When skydivers jump together, the gravitational potential energy they possess is converted into kinetic energy as they accelerate downward. The air surrounding the skydivers is not directly affected by this conversion of energy, so the overall effect on the air temperature is negligible.
The change in gravitational potential energy of the skydivers does not directly cause a significant increase in the thermal energy (internal energy) of the surrounding air particles. The gravitational potential energy is primarily converted into the kinetic energy of the skydivers' motion.
However, it's worth noting that when skydivers descend rapidly, they can create disturbances in the surrounding air known as "wake turbulence." This turbulence can mix the surrounding air and potentially cause localized changes in temperature. However, the overall effect on the ambient air temperature due to the motion of a few skydivers is minimal and quickly dissipates as the air returns to its equilibrium state.
In summary, while the motion of skydivers can create local turbulence in the air, the conversion of their gravitational potential energy into kinetic energy does not significantly impact the overall temperature of the air. The air temperature is primarily influenced by other factors such as solar radiation, atmospheric conditions, and large-scale weather patterns.
