N'chifukwa chiyani mvula - Kodi amachokera?

Anthu ambiri amaganiza za izo, chifukwa ndi mvula kapena chipale chofewa. Amabwera amapita, koma nyengo ndi zoipa, oipayo amawononganso wosangalala. Koma ndi chidwi zachilengedwe kuti sizingawononge kufufuza zonse, chifukwa, kukhala makolo, anthu zambiri kumva funso limeneli yooneka ngati yosavuta: "N'chifukwa chiyani mvula kapena kuwala?". Nyenyeswa kwenikweni kufotokoza zinthu zonse, koma mwana isanu ndi umodzi kapena chaka chimodzi amatha kuona malongosoledwe kwambiri. Choncho ndi bwino kudziwa yankho la funso limene mwana amafunsa mu chikumbutso cha ambulera ndi nyengo yoipa.

sukulu umagwirira zochita zawo anthu ambiri kudziwa kuti madzi kulibe mu madera osiyanasiyana a loitanirana: olimba, madzi ndi gaseous. Komanso, kuchokera madzi ndi mkhalidwe gaseous, icho chimapita pafupifupi nthawi zonse ndi zambiri tima apamwamba kutentha kwake. Mukasiya matope a madzi pa tebulo, patapita kanthawi izo uphwetsa - asanduke nthunzi. Mofananamo, ukuphwera ku mitsinje, nyanja, masamba a zomera, dothi - kuchokera pamalo alionse. Iye anabwerera ku mitsinje mobisa ndi nyanja kuti kudyetsa mvula Panapita. Kotero izi madzi ukuphwera, kwasanduka nthunzi.

Koma mu chikhalidwe chilichonse ndi kugwira onse pa chivundikiro cha poto ndi otentha madzi ndi mkulu mu troposphere, kumene kutentha mpweya n'chosiyana kwambiri kuti anaona pafupi nthaka, condensation, mwachitsanzo dontho la madzi. Pamene iwo anakhala wolemera kwambiri, ndiye iwo kudziunjikira kwambiri, anapanga mitambo yamvula ndipo kenako kugwa madontho nthaka ndi yokoka - mvula akubwera! Madzi amatenga m'mitsinje, mitsinje, kenako zatsalira zake dera limodzi mwa nyanja. Izo zonse akuyamba kachiwiri. Kumene, ndondomeko anafotokoza penapake chosavuta, koma popanda zosiyidwa iliyonse yaikulu.

chodabwitsa Ichi chikudziwika ngati bwalo kapena mmene kanyamaka wa madzi mu chirengedwe. Komabe, yotsirizira akuti penapake lolakwika, monga whirlpool ndi zafala chodabwitsa wina amene alibe poyerekezera ndi mpweya.

nkhani izi zonse pang'ono akulongosola chifukwa mvula. Nthawi zina, m'malo ndi chisano, ndi madzi m'malovu amaundana ndi kukhala zidutswa za chipale chofeŵa - timibulu ayezi. Grad - kwambiri chidwi chodabwitsa, kumachitika pamene condensate, mwachitsanzo madzi m'malovu adzawombana ndi mpweya ozizira kwambiri, pamene ena akhoza zii koma osati kukhala zidutswa za chipale chofeŵa ndi kuwasandutsa matalala. chachikulu matalala angagwe ngati mtambo ali updraft amphamvu, amene salola mpweya kugwa ndithu nthawi yaitali. Pamene ozizira mtambo collides ndi mpweya otentha, mkuntho akuyamba, kugwa matalala. zodabwitsazi Komabe, si lofanana ndi kuzizira mvula, pellets matalala kapena Matalala Osungunuka - zosiyana kwambiri.

Pambuyo mvula, makamaka ngati nyengo yofunda, ngakhale otentha, mukhoza kuona utawaleza. Pamene bowa mvula, ndiko kuti, dzuwa zobisika kuseri kwa mitambo, izo Tingaone mwachindunji mu mvula. Kumachitika pamene m'malovu ang'ono ndi evaporating kapena kugwa madzi dzuwa likuwala. Izi ndi wokongola zachilengedwe chotchuka kwambiri ndi ana, kuti nthawi zina funso: "? N'chifukwa chiyani mvula" - wina amanena: "Anthu kuona utawaleza."
