Kafukufuku wazinthu zakuthambo, kuphatikiza ma anticyclone, akhala akuchita kwanthawi yayitali. Nthawi zambiri nyengo imakhalabe chinsinsi.
Chikhalidwe cha anticyclone
Anticyclone amadziwika kuti ndiwofanana ndendende ndi mphepo yamkuntho. Yotsirizira, nayenso, ndi vortex yayikulu yochokera mumlengalenga, yomwe imadziwika ndi kutsika kwa mpweya. Mphepo yamkuntho imatha kupangidwa chifukwa cha kuzungulira kwa dziko lathu lapansi. Asayansi akuti chodabwitsa cha mlengalenga ichi chikuwonetsedwa pazinthu zina zakuthambo. Mbali yapadera yamimphepo yamkuntho ndi mafunde am'mlengalenga oyenda molowera kumpoto chakumadzulo ndikulowera kumwera kumwera. Mphamvu zazikulu zimapangitsa kuti mpweya uziyenda mwamphamvu kwambiri, kuwonjezera apo, chodabwitsa ichi chimadziwika ndi mvula yamphamvu, kugwa kwamvumbi, mabingu amvula ndi zochitika zina.
M'dera la ma anticyclones, zimawonetsa kuthamanga. Air misa mu izo zimayenda mozungulira kumpoto kwa dziko lapansi ndi counterclockwise - kum'mwera. Asayansi apeza kuti zochitika zam'mlengalenga zimathandizira nyengo. Pambuyo pa anticcloneyo, nyengo yabwino imakhala m'derali.
Zochitika ziwiri zam'mlengalenga zili ndi chinthu chimodzi chofanana - zimangowoneka m'malo ena apadziko lapansi. Mwachitsanzo, nthawi zambiri amakumana ndi chimphepo cham'madera omwe pamwamba pake pali ayezi.
Ngati mphepo zamkuntho zibuka chifukwa cha kuzungulira kwa dziko lapansi, ndiye kuti ma anticyclone - okhala ndi mpweya wambiri mu chimphepocho. Liwiro la kayendedwe ka ma vortices apakati pa 20 mpaka 60 km / h. Miyeso yamkuntho ndi kukula kwa 300-5000 km, anticyclones - mpaka 4000 km.
Mitundu yama anticyclones
Mavoliyumu ampweya okhala ndi ma anticyclone amayenda mwachangu kwambiri. Kuthamanga kwa mlengalenga mwa iwo kumagawidwa kotero kuti kumakhala kwakukulu pakati. Mpweya umayenda kuchokera pakati pa vortex mbali zonse. Nthawi yomweyo, kulumikizana komanso kulumikizana ndi magulu ena amlengalenga kulibe.
Ma anticyclone amasiyana malinga ndi komwe amachokera. Kutengera izi, zochitika zam'mlengalenga zimagawika m'magawo ena othamangira komanso otentha.
Kuphatikiza apo, ma anticyclone amasintha m'magawo osiyanasiyana, chifukwa chake adagawika:
- Kumpoto - m'nyengo yozizira, kuli mvula yaying'ono komanso mitambo, komanso nkhungu, chilimwe - mitambo;
- Kumadzulo - mvula yamkuntho imagwa m'nyengo yozizira, mitambo ya stratocumulus imawoneka, mvula yamabingu imagunda mchilimwe ndipo ma cumulus amakula;
- Kum'mwera - mitambo ya stratus, madontho akuluakulu, mphepo yamkuntho ngakhale matama amvula
- kum'mawa - chifukwa chakumapeto kwa izi, mvula yamphamvu, mvula yamabingu ndi mitambo ya cumulus ndizodziwika.
Pali madera ena omwe ma anticyclone sagwira ntchito ndipo amatha kukhala m'derali kwanthawi yayitali. Dera lomwe zochitika zam'mlengalenga zimatha kukhalapo nthawi zina zimakhala zofanana ndi makontinenti onse. Kuthekera kobwereza ma anticyclone ndikotsika kawiri ndi ma 2.5-3 kuposa amphepo zamkuntho.
Mitundu yambiri yama anticyclone
Pali mitundu ingapo yama anticyclone:
- Asia - imafalikira ku Asia konse; nyengo yamlengalenga;
- Arctic - kuchuluka kwapanikizika komwe kumawoneka ku Arctic; malo okhazikika azomwe zikuchitika mumlengalenga;
- Antarctic - yokhazikika m'dera la Antarctic;
- North America - amakhala kudera la North America;
- subtropical - dera lomwe lili ndi vuto lalikulu mumlengalenga.
Komanso kusiyanitsa pakati pa ma anticyclone okwera kwambiri ndi okhalitsa. Kutengera kuchuluka kwakanthawi kwam'mlengalenga m'maiko ena, nyengo imapangidwa.
