U fiirso marinka hoose ka dibna ka jawaab su'aasha kadib isla luqadda marinka: Marinka: 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 buufinaya la qayb weyn oo dhanka buurta ridge; inta badan arkay on khariidadaha cimilada Maraykanka bari ee Rocky Mountains, iyo mararka qaarkood bari ee Appalachians ah, halkaas oo ay ka yar tahay cad. "Waxaa laga yaabaa in la sameeyay labada natiijada ka mid ah cadaadiska adiabatic ee hawada dhaadhaca dhinaca lee ee buurta, ama iyada oo loo marayo cyclogenesis ka dhalatay "is-dhexgalka horizontal la xiriira fidinta toosan ee tiirarka hawada gudbaya ridge iyo hoos u dhaca lee dhaadhac". Su'aal: Sidee loo sameeyaa lee trough?
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
