干线是一个狭窄的非锋面区，具有明显的水汽不连续，长期以来被认为是雷暴发展的优先位置。通过对几年数据的研究，提出了干旱线生命周期的概念模型。干线起源于大陆气团的后缘，与旧锋面一致。在移动过程中，它位于低空逆温西侧边缘的地表投影上。干线要么被新的冷空气爆发破坏，要么变得过于分散而难以辨认。
Abstract The dryline, a narrow non-frontal zone of sharp moisture discontinuity, has long been known as a preferential location of thunderstorm development. Through an examination of several years of data, a conceptual model of the dryline life cycle is developed. The dryline originates along the trailing edge of a continental air mass and is coincident with an old frontal surface. As it moves, it is located on the surface projection of the western edge of the low-level inversion. The dryline is destroyed either by a new cold air outbreak or by becoming too diffuse to be easily recognizable.
