Hi everybody! This is the first message I write on my Blog.
I'm writting about a really interesting phenomenon, that happened here in Greece (Thessaloniki) in August! It was a hot day with unstable weather, so I went to the flat roof to look for thunderstorms. And I noticed a Cumulonibus cloud North of Thessaloniki, which was "producing" small Cumulus.
While these Cumulus clouds, were getting closer to Hortiatis mountain, they were getting bigger, developing up to Cumulus congestus, as you can see in the picture.
But suddenly something strange happened! The Cumulus clouds were developing so rapidly, that they had already become a Cumulonibus cloud in 15 minutes!!!
The rain soon started under the Cumuloninbus cloud and some small mamatus appeared.
The funnel was getting larger and the whole phenomenon lasted 15-20 minutes!!
And another thunderstorm appeared North.
This funnel cloud may not excite someone living in USA, but phenomenons like this do not appear that often in Europe, but they can be a nice surprise, since accidents do not happen.
Video and time lapses!
