I am not surprised that this orb is affecting the clouds around them. I have photographed these not moving as in this video but with still pictures. I have also seen these in Google Earth looking down from above them and they bend the light around them which suggests they somehow warp space-time around them or change the refractive index of the atmosphere surrounding them somehow. I also know someone who photographs them at night from Vancouver BC, Canada, and that person has an infrared camera. They glow brightly in the infrared. Heating the surrounding air would have the effect of allowing it to take up more moisture evaporating the surrounding cloud water droplets.
