WebAbstract. A commonly employed explanation for single- and multiple-banded clouds and precipitation in the extratropics is slantwise convection due to the release of moist symmetric instability (MSI), of which one type is conditional symmetric instability (CSI). This article presents a review of CSI with the intent of synthesizing the results ... 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 …

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. WebStart by keeping in mind some key "benchmark" lapse rates that will help you as you assess the stability of specific atmospheric layers: the dry-adiabatic lapse rate: 9.8 degrees Celsius per kilometer (you can use about 10 degrees Celsius per kilometer as a proxy) the moist-adiabatic lapse rate: roughly 6 degrees Celsius per kilometer, but ... great clips martinsburg west virginia

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.
