Feb 1, 2021 · Learn how meteorologists use temperature profiles and cloud types to distinguish between stable and unstable air masses. Find out what causes air to rise and form different types of clouds, and how instability leads to showers and thunderstorms.
Jul 21, 2022 · Learn the difference between stable and unstable air masses, their characteristics, and how they affect weather and flying conditions. Find out how to identify and measure air stability and conditional stability using adiabatic lapse rate and environmental lapse rate.
When an air mass is unstable, the element of the air mass that is displaced upwards is accelerated by the pressure differential between the displaced air and the ambient air at the (higher) altitude to which it was displaced.
In the first of a new series, Met Office meteorologist Alex Deakin explains with the help of a few simple household items how unstable air causes cumulus clo...
Temperature and dewpoint determine an air mass’s stability. Stable air resists vertical motion and tends to bring benign (though not necessarily good) weather, while unstable air can bring turbulence and severe weather. Stable Air vs Unstable Air
Learn how thunderstorms form, what causes them to be severe, and how to stay safe. Unstable air is one of the three ingredients needed for thunderstorms to develop, along with moisture and a lifting mechanism.
May 24, 2024 · Air is unstable when the environmental lapse rate is greater than the dry adiabatic rate. Under these conditions, a rising parcel of air is warmer and less dense than the air surrounding it at any given elevation.
