WebJan 20, 2024 · Updated on January 20, 2024. Stability (or atmospheric stability) refers to air's tendency to either rise and create storms (instability), or to resist vertical movement … Webinstability is dependent upon the status of the moisture in the atmosphere (unsaturated or saturated), is called conditional instability. In general the troposphere is rather stable …
WebJul 25, 2024 · In an unstable atmosphere, the updraft may climb up through the troposphere into the tropopause or stratosphere, where the air temperature starts to increase with altitude. As the updraft slows down, it flattens out, resulting in the anvil and flat top you see on a mature or dissipating thunderstorm. And that, as they say, is how … WebFeb 1, 2024 · Then, there is the intermediate position between stability and instability, a phenomenon known as conditional instability.

WebThe stability or instability of the atmosphere really boils down to the question of which is greater—the environmental lapse rate, or the parcel's lapse rate. ... That is, the stability depends on, or is conditional upon, whether the air is saturated or not. Such situations, which are the most common in the atmosphere, are said to be ...
WebAssessment of Vertical Stability Air Parcels and Conditional Instability The vertical stability of the atmosphere, and hence its ability to support convection, is often analyzed using the assumptions of the parcel theory.
