Aims Speak about Isentropic analysis Aerological diagram Using pseudo potential temperature in atmospheric sciences http://commons.wikimedia.org

Isentropic analysis Pseudo adiabatic process …is adiabatic process is a process, which happens with saturate air, when all liquid moisture is absent. There are no big difference between wet adiabatic line and pseudo one, but the first one is reversible.

Pseudo-equivalent temperature Tp for wet particle …is the temperature which this particle gets after dry adiabatically rising up to condensational level, then pseudo adiabatically rising up to full condensation of water vapour and then dry adiabatically sinking in the first level.

Pseudo potential temperature Θp …is the temperature which a particle gets after pseudo adiabatically rising up to full condensation of water vapour and then dry adiabatically sinking in 1000 hPa level. http://meteoweb.ru

The formula for pseudo potential temperature where Tp is pseudo equivalent temperature, p – pressure, (k-1)/k=0.286 is a constant for aerological diagram.

Conclusion Pseudo potential temperature characterizes dry adiabatic process and pseudo one. It uses in aerological diagram and it’s an important parameter for analysis the atmosphere.
