Nowcasting, forecasting and warning for ionospheric propagation: tools and methods
Nowcasting ionospheric propagation
2015/9/14
The paper reviews the work done in the course of the COST 271 Action concerned with the development of tools and methods for forecasting, nowcasting and warning of ionospheric propagation conditions. ...
Development of algorithms and software for forecasting, nowcasting and variability of TEC
Development of algorithms software for forecasting
2015/9/14
Total Electron Content (TEC) is an important characteristic of the ionosphere relevant to communications. Unpredictable variability of the ionospheric parameters due to various disturbances limits the...
Real time monitoring for nowcasting and forecasting ionospheric space weatherin Europe with ground digisondes
ionosphere ionospheric nowcasting ionospheric forecasting space weather ionogram scaling digisonde ionospheric monitoring networks
2015/9/10
The Earth's ionosphere largely determines space weather effects on radio wave communications, navigation and
surveillance systems. Lately there has been an increasing demand for ionospheric nowcast a...
OPERATIONAL ASSIMILATION OF SNOW DEPTH MAPS FOR IMPROVED REAL TIME RUNOFF NOWCASTING WITH SPATIALLY DISTRIBUTED HYDROLOGICAL MODELS
Operational assimilation snow depth maps
2015/9/8
Representative real time information on snow depth and snow water equivalent is needed for several
practical purposes, above all avalanche warning and flood forecast and control in spring. This study...
Nowcasting the lightning activity in Peninsular Malaysia using the GPS PWV during the 2009 inter-monsoons
GPS PWV Lightning SAFIR Inter-monsoon Nowcasting
2015/8/17
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...
An upper-level undergraduate course entitled "Radar and Satellite Meteorology" has offered for the past five years at the Department of Atmospheric and Oceanic Sciences, University of Wisconsin-Madiso...
Nowcasting Business Cycles Using Toll Data
business cycles data mining evaluating forecasts macroeconomic forecasting new products transportation production forecasting nowcasting telemetry
2012/11/1
Nowcasting has been a challenge in the recent economic crisis. We introduce the Toll Index, a new monthly indicator for business cycle forecasting and demonstrate its relevance using German data. The ...
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...
An operational approach to the nowcasting of an intense thunderstorm over Liguria
operational approach Liguria
2010/1/27
In the period between late spring and early summer as well as in autumn, the Mediterranean is often affected by rapid development of intense convective systems. In some cases the operational NWP model...
Artificial neural-network technique for precipitation nowcasting from satellite imagery
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...
