Dew point is the temperature at which the water vapor in the air condenses, then evaporates. The barometric or air pressure is independent from the dew point.
Dew point temperature is the temperature at which air becomes saturated with moisture and dew forms. As pressure increases, the air can hold more moisture before reaching saturation, leading to a higher dew point temperature. Conversely, a decrease in pressure lowers the air's capacity to hold moisture, resulting in a lower dew point temperature.
The dew point is a measure of the amount of water vapor in the atmosphere. As the temperature gets closer to the dew point, the humidity rises. When the temperature finally drops to the dew point (100% humidity), the the atmosphere is completely saturated with water, and it will start to rain (or snow, if the dew point is below freezing). Since the atmosphere is completely saturated when the temperature is at the dew point, it cannot go below the dew point.
The temperature at which moist air becomes saturated and forms dew is called the dew point temperature.
The symbol for dew point temperature is usually represented as Td.

The relationship that you expect to find between the air temperature and dew point temperature at ground level if the area is covered by fog is the temperatures of th air and the dew point would be very close in value.
The relationship between dew point and pressure is that as pressure increases, the dew point temperature also increases. This means that at higher pressures, the air can hold more water vapor before reaching saturation, resulting in a higher dew point temperature. Conversely, at lower pressures, the air can hold less water vapor before reaching saturation, leading to a lower dew point temperature.
The dew point is the temperature at which air becomes saturated with moisture. When the dew point is below freezing, frost can form on surfaces as the moisture in the air freezes.

Condensation occurs when air reaches its dew point, which is the temperature at which air becomes saturated with moisture and can no longer hold it in gaseous form. When air cools to its dew point, water vapor in the air condenses into liquid water, forming dew or fog.
The main difference between frost point and dew point is the temperature at which they occur. Frost point is the temperature at which water vapor in the air turns directly into ice crystals, while dew point is the temperature at which water vapor in the air condenses into liquid water droplets. Frost point typically occurs at colder temperatures than dew point.
Dew point temperature is the temperature at which air becomes saturated with moisture and dew forms. As pressure increases, the air can hold more moisture before reaching saturation, leading to a higher dew point temperature. Conversely, a decrease in pressure lowers the air's capacity to hold moisture, resulting in a lower dew point temperature.
When dew forms in the winter, it forms at night and its colder at night so the dew freezes at that point in freezing.
The dew point controlled the temperature of the air.
