The Summer Factor: Temperature. Temperature also affects density altitude. When you heat the air, the air molecules have more energy. And, when they have more energy, they spread farther apart. (You probably learned this in high school chemistry class...). When the air is warmer than standard, it's less dense and performance decreases.
Mrs. Deringer's Air Pressure-The force with which air presses down on the Earth Believe it or not, air takes up space, has mass and weight. Air pressure is affected by three factors. H. A. T. The H stands for Humidity. As the Humidity increases air pressure decreases. That means as the amount of moisture in the air increases the air pressure decreases. The A stands for Altitude. As the altitude increases the air pressure decreases.
