The ground's warmth creates a upward convection current of air which refracts the distant lights we see as "twinkling."

The twinkling effect seen with lights are usually due to atmospheric disturbances, which creates temporary pockets of air that can diffract the light. But if some cities have low atmospheric disturbances, usually pollution or moisture, the light is less diffracted, thus does not twinkle.
