WebADVERTISEMENTS: Different forms of precipitation (dew, fog, rainfall, frost, snowfall, hailstorm etc.) depend on stability and instability of the atmosphere. The air without vertical movement is called stable air while unstable air undergoes vertical movement (both upward and downward). An airmass ascends and becomes unstable when it becomes … WebIn an unstable atmosphere, small vertical air movements tend to become larger, resulting in turbulent airflow and convection. Instability can lead to turbulence, clouds, and severe …

WebATMOSPHERIC STABILITY (Continued) 10/20/99. We know that an unsaturated parcel will rise, expand, and cool at a rate of 9.8 C per kilometer. We also know that if the parcel becomes saturated, then the latent heat released by condensing water vapor will make the parcel cool at a different, lesser rate - 4 to 7 C per kilometer. WebAtmospheric Stability Concepts. Atmospheric stability helps determine whether clouds (and precipitation) form or not. The atmosphere could be. stable, and so the air parcel remains stationary, unstable, and the air … small stocks worth buying

When you think of the word “stable,” you typically think of an object that is unlikely to change or something that is balanced. The opposite is true with something that is “unstable”. An unstable object is likely to fall or change position with time. The same is true with clouds. When you see a fluffy cumulus cloud, you … See more There are many different types of thermodynamic diagrams, but the main one we will discuss are Skew-T Log-P diagrams, so-named because the isotherms (lines of equal temperature, T) on the diagram are … See more http://apollo.lsc.vsc.edu/classes/met130/notes/chapter6/stability_intro2.html WebFeb 1, 2024 · The clearest way to observe the difference between a stable and an unstable air mass is to look at the clouds: A stable atmosphere will have largely flat layers of cloud, which may exhibit some lumpiness but … highway conditions nc
