N'chifukwa chiyani chipale chofewa? ife tinena

N'chifukwa chiyani chisanu ndi woyera, ndi bwino kuti aliyense kuyambira ali mwana. Koma si ana onse, ndi akulu amene akudziwa yankho lolondola, chifukwa ena, snowflake pang'ono ndi zoyera koposa buluu kapena zobiriwira. Aliyense akudziwa kuti chisanu - ndi madzi achisanu, kapena m'malo ayezi. Koma ngati ayezi chimaonekera ndipo angathe kupatsira kuwala mu izo, chifukwa chisanu chosuntha kuti anaphimba pansi, kutali opaque ndi ndifilimu chosiyana kwambiri?

Kale, pamene panalibe chitukuko amenewa matekinoloje kuphunzira njira zonse zachilengedwe, asayansi akhala akulimbana ndi funso la chifukwa chisanu ndi woyera. Komabe, palibe yankho linapezeka. Only pamene dongosolo lonse chilengedwe cha chisanu kuyambira chiyambi mpaka mapeto zinadziwika, pakhala ena nkhambakamwa za "chivundikiro woyera."

Izo zonse akuyamba ndi chakuti mchikakamizo cha kutentha, dzuwa madzi m'mitsinje, nyanja ndi nyanja n'kukhala nthunzi ndipo kukudza mkulu mu zigawo mumlengalenga kumene Madzi oundana ponseponse. The nthunzi nayenso ndi katundu wa madzi, chifukwa cha lalikulu zoipa kutentha umayamba amaundana ndi kutembenukira kwa timibulu ayezi. Izi ndi snowflake, zomwe pamapeto pake wokonzeka kugwa pansi. Nthawi zambiri, mu malo amenewo kumene ndi ofunda, icicles kugwa mvula madzi okhaokha, anasungunuka ngakhale mu mlengalenga.

Monga chisanu aumbike, tsopano bwino, koma pazifukwa zina, pamene ikagwa, iye mwadzidzidzi woyera?

Funso zogwirizana, chifukwa zidutswa za chipale chofeŵa ndi choonadi akadali mu mlengalenga chimodzimodzi otaya katundu wa kuwala, ndipo kuti ayezi. Koma sitiyenera kuiwala chinthu chimodzi: nsonga ya mandala ili pansi pa ngodya wachisokonezo kuti mosintha refracts dzuwa, ndipo iwo sakudziwa kuyamwa izo, ndi kupatsira. Ndipo pamene zidutswa za chipale chofeŵa kusonkhanitsa mu "moyera-chophimba," dzuŵa ndi refracted ndi snowflake limodzi ndi mzake, kudutsa chivundikiro lonse. cheza ambiri zikugwirizananso ndi maso athu, nchifukwa chake zambiri, pamene inu muyang'ana pa chisanu, tili squint. Dzuwa lawala kwambiri amaonera maso ake mosadziteteza.

Koma si zoonadi kufunsa funso la chifukwa chisanu ndi woyera, chifukwa si nthawi zonse "woyera". Choncho anthu kuwona izo zokha pamene dzuwa cheza kugwa pa izo. Mwachitsanzo, dzuwa litalowa akhoza utoto azioneka pinkish, ndi kuunika kwa nyali chikasu akhoza kukhala pang'ono mchenga yofiira, komanso mu nyengo mitambo ndi grayish kulocha.

Kusintha mtundu wa chisanu akadali mu zigawo mpweya, pamene zidutswa za chipale chofeŵa Mukungoyamba awo "kugwa lapansi." Mwachitsanzo, pollens osiyana mitengo ndi maluwa, dothi auka youma dziko ndi likukwaniritsa specks chisanu airflows. Ngati uyu alibe nthawi amasungunulira chipale chofewa ndi opulumutsidwa chivundikiro laling'ono, wamangidwa kukhala mtundu wa mithunzi zosiyanasiyana. Mu zinthu izi, kufunsa chifukwa chisanu ndi woyera, ndi zosayenera.

Komabe, zidutswa za chipale chofeŵa - Osangopereka zouluka erratically pansi icicles, amene pa zifukwa zosadziwika, anaganiza kuphimba nthaka "woyera chophimba".

The katundu waukulu wa chisanu - ichi ndi kuteteza dziko lapansi kuzizira, yokutidwa ndi bulangeti wandiweyani. Inde, ndi ofunda ndi kusunga mbewu ndi nthaka kuzizira, zingatanthauze paradoxical, koma izo nzoona. Iwo ali osauka matenthedwe madutsidwe, amene amalola iye kuletsa kutentha panamveka ku dziko lapansi, ndi kulenga "matenthedwe khushoni". Nzosadabwitsa kuti anamanga igloo okhala akutali. Ice, ngati chipale chofewa, yosamalika ofunda, polenga zinthu mwapadera moyo.

Sitiyenera kuiwala kuti zidutswa za chipale chofeŵa kukula zimadalira nyengo kunja. Ngati ndi ozizira mokwanira, particles ayezi ang'ono, pafupifupi imperceptible. Ndipo ngati dzuwa likuwala ndi mpweya ndi wozizira, kukula kwa zidutswa za chipale chofeŵa kungakhale kwa masentimita angapo. Choncho, mu 1944, anagwa desyatisantimetrovyh "yokha ayezi" mu Moscow.
