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.
Pressure is not a fixed value; rather, it varies with environmental factors, such as altitude and temperature. Atmospheric pressure is also known as barometric pressure or air pressure. Simply put, it is a force exerted by the weight of the atmosphere pushing down on a given area. The standard pressure on earth at sea level is 101.325 kPa by definition. However, different climatic conditions will change the air pressure of different regions. Temperature changes will cause changes in air pressure.
