I can only answer with this, it's not going to answer your question fully, but i hope it helps, (Unless you already knew this)
As temperature increases, the air becomes less dense, thus needing a higher speed to get of the ground.
It works the other way around in cold temperatures.
Temperature decreases, Air Density increases, Lower T/O Speed.
