Here's why:

* Temperature is a measure of the average kinetic energy of the particles in a substance. Kinetic energy is the energy of motion. The faster the particles are moving, the more kinetic energy they have, and the higher the temperature.

* Air particles are constantly in motion, colliding with each other and with the walls of their container. This constant motion is what we perceive as heat.

* The faster the air particles are moving, the higher the temperature. This is why we feel hot when the air particles are moving quickly, and cold when they are moving slowly.

While other factors can influence air movement, like wind speed, temperature directly reflects the speed of the individual air particles.
