Abstract. A stochastic deep convection parameterization is implemented into the US Department of Energy (DOE) Exascale Earth System Model (E3SM) Atmosphere version 1.0 (EAMv1). This study evaluates its performance in simulating precipitation. Compared to default model, probability distribution function (PDF) rainfall intensity new simulation greatly improved. The well-known problem “too much li...

Spores of both Puccinia recondita f. sp. tritici and P. striiformis (brown rust and yellow rust of wheat) are thought to be primarily dispersed by wind. The results of experiments, using a rain simulator with uniform drop sizes (2.5, 3.4, 4.2 or 4.9 mm), on the effect of rain on dispersal of brown (leaf) rust and yellow (stripe) rust spores are reported. Experiments on both pathogens were done ...

This work presents an empirical simulation to estimate the extent to which weather affects consumer spending. For the spending prediction purpose, the regression technique has been applied on the historical daily data of the following meteorological parameters: temperature, snow, sun, rain and humidity. The experimental results demonstrate the effectives of the model for predicting sales trends...

Polarimetric radar variables of rainfall events, like differential reflectivity ZDR, or specific differential phase KDP, are better suited for estimating rain rate R than just the reflectivity factor for horizontally polarized waves, ZH. A variety of physical and empirical approaches exist to estimate the rain rate from polarimetric radar observables. The relationships vary over a wide range wi...

The Mekong River is the most important river in Southeast Asia. It has increasingly suffered from water-related problems due to economic development, population growth and climate change in the surrounding areas. In this study, we built a distributed Geomorphology-Based Hydrological Model (GBHM) of the Mekong River using remote sensing data and other publicly available data. Two numerical exper...

We show that the aerosol-cloud-precipitation system exhibits characteristics of the predator-prey problem in the field of population dynamics. Both a detailed large eddy simulation of the dynamics and microphysics of a precipitating shallow boundary layer cloud system and a simpler model built upon basic physical principles, reproduce predator-prey behavior with rain acting as the predator and ...
