The spatial and temporal radio wave delay of the Global Positioning System (GPS) signal can be manipulated to estimate the precipitable water vapor (PWV) which favorable for meteorological application...
Recent testing and validation have found that the Geostationary Operational Environmental Satellite (GOES) microburst products are effective in the assessment and short-term forecasting of downburst p...
The use of products from ground-based GNSS observations in meteorological nowcasting
The use products from ground-based GNSS observations meteorological nowcasting
2010/9/10
Convective rainfall is often focalized in areas of moisture convergence. A close relationship between precipitation and fast variations of vertically-integrated water vapour (IWV) has been found in nu...

Artificial neural-network technique satellite imagery
2010/1/27
The term nowcasting reflects the need of timely and accurate predictions of risky situations related to the development of severe meteorological events. In this work the objective is the very short te...
Empirical Mode Decomposition in 2-D space and time：a tool for space-time rainfall analysis and nowcasting
2-D space Empirical Mode Decomposition space-time rainfall
2009/5/18
A data-driven method for extracting temporally persistent information, at different spatial scales, from rainfall data (as measured by radar/satellite) is described, which extends the Empirical Mode D...
Rainfall nowcasting by at site stochastic model P.R.A.I.S.E.
Rainfall Prediction of Rainfall Amount Inside Storm Events stochastic model
2009/5/8
The paper introduces a stochastic model to forecast rainfall heights at site: the P.R.A.I.S.E. model (Prediction of Rainfall Amount Inside Storm Events). PRAISE is based on the assumption that the rai...
