The dew point temperature is an indicator of the amount of moisture in the air. The closer the dew point is to the actual air temperature, the higher the relative humidity. In Toronto, the large difference between the air temperature and dew point suggests lower relative humidity than in Whitehorse, where the temperatures are the same. However, warmer air can hold more water vapor than colder air, so despite the lower relative humidity, the total amount of water vapor is actually higher in Toronto due to its much warmer air temperature.
