Unyaka nonyaka, kokubini kwiPacific nakwizitshingitshane zeAtlantic (okanye iinkanyamba, ukuba siseAsia) zenza into enokubanamandla amancinci, ukuba namandla okutshabalalisa yonke into esendleleni yabo. Kodwa, Kuya kwenzeka ntoni ukuba iinkqwithela zesibhakabhaka zibethe uMhlaba?
Le, nangona isenokuba (kwaye, asizukuyikhanyela, kufanele ukuba ibe) yiphupha nje elibi, into engeyonyani, ngelishwa isifundo sitsho ngenye indlela. Akunakulindeleka, ewe, kodwa kunokwenzeka emva kwayo yonke loo nto.
Yintoni iinkanyamba zasemajukujukwini?
Ukuqonda ukuba zenziwe njani, kuya kufuneka sithethe malunga neLanga okanye, ngakumbi ngakumbi, umoya welanga. Olu hlobo lomoya lubangela ukukhula kwe Ukungazinzi kukaKelvin-Helmholtz. Ikwabizwa ngokuba ngamaza kaKelvin okanye amaza e-cirrus ka-Kelvin-Helmholtz, kwenzeka xa ukuhamba kwenzeka ngaphakathi kolwelo oluqhubekayo okanye xa kukho umahluko wesantya kunxibelelwano phakathi kwamanzi amabini.
Nangona zingaphezulu kwama-500 eekhilomitha kude, uKatarina Nykyri, umphandi eFlorida Centre for Space and Atmospheric Research, ubonise ukuba inokuvelisa ukunyuka kwamaxesha okuhamba rhoqo kwimigca yomhlaba yemagnethi kwaye inxibelelane namasuntswana akwibhanti yemitha.
Baza kuwuchaphazela njani uMhlaba?
Iinkanyamba zesithuba yingozi yokwenene kunxibelelwano ngesathelayithi kunye nokuthunyelwa emajukujukwini. Zizo »enye yeendlela eziphambili zomoya welanga othwala amandla, ubunzima kunye namandla kwi-magnetosphere; ngenxa yoku, zichaphazela indlela amaza kaKelvin-Helmholtz akhula ngokukhawuleza ngayo kunye nobungakanani bawo. '
Ukungazinzi okubangelwa yiplasma kuya kubangela ukuba umhlaba uzibuthe, ukwazi yenza amaqela amandla eshushu malunga neekhilomitha ezingama-67 amawaka ukusuka kwiplanethi. Ukuthathela ingqalelo oku, kubalulekile ukuqonda iindlela ezichaphazela ukukhula kunye neempawu zezi zinto.
