WebMay 8, 2024 · conditional instability An atmospheric condition in which otherwise stable air, on being forced to rise (e.g. over a mountain barrier), cools at a rate less than that at which the temperature drops with height in the surrounding air. The rising air therefore becomes warmer than the surrounding air, and so continues to rise. This lesser rate of … WebDec 1, 2000 · 1. Introduction. Sherwood (2000) raises some excellent points regarding usage of the term conditional instability in atmospheric science. He discusses two ways that conditional instability is commonly used: the lapse-rate definition (i.e., the environmental lapse rate lies between the dry- and the moist-adiabatic lapse rates) and …

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 (stability). The simplest way to understand how stability works is to imagine a parcel of air having a thin, flexible cover that allows it to expand but prevents the air inside ... WebMar 31, 2024 · Now, let’s look at how these rates influence atmospheric conditions and weather. Atmospheric Stability, Instability & Conditional Instability Stability. Atmospheric stability occurs when the atmosphere (environmental lapse rate) cools slowly than a rising air parcel (dry adiabatic lapse rate) which is cooling at a faster rate. WebThis is one of the most common states of the atmosphere called conditional instability. The atmosphere is unstable if certain conditions are met otherwise it is stable. 1.

WebFeb 23, 2011 · Conditional Instability. If you cause dry air to rise, its temperature will drop due to adiabatic expansion. This vertical temperature gradient is called the dry adiabatic lapse rate. When the temperature gradient becomes sharper than this (i.e. the temperature drops sharply as altitude increases), the atmosphere becomes unstable.

WebInstability will increase further when the dewpoint near the surface increases. The addition of moisture makes the air less dense near the surface but more importantly releases more latent heat when air rises and condenses into precipitation. Air that is less dense and is warmer due to latent heat release will produce a more significant convection.
