摘要: This paper describes an updated scheme for parametrisation of atmospheric convection to be used in the Met Office Atmospheric Dispersion Model (NAME III). In this scheme, vertical transport particles due is represented a 1-dimensional model based on ‘mass-flux’ approach. Empirical formulas are obtain mass fluxes and convective precipitation closure. Results compared with from single column version Office’s NWP show good agreement. Lastly, alternative method estimate by calculating dilute parcel ascent also discussed.
