Guys that really know the stuff
RE: Windy model updates
ECMWF data are not free.
Windy already pays a lot for ECMWF 00Z and 12Z runs
and provides those datasets to us with no cost and ads free.
Beware of the Cumulonimbus capillatus
As the last low-level cloud species will be Cumulonimbus capillatus (Cb cap), which is a really huge storm cloud. It is still counted as a low-level cloud because its base is usually below 2 km hight, but its top can reach 15 000 km (in extremes even 20 000 km). So, how does it look like, and why should we be careful?
Cumulonimbus capillatus looks like an anvil because it has a wide top which looks like a hair. And a word "hair" in Latin is "capillatus"! It sometimes remotely resemble a ruffled hair on a cloud, which can be long through all of the clouds. It is a nice look at it, but only from a distance.
When it comes to precipitation, Cumulonimbus capillatus rarely causes showers. Usually, it makes heavy rain, thunderstorms, strong wind and hail. For all this, it is one of the most dangerous clouds you can spot in the sky!
Cumulonimbus is more likely to occur in summer and in some cases it comes with a cold front, rarely with a warm front.
Watch out for the Cumulonimbus capillatus and send your photos!
ECMWF (the best is yet to come)
A change in the Integrated Forecasting System (IFS) planned for June this year
will enable ECMWF to use more up-to-date weather observations
to help define the initial conditions for its forecasts.
This shift towards more continuous data assimilation
will significantly improve the quality of forecasts,
which depend on the accuracy of the initial conditions.
