What are the main sources of fog in coastal regions?

The main sources of fog in coastal regions are typically related to the temperature difference between the land and sea. When warm, moist air from the ocean comes into contact with cooler land surfaces, it cools and condenses, forming fog. Additionally, coastal areas are prone to advection fog, which occurs when warm, moist air moves over a cooler surface, leading to condensation and the formation of fog.

What role does temperature inversion play in the formation of haze and fog?

Temperature inversion plays a crucial role in the formation of haze and fog by creating stable atmospheric conditions that trap pollutants and moisture close to the surface. During a temperature inversion, warm air sits above cooler air, preventing vertical mixing and allowing pollutants to accumulate. This can lead to the formation of haze and fog, particularly in areas with high levels of pollution or moisture.

Can haze and fog have an impact on respiratory health in humans?

Haze and fog can have a significant impact on respiratory health in humans, especially for individuals with pre-existing conditions such as asthma or chronic obstructive pulmonary disease (COPD). The fine particulate matter and pollutants present in haze can irritate the respiratory system, leading to symptoms such as coughing, wheezing, and shortness of breath. Prolonged exposure to haze and fog can exacerbate respiratory conditions and increase the risk of respiratory infections.
