Time-lapse of the local storm that developed in part of the Teide National Park on August 25, 2017.


The effect of daytime heating on the Cañadas del Teide, in an environment of thermal instability by warm African advection at low levels, triggered the convective development of high base clouds that grow vertically until they develop anvil-shaped cumulus producing precipitation and some lightening storm in a small area of ​​the Teide National Park, next to the volcano.

Some thermal instability in medium levels is observed by the warm advection at mid-altitude, without dynamic forcing nor much humidity available causing a high condensation level, above even Teide peak. The radiosonde showed a stratum above the temperature inversion with a practically adiabatic gradient. However, it is surprising that the convection reaches enough level to produce lightning storm.
