the colder it is the less kinetic energy the air particles have, making them closer together, and able to vibrate and transfer sound better.
but ive been wrong before. thanks meteorologist guy.
it prob. has somthing to do with density of air and the amount and spacing of other particals the sound has to travel thru.
It is just the opposite to what you have said. Sound velocity depends upon the absolute temperature and the wind speed. Therefore sound travels faster in warmer air, and when blown by a tail wind.
Definitely better in warm air. It is also ductable, such as on a foggy still lake where the thermocline in the air can cause a sound duct along the surface, and you can hear people miles away talking in regular voices.
