Space weather and risk management
The term space weather is used for the solar driven variability in particle and electromagnetic conditions of the near-Earth space that may harm the performance of ground-based and space-borne technology. The European Union (EU) and the European Space Agency (ESA) have started a common programme called the Global Monitoring for Environment and Security (GMES). Many of the GMES operational servi...
متن کاملA general perspective of extreme events in weather and climate
One of the most important problems in meteorology, physical oceanography, climatology, and related fields is the understanding and dynamical description of multi-scale interactions. Multi-scale interactions are closely related to extreme events in climate and, therefore, of great practical importance. Here an extreme event is defined in terms of the non-Gaussian tail (sometimes also called a we...
متن کاملAn Integrated Management System of Multipoint Space Weather Observation
An outline of a planned system for the global space-weather monitoring network of NICT (National Institute of Information and Communications Technology) is given. This system can manage data collection much easier than our current system, by installations of autonomous recovery, periodical state monitoring, and dynamic warning procedures. According to a provisional experiment using a network si...
متن کاملNorth Europe power transmission system vulnerability during extreme space weather
Space weather driven by solar activity can induce geomagnetic disturbances at the Earth's surface that can affect power transmission systems. Variations in the geomagnetic field result in geomagnetically induced currents that can enter the system through its grounding connections, saturate transformers and lead to system instability and possibly collapse. This study analyzes the impact of extre...
متن کاملThe impact of space weather on communication
As a preliminary to the studies conducted by the individual Working Groups, a review has been undertaken of topics which are relevant to the space-weather phenomena that can occur. The ways in general that these can influence the state of the ionosphere are discussed. The various changes in propagation parameters that arise on Earth-space and terrestrial radio paths via the ionosphere are liste...
