What is the relationship between temperature and dew point?

The relationship between temperature and dew point is that the closer these two measurements are to each other, the higher the humidity in the air. Dew point indicates the temperature at which the air becomes saturated with moisture and can no longer hold all the water vapor it contains, leading to condensation. When the dew point is close to the current temperature, it means the air is nearly saturated with moisture, resulting in higher relative humidity. Conversely, if there is a large difference between the temperature and dew point, it suggests that the air is relatively dry with lower humidity levels. This understanding of their relationship is crucial for interpreting weather conditions and forecasting humidity-related phenomena.
