Chisanu ndi chiyani? Kodi chisanu?

Chitsanzo kusintha nyengo m'chilengedwe lirilonse miyezi itatu - mu kasupe wa, chilimwe, m'dzinja ndi yozizira. Mu dziko lathu, chaka chilichonse pakati pa December ndi February mwachangu chisano - chimodzi cha zizindikiro cha isanayambike yozizira. Kodi aliyense mukudziwa momwe chisanu ndi? Ndipo kodi zodabwitsazi zachilengedwe zonse? Ife tikupeza m'nkhani ino!

ndi chisanu Kodi

Chipale - Umenewu ndi wa mpweya umene umaphatikizapo timibulu ka ayezi. Asayansi amanena kuti Ponseponse mpweya kugwa mwachindunji pansi. Komanso, chisanu - ichi ndi chimodzi mwa zinthu zofunika kwambiri pa dzinja, kubwera mu imodzi kapena dera lina la dziko lapansi.

Zachikhalire ndi impermanence wa chisanu

Ndikuyankhula zomwe ndi matalala, osanenapo kulimbikitsa kwake. Common - otsika kutentha, pakalibe chisanu. Mfundo imeneyi ndi m'chigulugulu pankhani otchedwa yozizira nyengo yodziwika ndi kukhalapo nthawi zonse chisanu pansi, lomwe lili pa nthawi yonse ya kalendala yozizira.

Oddly okwanira, koma khama la chisanu - vacillates. Osachepera m'madera ena a dziko. Modabwitsa, okhala m'madera ofunda (Africa, ku Arabiya, Madagascar, America South), dziko silikudziwa chimene Chipale. Ndipo onse chifukwa cha chodabwitsa nyengo m'madera ofunda a dziko kulibe kapena pali kamodzi mu zaka 10-20.

Zinthu kuli chisanu

Ndi chodabwitsa, koma chikhalidwe nyengo ya chodabwitsa akhoza unalipo m'mikhalidwe awiri:

• ndi kuchuluka kwa chinyezi;
• otsika kutentha (m'munsimu 0 digiri Celsius).

Synoptists anaona kuti snowfalls wambiri zimachitika mwachibadwa pa kutentha ndi mkulu kwa madigiri -9 Celsius kapena kuposerapo. Amanena izi chakuti apamwamba kutentha, m'pamenenso lili nthunzi. Kuti nthunzi ndi lofunikira "maziko" a chisanu.

Pakuti anthu chidwi ndi zimene chisanu, tiona kuti uthunthu wa zili madzi ndi waukulu ndithu: ngati inu atembenuke mfundo izi mu manambala, inu mumatenga masentimita 0.1 5 madzi mu 10 centimeter wosanjikiza wa chisanu kwala pansi. Chofunika kwambiri apa ndi mphepo liwiro, dongosolo la galasi la chisanu, kutentha, etc.

Kodi dongosolo la chisanu

Mbali yaikulu ya zinthu Chipale, indedi, snowflake. Ngakhale kukula kwake tizilembo timeneti (avareji pafupifupi 4 millimeters), ndi snowflake ali ndi chosokonekera modziwika wangwiro. Koma akatswiri kudabwa ayi, koma pagona! Iwo amaganiza izo ziri zachirendo kuti osati chisanu pa dongosolo, ndi amene zosiyanasiyana akalumikidzidwa chodabwitsa ndi dongosolo kupanga yokhotakhota zidutswa za chipale chofeŵa nkhope.

Ngati tikulingalira zidutswa za chipale chofeŵa ku mfundo imeneyi, tikhoza kunena motsimikiza kuti ali onse wapadera. Ndi mtundu wa chodabwitsa ka dziko! Zakhala chatsimikiziridwirapo mwasayansi kuti izi matalala "njerwa" kukhala enieni kwambiri zojambula mizere, amene ndi hexagon. Mu zidutswa za chipale chofeŵa chodabwitsa mawonekedwe amakhudza mlingo chinyezi ndipo, ndithudi, yozungulira mpweya kutentha.

Kuti tipeze snowflake mwangwiro yosalala, mamolekyulu madzi ayenera amaundana ndi kutembenukira kwa timibulu ayezi. Kukhala moyandikana pafupi wina ndi mnzake, iwo azunguliridwa, ngati unyolo, ndipo amaundana pa mfundo imodzi, kutembenukira mu mawonekedwe zojambula. Pa nthawi ino palibe chikaiko pakati pa asayansi mmene snowflake ndi mndandanda wa mamolekyulu achisanu madzi anakonza mu unyolo.

N'chifukwa chiyani tiyenera chisanu

Chipale ali katundu zingapo zofunika akutsutsana kuwononga chilengedwe. Tiyeni tione iwo mwatsatanetsatane.

1. Chipale zimatenga phokoso ndipo kumachepetsa mmene phokoso osiyanasiyana kunja kwa malo ozungulira. Izi zimachitika chifukwa pali thovu pakati zidutswa za chipale chofeŵa ndi mpweya, zofooketsa kugwedera kunja. Mwa njira, ichi anafotokoza achilendo crunching chisanu poyenda mu nyengo yozizira koopsa. Creaking kufalitsa timibulu mazira, akusisita wina ndi mzake pamene cholizira. Kuchokera pa zimenezi deform ndi kung'amba.
2. Kodi mtundu ndi chisanu? Ambiri, chikhalidwe cha icho chiri yekha woyera. Chimam'thandiza kusonyeza dzuwa, kuchepetsa kutentha yozungulira. Koma chifukwa kuchepetsa izo? Yozizira idali nyengo yozizira, osati m'firiji pamtunda! M'madera ambiri adziko lapansi ndi zodabwitsa popanda yozizira chisanu ndi kutentha otsika.
3. Ntchito ina yofunika kwambiri chisanu achibadwa a moyo - ndi mtundu wa chitetezo wa nyama ndi zomera ku mavuto kunja. chakuti chisanu chivundikiro amasunga kutentha kwa dziko anapeza pa dzinja, sanafe kupereka nyama zazing'ono zomera zambiri, ngakhale chisanu zovuta. Ngati inu mukumbukira, kodi chisanu (anawona pamwamba), n'zosavuta ndikuganiza kuti amalenga malo ena chinyezi zofunika ndi thupi pa kasupe kudzutsidwa.
