A comparison of the rainfall forecasting skills of the WRF ensemble forecasting system using SPCPT and other cumulus parameterization error representation schemes

Atmospheric Research, 2019
The scientific community mainly uses ensemble systems to represent various sources of uncertainties and to produce better forecasts. The inability to choose accurate initial conditions leads to failed forecasts due to the well-known butterfly effect ...

Simulation of summer precipitation diurnal cycles over the Tibetan Plateau at the gray-zone grid spacing for cumulus parameterization

Climate Dynamics, 2020
The Tibetan Plateau (TP) is often referred to as the “water tower of Asia” or the “Third Pole”. It remains a challenge for most global and regional models to realistically simulate precipitation, especially its diurnal cycles, over the TP.

Parameterizations for convective transport in various cloud-topped boundary layers [PDF]

Atmospheric Chemistry and Physics, 2015
We investigate the representation of convective transport of atmospheric compounds by boundary layer clouds. We focus on three key parameterizations that, when combined, express this transport: the area fraction of transporting clouds, the upward

Diagnostic evaluation of extreme winter rainfall events over the Arabian Peninsula using high‐resolution weather research and forecasting simulations

Meteorological Applications, 2022
The sensitivity of different cumulus physical parameterization schemes for simulating extreme winter precipitation events over the Arabian Peninsula (AP) is investigated using a high‐resolution weather research and forecasting (WRF) model. For winters in

A review of the theoretical basis for bulk mass flux convective parameterization [PDF]

, 2009
Most parameterizations for precipitating convection in use today are bulk schemes, in which an ensemble of cumulus elements with different properties is modelled as a single, representative entraining-detraining plume.
