#horizontal transport

• Advection — The horizontal movement of an air mass or fluid, accompanied by the transport of its physical properties (such as temperature, moisture, salinity, or density); the physical process of large-scale bulk transport from one point to another within a fluid medium. In meteorology, advection is a key factor in weather dynamics, strictly distinguished from convection (vertical movement) and causing sharp temperature shifts.
• Advective — Relating to advection; caused, induced, or driven by the process of advection (the horizontal transport of an atmospheric or fluid property, such as mass, heat, or moisture). In synoptic meteorology, the term describes complex phenomena triggered by large-scale horizontal air mass movements, such as advective fog or advective frost, both originating from the sudden intrusion of an air front with contrasting thermal traits over a region.
