- Аннотация: A software package (OZO, Omega–Zwack– Okossi) was developed to diagnose the processes that af- fect vertical motions and geopotential height tendencies in weather systems simulated by the Weather Research and Forecasting (WRF) model. First, this software solves a gen- eralised omega equation to calculate the vertical motions as- sociated with different physical forcings: vorticity advection, thermal advection, friction, diabatic heating, and an imbal- ance term between vorticity and temperature tendencies. Af- ter this, the corresponding height tendencies are calculated with the Zwack–Okossi tendency equation. The resulting height tendency components thus contain both the direct ef- fect from the forcing itself and the indirect effects (related to the vertical motion induced by the same forcing) of each physical mechanism. This approach has an advantage com- pared with previous studies with the Zwack–Okossi equa- tion, in which vertical motions were used as an independent forcing but were typically found to compensate the effects of other forcings. The software is currently tailored to use input from WRF simulations with Cartesian geometry. As an illustration, re- sults for an idealised 10-day baroclinic wave simulation are presented. An excellent agreement is found between OZO and the direct WRF output for both the vertical motion and the height tendency fields. The individual vertical motion and height tendency components demonstrate the importance of both adiabatic and diabatic processes for the simulated cy- clone. OZO is an open-source tool for both research and education, and the distribution of the software will be supported by the authors.
