Well, if we want to improve our chances to become 100 (or even 110) years old, we should maybe stop such a dangerous activity as paragliding...
Corinne and I got in some surprisingly excellent soaring here in Switzerland. Check out the picture
Except for the beautiful wing, it doesn't look especially nice, does it? It's grey and overcast, with a dense layer of fog. The lowlands in Switzerland often suffer from such weather in winter. It's a sea of unstable and cold air which gets trapped under an inversion and beautiful weather above. However, this situation has good things to offer for us. First, the flying. Under the inversion, there are often quite strong northeasterly winds. So we went to this low site, it would be around 700ft vertical if you flew all the way down, but nobody does it. If you sink out, you land on the hillside just below launch and kite the wing back up. We got there, stood on packed snow and the wind was blowing with steady 12-13mph. We jumped into our harnesses and what followed was really cool. Like at the Point of the Mountain, endless soaring, playing around, touch and go's, skimming a few feet above the ground, etc. Optimal, to get to know a new glider. Surprisingly, there were thermals. You wouldn't believe it. It was cold, snow covered and without a single ray of sun. But clearly defined thermals, with at times lift of up to 600fpm! I don't know where they came from, but it must be the extremly instable air mass below the inversion. I even went to "cloudbase" around 500ft above take-off. We flew (and played) for more than 1.5 hours, then landed, visited the nearby restaurant to warm up and flew (and played) for another 1.5 hours. Almost like Torrey Pines in this sense...
So, there's a second advantage of this weather pattern. Above this fog layer (and the inversion), the weather is splendid. Warm, sunny and totally calm. Perfect weather for skitouring. Check out the following picture and see Corinne climbing above the valley of Engelberg, also a very good place to fly in spring and summer. You can also recognize the inversion in the valley below, although there is no dense fog here - it usually doesn't move all the way into the alpine valleys.
Cheers,
