Norwegian Cumulonimbus (photos)

September started with quite good weather, but plenty of showers were interrupting the sunshine.


Some dark clouds were also getting closer, where I also heard only one rumble from!





Thunderstorms in Norway are really irritating. It's the only place, where almost all of Cb clouds I've seen this summer have made only one rumble heard each! The max number of rumbles I've heard this year is about 10-15 and unfortunately not at night... It's some years now since the last time Southern Norway experienced thunderstorm with many thunders...
After sunset, the Cumulonimbus clouds are often being transfered over the sea in Norway and that was obvious on 3rd September.



And new Cumulus were following, also growing up to Cumulonimbus after a while.


A “dead” Cb was getting closer from West and it was still able to give some rain.


This happened the perfect time, because a wonderful rainbow was created!


And the combination of rain and sun was so strong, that a second rainbow appeared above the first one!


The night was about to come, but before this, the Cb clouds made a spectacular view having this pink color.




When the sky got darker, I was looking for Cbs to find out if they do have electrical phenomena. Well, I observed this Cb cloud...


...but there was no lightning to see in it, except of the flashes I noticed coming from some clouds close to it, but there were only 2-3 of them again...

There weren't many Cbs to see next day, but lots of Cumulus clouds coming from the sea were giving also lots of showers. So, the weather was both sunny and rainy.





Some Cu appeared unexpectedly in the evening, but they were too weak to form any rain.


About ten days ago, early morning, a thunderstorm passed over Arendal, but-as unlucky I always am-the rumbles could be heard after it passed the area I live in... There were some louder noises this time, but there were not more than 10-15 of course... The cloud basis was indicating the unstable atmosphere.



And these were the only interesting clouds till today. After that day, the clouds were really boring and made you feel derpresed....
It's also cold now. When the sky is cloudless, the temperature goes down to 5oC at night, already now, in September...
Well... have a nice winter and plenty of snowfalls, then... Thunderstorms have to wait some months now...
