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.
Atmospheric pressure changes because where the sun heats the earth, the warm air rises and that reduced the pressure. Where cold air sinks, it increases the pressure. The wind is simply the air trying to balance the pressure between those two systems.tmospheric pressure changes because where the sun heats the earth, the warm air rises and that reduced the pressure.
