| You are flying at 2000m AGL on a great xcountry day in the Highveld. And you got a nice 20 km/h wind pushing from the back. You notice in front, about 1 km ahead, a line of lower clouds developing 1000m below you. Behind that line is no more high cloud. As you approach you have hardly any sink, even some very light lift. Suddenly you are in for some rock and roll. As you cross over that lower line of clouds you loose your glider. After a while you find your glider again in front, or below you, while doing a nosedive towards the ground. Once you rearrange your environment again, that the blue is above and the brown is below, you notice that the 20 km/h back wind has become a 30 km/h headwind. What did you cross through? What is the meteorological term for this? | |||
