Fascinating fog facts to impress mini meteorologists
1 of 11 WHAT IS FOG? Fog is a type of low-lying cloud made out of tiny water droplets. It is different from clouds because it is closer to the ground rather than up in the sky, and it is different from mist because it is thicker and makes it harder for you to see (by definition fog reduces visibility to less than 1km, whereas you can see through mist more easily).

2 of 11 WHY DOES FOG HAPPEN? Fog forms when the dew point and the air temperature difference is less than 2.5 degrees C. It begins to form when water vapour condenses into tiny water droplets that stay hanging in the air. It happens in the UAE when cold winter weather like we are experiencing now is coupled with high humidity levels close to 100%. When this is combined with wind speeds no higher than 5km/h and high-pressure cooling of the Earth’s surface, you get
