Real-time prediction of urban-scale rainfall by use of a two-dimensional stochastic convection-diffusion model

Kawamura, A. ; Jinno, K. and Berndtsson, R. LU orcid (1992) p.751-758
Abstract

Presents a two-dimensional stochastic convection-diffusion model for use in real-time prediction of the space-time rainfall structure in urban areas. The model is used to parameterize the rainfall intensity from individual rain cells. Especially, we are interested to quantify the rainfall intensity resulting from different separable components of the rain cell. This is done by a Lagrangian approach and dividing the rain from one cell into rainfall resulting from apparent turbulent diffusion and development/decay as a consequence of cell morphological changes. The results can be used as first choice of parameter values when modeling rain cell movement over ungaged areas and the presented methodology can be used to study the effects of... (More)
