👉 A blowoff is a term used in meteorology and astrophysics to describe the process by which particles are ejected from the Earth's atmosphere. Specifically, it refers to the outward motion of gas molecules away from the planet's surface due to collisions with the atmosphere. In the context of astronomy, it involves the movement of gas particles outwards from the Earth's surface. This is often referred to as a "blowoff" or "outflow" in meteorology and astrophysics,
