New study reveals how space weather causes rapid fluctuations in Earth’s surface geomagnetic field.
Space Weather
Forecasting the Threat from the Sun
Ensemble techniques are opening a path toward space weather forecasts that give deeper understanding of the risk posed by each solar storm that approaches our planet.
How Space Storms Affect the Satellite Superhighway
A powerful numerical model reveals how space weather disturbs magnetic field at geosynchronous orbit.
Capturing Structural Changes of Solar Blasts en Route to Earth
Comparison of magnetic field structures for 20 coronal mass ejections at eruption versus Earth arrival highlights the importance of tracking structural evolution to refine space weather predictions.
Catching the Oncoming Radiation Storm
Improved processing enables satellite-based radiation sensors to match ground-based sensors in providing prompt warnings of the onset of atmospheric radiation storms that can endanger civil aviation.
Increasing Radiation Levels May Challenge Space Exploration
New research shows that solar radiation levels are growing 10% faster than previously believed and that the radiation environment in space will worsen with time.
Improving Temperature Forecasts in the Upper Atmosphere
Scientists are blending output from multi-year model runs to improve temperature forecasts in regions where satellites experience “drag,” in the hopes of avoiding future spacecraft collisions.
Space Weather: Exploiting Meteorology’s Toolkit
Space weather forecasting is benefiting, and can benefit much further, from concepts and tools already developed by the global meteorological community.
Preserving a 45-Year Record of Sunspots
Maps reveal how the Sun’s magnetic field evolves through solar cycles.
