The greater the difference between the wet bulb and dry bulb temperatures, the drier the air is because the wet bulb temperature represents the lowest temperature that can be reached through evaporative cooling. The relative humidity is lower because the greater the difference, the more water can be taken up by the air through evaporation, meaning the amount of water in the air is lower compared to what it could potentially hold.
