Solar Wind Charge Exchange (SWCX) – Definition & Detailed Explanation – Space Weather Glossary

I. What is Solar Wind Charge Exchange (SWCX)? Solar Wind Charge Exchange (SWCX) is a phenomenon that occurs when high-speed solar wind particles interact with neutral atoms in the Earth’s exosphere, causing them to become charged. This process results in the emission of X-rays that can be detected and studied by scientists. SWCX plays a … Read more

Solar Energetic Particles (SEPs) – Definition & Detailed Explanation – Space Weather Glossary

I. What are Solar Energetic Particles (SEPs)? Solar Energetic Particles (SEPs) are high-energy particles that are emitted from the sun during solar flares and coronal mass ejections (CMEs). These particles can travel at nearly the speed of light and can have a wide range of energies, from a few million electron volts to several billion … Read more

Thermosphere Weather – Definition & Detailed Explanation – Space Weather Glossary

I. What is the Thermosphere? The thermosphere is the layer of Earth’s atmosphere located above the mesosphere and below the exosphere. It is situated between approximately 80 kilometers and 550 kilometers above the Earth’s surface. The thermosphere is known for its extremely high temperatures, which can reach up to 2,500 degrees Celsius due to the … Read more

Polar Cap Absorption (PCA) – Definition & Detailed Explanation – Space Weather Glossary

I. What is Polar Cap Absorption (PCA)? Polar Cap Absorption (PCA) is a phenomenon that occurs in the Earth’s polar regions when solar wind particles interact with the Earth’s magnetic field. This interaction can lead to the absorption of high-energy particles in the ionosphere, causing disturbances in the Earth’s upper atmosphere. PCA is most commonly … Read more
