The discussion centers on the phenomenon of relative humidity dropping below 100% despite the presence of moisture condensation. It highlights that once the dew point is reached, moisture continues to condense due to an imbalance in partial water vapor pressure. The conversation also addresses how rising atmospheric temperatures can increase evaporation rates, leading to lower relative humidity levels, particularly in scenarios like humid air over hot, dry pavement. This results in air temperatures exceeding the dew point, as evaporation occurs at a slower rate than boiling.
PREREQUISITESMeteorologists, environmental scientists, and anyone interested in atmospheric science and humidity dynamics.
For example, humid air over hot dry pavement -- you have an increase in temperature with no additional water vapor being added to the system. Relative humidity decreases and the air is now hotter than the dew point.wasup23 said:How is it that once the dew point is reached, moisture continues to condense. What is causing the imbalance of partial water vapor pressure?
Does the rise in atmospheric temperature simply pass up the evaporation rate too quickly?
