Our weatherman Aidan clears up the facts about fog

He's been to Bedfordshire to talk to scientists involved in the latest research on what causes fog and how it can be predicted more accurately.

And here are ten facts about fog from Aidan

  • The difference between mist and fog is how far it is possible to see. The airline industry define fog as visibility less than 1000 metres. The civilian definition of fog is when visibility is less than 200 metres.
  • When fog occurs and the temperature is below 0ºC, it is called freezing fog.
  • Rime occurs when the water droplets in fog freeze onto the outer surfaces of objects, giving everything a frosted covering.
  • Smog is a type of air pollution made up of smoky pollution and fog. The worst smog to ever hit the UK was the Great Smog of 1952, which wreaked havoc for four days in London. This led to the Clean Air Act of 1956.
  • Vog occurs when volcanic gases such as sulphur dioxide react with oxygen and moisture in the atmosphere under direct sunlight to give a volcanic fog. It is common in Hawaii.
  • Fog is simply another type of cloud: a stratus cloud that sits on the ground
  • The foggiest place in the world is the Grand Banks off the island of Newfoundland where the cold Labrador current from the north meets the warm Gulf Stream from the south. The water vapour that accompanies the Gulf Stream cools quickly and condenses, forming fog.
  • In the Atacama Desert in Chile, one of the driest places on Earth, fog is harvested from the air - using mesh-patterned nets to collect its water droplets.
  • The Fogstand Beetle in the Namib Desert stand still in the fog and allow the water droplets to condense onto their body, which they then drink.
  • Titan, Saturn’s largest moon, is the only object other than Earth in the Solar System known to have plenty of liquid on its surface. It is also the only other object to have patches of fog, albeit fog made up of methane and ethane.

The new boss at the East of England Ambulance Service says response time targets are unrealistic especially in rural areas.

Robert Morton joined the service this week and has more than twenty years experience - most recently in Australia.

He'll have quite a task to boost staff morale at a time when many say they're expected to work dangerously long hours.

Just today, he met union officials concerned about the fees student paramedics have to pay.

Norfolk born brothers Tom and Ben Youngs are both included

“It’s really positive that we have such depth and options to choose from. Selection wasn’t easy and it is tough to leave anyone out but it’s important to stress that the players not in this group are still part of our wider squad and could come in at any point."

– England Head Coach Stuart Lancaster
