Kodi chimango ndi chiyani ndipo chimapangidwa motani?

Nyanja pa dziko lathu lapansi ndi malo omwe nthawi zonse akhala akuthandizira kudziwa za dziko lapansi, komanso za nyengo zomwe zimadziwika. Gawo lalikulu la "maphunziro" lidachitidwa ndi oyendetsa sitima, popeza miyoyo yawo idalira makamaka za chidziwitso chawo cha nyanja ndi zikhalidwe zawo za nyengo.

Motero, chiwerengero cha anthu ogwira ntchito panyanja chinapereka maziko a kufufuza mphepo yamalonda. Kuonjezera apo, adatchulidwanso kuti "mahatchi" komwe mphepo sizinali zonse. Deta yamtunduwu inatipatsanso ife kumvetsa chomwe chimphepo chiri.

Pali malo m'mphepete mwa nyanja komwe kayendetsedwe ka mlengalenga kamadziwika ndi kawirikawiri. Monsoon - mtundu wa mphepo yamtundu uwu. Mu njira zambiri zimachokera kwa iwo kuti nyengo yam'mlengalenga imadalira. Izi zimaonekera makamaka m'madera akumidzi a m'nyanja ya Indian.

Koma momwe mungamvetsetse chiwonongeko, ngati simukudziwa bwino za maphunziro awo? Kuti mumvetsetse njirayi, muyenera kumvetsa kuti pamwamba pa kontinenti ndipamwamba kwambiri pamlengalenga. Monga momwe mukudziwira pa njira yochuluka ya masukulu a sayansi, mphepo imapangidwira chifukwa mulu wa mpweya umayenda kuchoka kumalo otsika kwambiri kuti ufike pamtunda.

Koma msolo amapangidwa mosiyana. M'chilimwe, Hindustan yomweyo ndi madera ena onse a Eurasian continent amawotcha kwambiri, zomwe zimapangitsa kuti kuchepa kukhale kovuta. Koma pamwamba pa nyanja ndipamwamba kwambiri.

Apa ndiyomwe yankho lagona pa funso la mvula. Ndi mphepo yamkuntho yotentha yothamanga kuchokera panyanja kupita kudziko. Komanso, imakhala yonyowa kwambiri, chifukwa imadzaza ndi madzi kuchokera pamwamba. Kotero, pa nthaka inapezeka mu "labotale" yamakono yomwe imakhala mvula yambiri komanso yamvula.

Ndi mchenga umene umapereka malo okhala m'mphepete mwa nyanja kukhala chonde chokwanira, koma okhala m'mayiko awa "akuyenera" kuthyola madzi osefukira, pamene mitsinje yamadzi imatsuka mizinda yonse m'nyanja.

Chilichonse chimasintha m'nyengo yozizira, pamene zida zotchedwa "nthaka" zimachokera kumadera otentha a m'madera akummwera. Mosiyana ndi "ogwirizana" awo, iwo sanali okhudzidwa ndi chinyezi cha nyanja.

Choncho, mphepo izi zimayambitsa chilala chambiri, chomwe chimapitilira mpaka nyengo yotsatira yamvula. Choncho, nyengo ya mvula (yonyowa) siimatha nthawi yayitali, koma kuchuluka kwa mphepo yomwe yagwera nthawiyi ndi yomwe imalola kuti zomera zizikhalabe mpaka chaka chamawa.

Izi ziyenera kunenedwa kuti m'madera omwe ali ndi nyengo yapadera, pafupifupi kotala la anthu ambiri padziko lapansi. Ku Northern Hemisphere, amakhala mu mvula kuyambira June, ndipo kumwera kumapeto kwa December.

Sitikuyankhula mwachangu za kuchuluka kwa mphepo. Kotero, malo a Cherrapunji ku India ndi "opambana kwambiri" mwa kuchuluka kwa madzi akugwa kuchokera kumwamba. Kwa tsiku lirilonse, pamene chimphepo chimalamulira dzikoli, chithunzi chake chiri mu nkhaniyi, pamakhala mita yonse ya mphepo!

Choncho, mphepo izi zimathandiza kwambiri pakukula kwa nyengo yonse. Popanda iwo, moyo wa anthu mamiliyoni ambiri sungatheke.

Tsopano inu mukudziwa kwenikweni chomwe chimphepo chiri.
