U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Passage: A lee trough, oo sidoo kale loo yaqaano a trough firfircoon, waa "A trough cadaadis sameeyay dhinaca lee ee buurta ee xaaladaha halkaas oo dabaysha waxaa ka buuxa qayb weyn oo dhanka kale ah ridge buurta; badanaa lagu arko khariidadaha cimilada ee Maraykanka ee bariga Rocky Mountains, iyo mararka qaarkood bariga Appalachians, halkaas oo ay ka yar tahay la sheegay. " Waxaa loo sameyn karaa natiijada cadaadiska adiabatic ee hawada qubanaya ee dhinaca lee ee buurta, ama iyada oo loo marayo cyclogenesis oo ka dhalatay "isbadal jiif ah oo la xiriira fidinta toosan ee tiirarka hawada ee ka gudbaya dusha sare iyo hoos u dhaca lee slope".  Su'aal: sidee loo sameeyaa godka?
taas oo ay sabab u tahay cadaadiska adiabatic ee hawada hoos u dhacaya ee dhinaca hoose ee buurta, ama iyada oo loo marayo cyclogenesis oo ka dhalatay "is-dhexgalka toosan ee la xiriira fidinta toosan ee tiirarka hawada ee ka gudbaya dusha sare iyo hoos u dhaca dhaadhaca hoose
