Summer - Afternoon 017

There is some energy in the air today. In the distance there are some cirrus clouds. Cirrus clouds are like feathers, they are high clouds, forming at about 9.000m (30.000ft). On the lower level, there are some developing cumulus clouds, which indicate the energy in the air. If there would me enough energy, they will evolve in cumulonimbus clouds, which can produce lightning.
