Inland, western winds as usual in the morning, but they seemed to be stubborn and didn't want to give way to the more eastern winds heading from the coast. Later on plain eastern winds, great for the cliffs. I told you last week, we were gonna have an excellent week of flying , and we do. I think our buddies from up north could fly on Col de Rates. That's probably were we should go tomorrow. Or Agres, or Monte Cabrer, or Sant Antonio, or Hondon north, even La Zafra could be working.


For those who are interested in some meteo next images.
Images comparing the jetstream maps with the isobarmaps.
Jetstream flows are present on high altitudes lucikly, approximately 10 km above us.
Due to the curves in the jetstream, some of the air is pushed together from various directions. This 'converged' air, results in an increase of the weight of the air on our surface, results in more pressure on our planets' surface, meaning higher pressure. That air is descending, so pressure is increasing. Very obvious to see on these maps.

But, action an re-action. Under some other parts of the jetstream the air is dispersing, going in different directions, causing lower pressure, causing cloud formation. The effect of this on our planets 'surface, is causing fronts. In combination with our satelite images, we can easily spot where these fronts are situated. We hate them don't we.
