Umbani
Umbani uyisimongotho semvelo esihilela ukuqathazwa komzuba okwenzeka kumoyambulunga phakathi kwezifunda ezimbili ezinomlelesa wamazuba. Isifunda esisodwa noma zombili zingaphakathi komoyambulunga, kanti isifunda sesibili ngezinye izikhathi senzeka phansi . Ngemva kombani, izifunda ziba zinqindeka amazuba ngokwengxenye noma ngokuphelele.
Umbani ubandakanya ukudedelwa kwesidlakalasi ngokushesha okukhulu emlinganisweni osiphakathi kwama -megajoule angama-200 nama-gigajoule ayisi-7. [1] Umoya ozungeza umbani ushisa ngokushesha ufike kumazingenkushisa angaba yizi- 30,000 °C (54,000 °F) . Kukhona nokukhishwa kwemiyonzi yenzuawonga ebangeni elibanzi lamabangacuphi, amanye abonakala njengokukhanya okubanizayo. Umbani ubangela nokuduma, umsindo ovela kuliza lomsinga okhuliswa ukushisa kohowo budeduze nokuqathazwa olwandiswa umfutho ngokuzumayo.
