An Advanced System for Monitoring Geomagnetic Environments by the Japan Meteorological Agency

The Japan Meteorological Agency (JMA) has developed an advanced system to monitor geomagnetic environments consisting of magnetometers and monitoring cameras. The new system calculates the magnetic moments and positions of sources of artificial disturbances and then visually identifies the sources. The intensity and location of a source of artificial disturbance are calculated assuming the sour...

Outline of the Typhoon Ensemble Prediction System at the Japan Meteorological Agency

The Japan Meteorological Agency (JMA) began operation of a new Ensemble Prediction System (EPS) known as the Typhoon EPS (TEPS) in February 2008. TEPS has been designed to improve track forecast targeting for tropical cyclones (TCs) in the Regional Specialized Meteorological Center (RSMC) Tokyo Typhoon Center’s area of responsibility within the framework of WMO. It runs up to four times a day w...

Outline of the High Resolution Global Model at the Japan Meteorological Agency

The Japan Meteorological Agency (JMA) upgraded the resolution of the Global Spectral Model (GSM) from TL319L40 to TL959L60 on 21 November 2007, when the Typhoon Model retired from operational use. Since then, tropical cyclone (TC) track and intensity forecasts have been supported by GSM only. GSM provides numerical weather prediction (NWP) products four times a day for all TCs existing globally...

The weather radar system of north-western Italy: an advanced tool for meteorological surveillance

North-Western Italy is a geographical region characterized by complex orography with many river catchments. Severe meteorological conditions frequently leads to flood situations due to very high rainfall amounts. In addition to a quite dense net of rain gauges, in the last three years two Doppler radar systems have been installed to provide a continuous monitoring of the region. The Bric della ...
