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 weather. The combination of moisture and temperatures determine the stability of air and the resulting weather. Cool, dry air: stable and resists vertical movement Web212 APPENDIX A. ATMOSPHERIC STABILITY CLASSIFICATION SCHEMES Gifford (1976) reviewed stability typing schemes and preferred a scheme which uses the Monin-Obukov length, L, defined by Here u* is the friction velocity, Cp is the heat capacity of air, pair is the ambient air density, T is the ambient temperature at the reference height, k is …
