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.

What causes flame rollout?
insufficient secondary air
Why does closing the gas tap a little reduce the size of the flame?
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.
What causes a green line in the spectrum of selenium?
Probable an impurity; the color of selenium in flame test is blue.
What causes the luminousity of a flame?
Flame luminosity occurs because of lack of oxygen. Also, the air holes in the Bunsen burner affects the flame.
What causes flame rollout?
insufficient secondary air
What causes a burner flame to burn at the base of the burner?
because it's hot
What element often causes difficulties interpreting a flame test?
Sodium(Na)?
What causes a burner flame to be smoky and to separate from the tip of the burner?
If there is not a sufficient supply of oxygen, the flame will be smoky from excess of carbon.
When you cook spaghetti in water you have salted with NaCl When the water boils it causes the flame of the gas burner to turn bright orange How would you explain the appearance of a color in the flame?
The sodium turns the flame bright orange..

What causes sparking at the brushes in amotor?
It has static charges. Or it may be combustible, that's why it spark and went to flame.
What is the functions of air hole?
The function of the Bunsen burner air hole is to adjust the flame from a luminious flame to a non-luminious flame.So that you can choose if you want a dirty flame {yellow} or hot flame {{blue}}. The yellow flame is generally called dirty because of the amount of carbon it produces and it causes soot when it is heating something.For more information about busen burner,You can add Ruoyu Wang at facebook.He is a expert of this.
