Why does the UAE get so foggy every summer? The science behind the seasonal phenomenon

## The Science Behind UAE's Summer Fog

During the summer months, the UAE experiences frequent fog, particularly in the early mornings. This phenomenon, known as radiation fog, occurs due to a combination of high humidity, desert conditions, and overnight cooling.

## How Fog Forms

Fog forms when warm, moisture-laden air from the Arabian Gulf and Arabian Sea moves inland. As the desert cools rapidly after sunset, the air near the ground also cools. When the air temperature drops to the dew point, water vapor condenses into tiny droplets, creating fog.

## Role of Geography and Dust

The UAE's proximity to the Arabian Gulf provides a constant source of moisture. Sea breezes carry humid air inland, where it mixes with dust and sand particles. These particles act as condensation nuclei, facilitating the formation of fog.

## Impact on Transportation and Health

Fog can significantly disrupt transportation, affecting road, air, and maritime travel. Visibility can drop to less than a kilometer, increasing the risk of accidents. The National Centre of Meteorology often issues alerts during foggy conditions.

Health-wise, fog can exacerbate respiratory issues, particularly for those with asthma or cardiovascular conditions. The cool, damp air may irritate airways and pose additional risks to vulnerable individuals.
