The propagation of electromagnetic waves through the atmosphere at frequencies above 10 GHz is strongly influenced by oxygen, water vapor, clouds and, even more heavily, by rain. The scarcity of worldwide reliable rainfall data has pushed towards the development of models that could adequately reproduce real rain fields. This contribution presents the analysis of some spatial and temporal characteristics of rain cells for rainfall modeling purposes, based on an extensive database of weather radar images.

Abstract
The propagation of electromagnetic waves through the atmosphere at frequencies above 10 GHz is strongly influenced by oxygen, water vapor, clouds and, even more heavily, by rain. The scarcity of worldwide reliable rainfall data has pushed towards the development of models that could adequately reproduce real rain fields. This contribution presents the analysis of some spatial and temporal characteristics of rain cells for rainfall modeling purposes, based on an extensive database of weather radar images. The results obtained in this study are of key importance in the development of advanced cellular space-time rainfall models.| File | Dimensione | Formato | |
