1. 1. Convective Instability Yae Won Kim
2. 2. Stability v. Instability Refers to air mass ability to resist vertical motion. Instability means vertical air movements are larger and more turbulent. This can then lead to severe weather such as thunderstorms.
3. 3. How? Occurs when dry mid-level air moves over warm moist air in the lower atmosphere. Convection moves heat and water vapor upwards while moving dry, cooler air to lower levels. It continues to do this until the atmosphere becomes stable.
