| Abstract: |
| The present study analyzed the research of Rossby, Simpson, Lasheen and Saunders on dry-adiabatic process and wet-adiabatic process of atmosphere and proposed the accurate formula of Rossby-Simpson pseudo-equivalent potential temperature base on the definition. The formula included the Rossby pseudo-equivalent potential temperature (θse) and the Simpson pseudo-equivalent potential temperature (θss). Five checking tables were presented, and the reason why the values differed from that of previous studies was discussed. |
| Key words: Rossby Simpson Lasheen potential temperature pseudo-equivalent potential temperature accurate calculation. |
