Nei chando chena? tichazvidudzira

Mubvunzo sei chando chiri chichena, inozivikanwa vose kubva pauduku. Asi kwete vana vose, uye vakuru vanoziva mhinduro yakarurama, nokuti vamwe chikonzero, muduku snowflake iri chena pane zvitema kana girini. Munhu wose anoziva kuti chando - iri mvura yakagwamba nechando, kana zvirinani chando. Asi sezvo aizi kwakanyatsojeka uye inokwanisa kuparadzira chiedza kuburikidza nawo, nei snowdrifts kuti rakafukidza pasi, kure opaque uye vane nevamwe zvikuru ruvara?

Emakore akapfuura, apo pakanga pasina kugadzira michina kudzidza zvose zvakasikwa urongwa zvakadaro, masayendisiti mutsimba mubvunzo kuti sei chando iri chena. Zvisinei, hapana kupindurwa kuwanikwa. Chete kana yose muitiro yokusika echando kubva pakutanga kusvika pakupedzisira akava pachena, kwave kune zvimwe zvokufungidzira nezve "chena pabutiro."

Zvakangotanga rinotanga chokuti pasi pokudzora kupisa, chiedza chezuva mvura kubva munzizi, madhamu uye makungwa dzikwanise hwemvura uye ichibuda mudenga mumhepo akaturikidzana apo permafrost rikunde. The chiutsi zvinozoita vane ehupfumi mvura, nokuda guru tembiricha kunaka anotanga -oma uye anotendeukira crystals echando. Uyu snowflake, izvo pakupedzisira kuwira pasi. Kazhinji kacho, munzvimbo idzodzo uko unodziyirwa, icicles achawira sezvo akanyorova mvura, akanyauka kunyange mudenga.

Sezvo chando aumbwa, zviri ikozvino pachena, asi vamwe chikonzero, kana inowira pasi, pakarepo inova chena?

The mubvunzo akakodzera, nokuti twemazaya echando uye chokwadi achiri mudenga zvakafanana nokuyerera ehupfumi chiedza kuburikidza nayo, uye kuti chando. Asi hatifaniri kukanganwa chimwe chinhu: pamucheto izvo riri pasi runobva pamakona randomly refracts chezuva, uye havaiti kupinza nayo, uye upfuure. Uye kana twemazaya echando nokuunganidza "chando-chena kwechidzitiro" Mwaranzi yezuva vari refracted ne rimwe snowflake mumwe, kuti apfuure yose butiro. mwaranzi zhinji zvinoratidzwa mumaziso edu, izvo ndokusaka kakawanda, kana uchitarisa chando, tinofanira squint. Zuva iri yakajeka omumwe meso ake kudzivirirwa.

Asi hazvisi chaizvo yakarurama kubvunza mubvunzo sei chando iri chena, nekuti hazvina nguva dzose "kuchena". Saka vanhu kuzviona chete kana zuva mwaranzi kuwira pamusoro payo. Somuenzaniso, zuva ranyura rinogona kupendwa mune pinkish Hue, uye chiedza yeyero rambi ingava jecha chitsvuku, uyewo shongwe ekunze chinhu grayish tint.

Kushandura ruvara kwechando richiri mumhepo akaturikidzana, kana twemazaya echando vachangotanga hwavo "akawira pasi." Somuenzaniso, akasiyana pollens miti nemaruva, guruva yakaoma rinobuda uye remhosva chando specks mu airflows. Kana ichi haana nguva itye chando uye akaponesa duku butiro, zviri vakasungwa kuti noruvara maketeni siyana. In ezvinhu aya, kubvunza sei chando chiri chichena, hakuna kunaka.

Zvisinei, twemazaya echando - haasi chete richibhururuka zvisiri zvenguva dzose pasi icicles, izvo kuti asingazivikanwi zvikonzero, akasarudza kufukidza pasi "chidzitiro chena".

The chikuru ehupfumi echando - ndiko kuti kudzivirira nyika kubva nechando, akafukidza gobvu negumbeze. Hongu, ndizvo noushamwari uye chengeta chirimwa uye ivhu kubva nechando, zvingaita sokuti gangaidzo, asi zviri zvechokwadi. Rine murombo chafariz conductivity, izvo zvinoita kuti kudzora kupisa chaibwinya kubva panyika, uye kuti pave "chafariz pamutsago". Ndosaka yakavakwa igloo vagari kure kuchamhembe. Ice, sechando, zvakanaka akaramba kudziya, nokusika nemamwe mamiriro ezvinhu muupenyu.

Hatifaniri kuona chokwadi chokuti twemazaya echando saizi kunobva okunze panze. Kana kuchitonhora zvakakwana, ice nezvimedu zvidiki, anenge imperceptible. Uye kana zuva riri kupenya uye mhepo inotonhora saka, kukura twemazaya echando inogona kusvika masendimita wandei. Saka, muna 1944, vakawira desyatisantimetrovyh "zvinokosha echando" muMoscow.
