What cause the luminousity of the flame?
The color of the flame depends on the temperature, fuel nature, composition of particles in the flame, oxygen concentration.

What causes a Flame?
Rather than what the previous answer was, I believe the flame moves because of where the reaction is taking place. The combustion reaction requires oxygen as well and so where it feels an abundance of oxygen (small scale level), the reaction will follow -> which leads to the visual effect of the moving flame. Outside from that, many factors can affect motion of the flame, such as a draft from.. anything, and many more simple factors like such.

Closing the gas tap a little reduces the amount of gas flowing into the burner. This causes a reduction in flame.
What causes the luminescence in the cooler yellow flame on Bunsen burner?
The luminescence in the cooler yellow flame is caused by closing the air vents of a Bunsen burner. This is the result of incomplete combustion.
What causes the Bunsen burner flame to be noisy?
There are actually two flames that appear one is yellow & other is blue. And the blue flame makes more noise than the yellow.I think it is the sound of air rushing through the vents to get to the flame. The reason you get the yellow flame is that the gas is not burning completely. It is when you open up the vents that the flame is adjusted to blue.
