Description: On a quiet July evening, suddenly a damp NW breeze rare in this area raised the alarm. So I climbed the northern area of the Iberian mountain system. Both the wind speed and the dampness increased with convection cloudiness favoured by the orography. And, after a huge development a mesocyclone had arisen with anticyclonic rotation, which included pannus. It moved to the river valley of the Ebro with absolute beauty and harmony.
