Thermal Inversion

If you’re like me, you might read “driving to the sun” and think I’m speaking of driving to Spain or to Southern France. This wasn’t the case today. Today, as I saw we were in the fog, or in a layer of cloud I decided that I would drive up to an island above the fog. The island, in this case was Pampigny.

You might say “but Pampigny is a village on a slope, not an island. You’re right, of course. Today though, it was an island. If you looked towards the Léman you saw low lying clouds until the Alps, and if you looked towards Neuchatel then you also saw clouds.

Thermal inversions are a great part of life in valleys. Whilst you’re living down in the glacial trough you’re waking up every morning to the knowledge that you won’t see the sun for the next few days… until the wind shifts. If you’ve got the time during daylight hours though you have the option of going up to the mountains. It’s at this point that you can enjoy the sun. As you walk in the Jura at the moment you’ll find that there are long plaques of ice and they’re slippy whilst in direct sunlight. In the shade traction from normal shoes is possible and walking is not that complicated. There are different types of ice, that which is transparent, where you see the leaves and other objects, that which is white, from too much oxygen and then the mixture where it’s a little of both. Many families were walking today, some were struggling and others treated the landscape like a giant playground. Some people spoke French, others, German, Italian, Spannish and more. It was international. Sometimes when I walk there are hardly any sounds and it’s good, a break from London and student life.

It’s the night before Christmas day and it’s been relaxed. With the thermal inversion it’s easy to get above the clouds, simply get in a car and go to the mountains and you’ll get a nice view of the sunshine. We went to the vallée de Joux and that’s where you find many of the watch factories. This includes Audemars Piguet amongst others. Tomorrow’s Christmas day, then 6 days till the new year.
