Weather At The Sun

The Sun emits energy, sometimes storms in the Sun release radiation and magnetic fields through the Solar System, sometimes passing through the earth and sometimes not.

Weather Around The Earth

When the radiation from the Sun reaches Earth, it runs into our planet's magnetic field and its atmosphere. The radiation and magnetic fields in space weather swirl around Earth. Earth is surrounded by the magnetosphere. It affects depending on what the storms from the Sun are like. But it also depends on how those storms flow around and through Earth's magnetosphere.

Changes In Space Weather

Like the climate on Earth, space weather is always changing. Some space weather storms form in minutes or hours. An "active region" in the Sun can last several days or weeks, which causes space storms during all that time. The sun has cycles; for example, the sunspot cycle of 11 years that brings storms.
