Wondering if there is any correlation between the seeming increase in global fog reports and the instances of Coronal Mass Ejections or any other type of solar radiation. Asking Chat GPT...
ChatGPT seems to think there could be a correlation, but there are a number of confounding variables. FWIW.
Correlation does not necessarily mean causation.
You are an expert in data science, astronomy, and meteorology. Can a correlation between coronal mass ejections or any other electromagnetic radiations from the sun be correlated to fog creation globally?

Correlating coronal mass ejections (CMEs) or other solar electromagnetic phenomena with fog formation globally is an intriguing idea, but it is a complex and multifaceted question. Here's an analysis based on current knowledge:
1.
Fog primarily forms when air becomes saturated with moisture, leading to the condensation of water vapor into tiny droplets. Key factors include:
- Temperature: Cooling of air near the surface (e.g., radiative cooling at night or advection of warm air over cold surfaces).
- Humidity: High moisture content in the atmosphere.
- Particulate Matter: Aerosols and particles act as condensation nuclei.
2.
Solar phenomena like CMEs and other solar emissions can impact Earth's atmosphere in several ways:
- Geomagnetic Storms: CMEs can cause geomagnetic disturbances by interacting with Earth's magnetosphere, leading to changes in ionospheric conductivity and geomagnetic field fluctuations.
- Cosmic Ray Modulation: Solar activity influences the flux of galactic cosmic rays reaching Earth's atmosphere. These rays can enhance ionization and potentially contribute to cloud and fog formation via aerosol creation.
- UV Radiation and Ozone: Variations in solar ultraviolet (UV) radiation affect ozone production, which could influence atmospheric heating and cooling rates.
3.
While the mechanisms above can influence atmospheric dynamics, the connection to fog formation is not direct and would likely involve:
- Indirect Effects on Aerosols: CMEs might alter the production or distribution of aerosols through geomagnetic storms, which could affect condensation nuclei availability for fog formation.
- Regional Temperature and Pressure Effects: Solar-induced changes in atmospheric circulation could influence local conditions conducive to fog, such as radiative cooling or moisture accumulation.
4.
Studies exploring correlations between solar activity and lower atmospheric phenomena like fog are limited. However:
- Research has shown some correlations between solar activity and cloud cover, which could indirectly affect fog formation.
- A global analysis of fog events against solar activity indices (e.g., sunspot numbers, CME frequency) could help identify patterns.
5.
- Time Scales: Solar activity varies over short (solar flares) and long (11-year solar cycle) timescales, whereas fog formation is a local and transient phenomenon.
- Data Resolution: High-resolution global data on fog events, aerosols, and solar activity are necessary for robust analysis.
- Confounding Variables: Atmospheric fog dynamics are influenced by myriad factors (e.g., topography, urbanization), complicating isolation of solar activity effects. [...].
