| 英文摘要 | A new invariant, the second order potential voracity (SPV), is derived in this paper. SPY is the dot product of vorticity and the potential voracity (PV) gradient, and is proven conservative for a compressible, adiabatic and frictionless atmosphere. Research shows that the new invariant may be used to indicate the evolution of PV, because SPV includes all the information that determines PV evolution: the wind field, and the PV gradient. Furthermore, SPV is capable of diagnosing heavy precipitation because of the strong signals it presents in areas of heavy rainfall. SPY also shows great potential as a comprehensive conserved quantity for indicating the dynamical tropopause and baroclinic instability. |
