A high-order conservative collocation scheme and its application to global shallow-water equations [PDF]

Geoscientific Model Development, 2015
In this paper, an efficient and conservative collocation method is proposed and used to develop a global shallow-water model. Being a nodal type high-order scheme, the present method solves the pointwise values of dependent variables as the unknowns ...

Estimating 1min rain rate distributions from numerical weather prediction [PDF]

, 2017
Internationally recognized prognostic models of rain fade on terrestrial and Earth-space EHF links rely fundamentally on distributions of one-minute rain rates. Currently, in Rec. ITU-R P.837-6, these distributions are generated using the Salonen Poiares-

Influence of the upper gravity-wave damping layer on precipitation over complex terrain

Frontiers in Environmental Science, 2022
The upper boundary condition of a numerical model can significantly influence the model prediction results. This study used the Weather Research and Forecasting model to introduce the Rayleigh damping layer in the complex terrain of southern Gansu, China.
