TIED TO SOLAR ACTIVITY. “The electron fluxes maximize during the declining phase of the solar activity when the high-speed streams are most frequent, and minimize during solar minimum.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

ELECTRON STREAMS. “These periods are effective drivers of medium-level activity in the high-latitude magnetosphere and in the ring current. The high-speed streams are especially efficient in accelerating relativistic electron populations in the outer van Allen belt.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

FEROCIOUS WINDS. “High-speed solar wind streams encountering the Earth most often originate from low-latitude coronal holes. Such high-speed streams are often associated with strong Alfvénic fluctuations leading to strong fluctuations of the IMF Bz and solar wind velocity.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

MAGNETIC STORMS. “Similarly to ICMEs, any coherent solar wind structures including long-lasting, high-intensity southward interplanetary fields drive magnetic storm activity with its many signatures in the magnetosphere-ionosphere system.” (ICME= Interplanetary coronal mass ejection). https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

11 YEAR CYCLE. “While the strongly southward field inside the ICME proper tends to drive high ring current activity, the more variable fields and densities in the sheath region drive strongest activity at the high-latitude auroral regions. As ICMEs are more frequent during solar maximum than during solar minimum, they contribute to the 11-year cycle in magnetospheric activity.” (ICME= Interplanetary coronal mass ejection). https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

“SOLAR ENERGETIC PARTICLES affect the space environment in multiple ways. In the outer magnetosphere (especially near the geostationary region), their presence is a hazard for the satellite systems and instrumentation. If they become trapped in the inner magnetosphere dipolar field, they populate the van Allen belts, residing in the magnetosphere for extended periods.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

SOLAR CYCLES. “The irradiance exhibits both long-term (solar cycle) variations as well as shorter term changes related to active solar events, both of which can be monitored using the F10.7 radio flux as a proxy.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

SOLAR HEAT. “This most familiar form of the Sun’s influence on the Earth is a factor also for space weather: Increases of the solar irradiance cause heating of the upper atmosphere, which affects the drag experienced by low-Earth-orbiting satellites.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn
