Mkhalidwe wa nyengo ku Antarctica ndiwovuta chifukwa chamalo ozungulira dzikoli. Kawirikawiri kutentha kwa mpweya kumakwera pamwamba pa 0 madigiri Celsius kontinentiyo. Antarctica yaphimbidwa ndi matalala akulu. Dzikoli likukhudzidwa ndi mpweya wozizira, womwe ndi mphepo zakumadzulo. Mwambiri, nyengo zakudzikoli ndi zowuma komanso zovuta.
Malo ozungulira nyengo yaku Antarctic
Pafupifupi gawo lonse la kontrakitala lili mdera la Antarctic nyengo. Kukula kwa chivundikiro cha madzi oundana kumapitilira mamita 4500,000, momwe Antarctica imadziwika kuti kontinenti yayikulu kwambiri padziko lapansi. Kuposa 90% ya radiation ya dzuwa imawonekera kuchokera kumtunda kwa madzi oundana, motero dzikolo silitentha. Kunalibe mphepo, ndipo kulibe mvula zoposa 250 mm pachaka. Avereji ya kutentha kwamasana ndi -32 madigiri, ndi usiku -64. Kutentha kochepa kumakonzedwa pa -89 madigiri. Mphepo zamphamvu zimadutsa kumtunda ndikuthamanga kwambiri, kukulira pagombe.
Nyengo yotentha
Chikhalidwe cha mtundu wa subantarctic chimafanana kumpoto kwa kontrakitala. Zizolowezi zofewetsa nyengo zikuwonekera pano. Mvumbi pano ndi yayikulu kuwirikiza, koma siyipitilira mulingo wapachaka wa 500 mm. M'chilimwe, kutentha kwamlengalenga kumakwera pang'ono kuposa madigiri 0. M'derali, madzi oundana amakhala ochepa pang'ono ndipo mpumulowo umasanduka malo amiyala okutidwa ndi ndere komanso moss. Koma kukopa kwanyengo yaku Arctic nyengo ndikofunikira. Chifukwa chake, kuli mphepo zamphamvu ndi chisanu. Nyengo zotere sizoyenera moyo wamunthu.
Malo ochezera ku Antarctic
Pamphepete mwa Nyanja ya Arctic, nyengo imakhala yosiyana ndi nyengo. Maderawa amatchedwa oat Antarctic. Kutentha kwapakati pa chilimwe ndi +4 madigiri Celsius. Mbali zina za kumtunda siziphimbidwa ndi ayezi. Mwambiri, kuchuluka kwa oases otere sikupitilira 0.3% ya dera lonse la kontrakitala. Pano mungapeze nyanja ndi mafunde a ku Antarctic okhala ndi mchere wambiri. Mmodzi mwa malo oyamba otseguka ku Antarctic anali Zigwa Zouma.
Antarctica ili ndi nyengo yapadera chifukwa ili ku South Pole Earth. Pali madera awiri azanyengo - Antarctic ndi Subantarctic, omwe amadziwika ndi nyengo yovuta kwambiri, momwe kulibe zomera, koma mitundu ina ya nyama ndi mbalame imakhala.
