Space weather may disrupt electric power grids, telecommunication grids, satellite-based systems including navigation systems, air traffic and oil, gas and other pipelines.

Definitions

European Definition

Space weather can be defined as conditions on the Sun and in the solar wind, magnetosphere, ionosphere and thermosphere that can influence the performance and reliability of space-borne and ground-based technological systems and can endanger human life or health. [1]


International Organisation Definitions

WMO

Space Weather is defined here as the physical and phenomenological state of the natural space environment including the sun and the interplanetary and planetary environments. [2]

Space Weather encompasses the conditions and processes occurring in space, including on the sun, in the magnetosphere, ionosphere and thermosphere, which have the potential to affect the near-Earth environment. [3]


WHO

Space weather refers to the variable conditions on the Sun and in the space environment that can influence the performance and reliability of spaceborne and ground based technological systems, as well as endanger life or health. [4]

European Definitions

National Definitions

Belgium

Ruimteweer is de veranderlijke toestand van de omgeving in de ruimte die een invloed uitoefent op de Aarde en op haar technologische systemen. [5]


Canada

Space Weather refers to a collection of physical processes, beginning at the Sun and ultimately affecting human activities on Earth and in space. [6]

La météo spatiale est un terme qui désigner une série de processus physiques émanant du Soleil et qui peuvent affecter les activités humaines sur Terre et dans l'espace. [7]

Space weather describes the dynamic conditions in the Earth’s outer space environment. [8]
Space weather includes any and all conditions and events on the sun, in the solar wind, in near-Earth space and in our upper atmosphere that can affectspace-borne and ground-based technological systems and through these, human life and endeavor. Heliophysics is the science of space weather.
TWH
Space weather refers to variations in the space environment between the sun and Earth (and throughout the solar system) that can affect technologies in space and on Earth. [9]
Space weather can disrupt the technology that forms the backbone of this country’s economic vitality and national security, including satellite and airline operations, communications networks, navigation systems, and the electric power grid.
AMS
Space weather refers to the variable conditions on the Sun and in the space environment that can influence the performance and reliability of spaceborne and ground based technological systems, as well as endanger life or health. [10]
