (kazhinji yakavhenganiswa, i.e. unotora two chilled mvura mumate uye chando crystals). Tichanzwisisa kuti ichi chinoreva. Achiwa kubva mugore, musanganiswa kurutivi pemvura nyika ichipfuura podoblachnye guru. Kana tembiricha hazvisi zvakakwana yakakwirira, chando crystals kunyunguduka tinoshandurirwa kwomuzvarirwo mvura zvakanaka tembiricha madonhwe. Dzimwe nguva, akapa pasi kukwira makore, twemazaya echando varege kuva nguva itye zvachose, muchiitiko ichi, akanyorova chando inowa. Ndokusaka muna kure-mwaka anogona kuwira yakavhenganiswa kunayisa. Kana podoblachnoy gobvu tembiricha iri negative zvino chando zviri nyore.

Nei dzimwe nguva snows muzhizha uye mvura munguva yechando?

Takurukura, pane chii tembiricha iri snowing, asi pane chii - mvura. Zvisinei, dzimwe nguva pane zviitiko zvinoshamisa, zvakadai zhizha chando anogona kuwira, uye chando - kuti mvura. Chii anotsanangura cataclysms dzakadaro? Ngatiedzei kunzwisisa nei zvadai. Masayendisiti anotsanangura Fani iyi yakatsauka kubva chakaipa nzira chiitiko pezvakaitwa mumhepo. Saka, munguva yechando pakati latitudes gobvu vanokwanisa chaizvo inodziya unyoro-mupfumi mhepo chaifamba kubva madziva nechokumaodzanyemba inodziya makungwa. Somugumisiro yacho nyungudika kunotanga, iyo anozviratidza mu kunyunguduka chando uye kunayisa muchimiro mvura. Muchirimo, tinogona kucherechedza pakatarisana ezvinhu, kuti riri zasi anogona hombodo chando mhepo makore kubva kweArctic. Munguva shure pamusoro inodziya mberi aumba cloudiness simba kwazvo, ari chikamu akarongwa maviri mhepo zvavo nedzimwe kunayisa kutonhora zvakawanda chaizvo. Chokutanga, muchimiro mvura, uye zvakare, panguva nekutambira kutonhora uye akatipa gore pasi muchimiro nyore kana nyoro chando. Kumaodzanyemba kunzvimbo, ndiyo nyaya kashoma, apo pose tembiricha iri pasi inoramba zvakanaka.

Snow mabhanzi - chii anomaly ichi?

Kokutanga kuona chishamiso ichi zvakasikwa, kusarudza kuti ichi ndicho kusikwa maoko evanhu. Kutaura zvazviri, kwakadaro njanji kana mabhanzi dzinokanganisa chisikigo pachacho. Izvi haiwanzowaniki Meteorological chinoshamisa. Sinou mabhanzi anosika mhepo, kuchovha chando chero haana kunhonga yairema uye kukura. Kazhinji zvidimbu izvi vane cylindrical chimiro, asi pane kusaina. Fani iyi inogona kuchengetwa chete kumatunhu ane simba gusty mhepo, chiedza nyoro chando uye chete akazaruka munzvimbo. Chando mabhanzi vagokungurusa pamusoro inowanzorimwa chaanacho emiti. saizi yavo inogona kusvika masendimita 30 dhayamita uye 30 masendimita pahupamhi. Kutaura zvazviri, pane munda nesinou inogona kuitika panguva imwe chete nemazana yoga mabhanzi. Mumwe nomumwe wavo vakasiya zvikasawanirwa - kubva njanji imwe mhando kuti inoratidza trajectory yacho zvaiyambuka nzira. Snow mabhanzi zvinowanzotaurwa kuumbwa panguva kwemutemo semadutu yechando, kana mhepo yakasimba uye yakachena chando. Mhepo tembiricha anofanira pedyo razero.

Muitiro nokuumba mabhanzi chando

Izvi zvinoitika sezvinotevera: Nyika pamusoro inofanira kufukidzwa pasi paiva chando kana arongedza chando yekare, muchiitiko ichi, akawira chando pamwe runotikurudzira rukoko vane murombo adhesion. Rezasi rukoko inofanira kuva akaipa tembiricha uye okumusoro - yakanaka (zvishoma pamusoro razero madhigirii). Zvadaro kutsva chando achava mukuru "chipini". The tembiricha optimum runoonekwa kuti kubvisa madhigirii maviri, uye nokuda rezasi rukoko ndinoiitawo miviri - nokuti rokumusoro. Gusty mhepo inofanira kuva velocity kupfuura 12 m / s. rwakapetwa achiumba kunotanga apo mhepo "kuchera" chimedu chando. Uyezve, nemavhinga duku dziri kuumbwa achifinyamisa munda achifuridzirwa mhepo, kuwana kubva mita rimwe kukura paiva nyoro echando. Kana rugwaro chinokuremera, zvichava kurega. Saka kuti saizi yayo kunobva mhepo chekubuda unodiwa.
