The science of space weather.
The basic physics underpinning space weather is reviewed, beginning with a brief overview of the main causes of variability in the near-Earth space environment. Although many plasma phenomena contribute to space weather, one of the most important is magnetic reconnection, and recent cutting edge research in this field is reviewed. We then place this research in context by discussing a number of...
متن کاملSpace Weather Effects on Communications
An overview of historical and contemporary impacts of the solar and geospace environments on communications systems. Abstract In the last century and one-half, since the invention and deployment of the first electrical communication system – the electrical telegraph, the variety of communications technologies that can be affected by natural processes occurring on the Sun and in the space enviro...
متن کاملCosmic rays and space weather: effects on global climate change
We consider possible effects of cosmic rays and some other space factors on the Earth’s climate change. It is well known that the system of internal and external factors formatting the climate is very unstable; decreasing planetary temperature leads to an increase of snow surface, and decrease of the total solar energy input into the system decreases the planetary temperature even more, etc. Fr...
متن کامل3.6 Space Weather Effects on Soho and Its Leading Role in the Early-warning System for Space Weather
Since its launch on 2 December 1995, the Solar and Heliospheric Observatory (SOHO) has provided an unparalleled breadth and depth of information about the Sun, from its interior, through the hot and dynamic atmosphere, and out to the solar wind. In addition SOHO has several times demonstrated its leading role in the early-warning system for space weather. SOHO is in a halo orbit around the L1 L...
متن کاملSpace 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...
