Remember, dew point simply is the temperature that the air would have to cool to in order for moisture in the air to condense into water droplets (forming dew or clouds). Humidity on the other hand is the ratio of moisture in the air compared to how much it can hold. This is dependent on temperature, so we'll stick with dew point as it easier to see a seasonal shift. In essence, the higher the dew point, the more moisture that exists within the atmosphere - however, dew point cannot exceed air temperature and is dependent on air p . Colder air simply cannot hold as much moisture, so there is less available to condense and form clouds (think of polar deserts like Antarcticat). When you hear of dry heat, that often is associated with warm, dry air, meaning a large difference between temperature and dew point. When that begins to change, and dew point increases, it feels humid and uncomfortable, and you are more likely to have rain and storms. Changes in dew point are one of the driving features for the change in precipitation and lightning strikes across | the southwestern United States during the summer, as the North American Monsoon becomes more prominent. “ o Monthly climate data for Flagstaff, Arizona can be found below. | Monthly Air Temperature 3 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov De : °c 1.7 2.8 4.4 72 11.6 183 19.4 16.6 15.0 10.0 3.9 0.t I O 351 37.0 39.9 45.0 52.9 64.9 66.9 61.9 59.0 50.0 39.0 33 | v Monthly Dew Point Temperature 1 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov De 4 °c 9.4 -5.0 -6.1 -5.6 3.9 -39 10.6 1.1 10.0 2.8 -5.6 -3; °B 15.0 23.0 21.0 220 25.0 25.0 51.0 52.0 50.0 37.0 22.0 25 Monthly Precipitation Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov De mm 51.0 53.0 51.0 33.0 35.0 12.5 122.0 1320 66.0 355 33.0 46 in 2.0 2.1 20 1.3 14 05 48 52 26 14 13 1t Study Area Lightning Strikes Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov De k = Count 0 0 10 25 25 10 3200 3500 500 10 0 0 . - e - f .
