Cumulus Support

hi

Cumulus has been displaying "Stormy, much precipitation" a lot recently, over the last two / three weeks.

This may be because it's been stormy with much precipitation; as British regulars here will know we've had a series of explosive cyclogeneses and other Atlantic low pressure frontal systems coming over. Or is it an error? Some configuration error?

NB: the "Pressure extremes: low" setting is set to 960mb so it doesn't say "Exceptional Weather, Stormy, much precipitation" - just "Stormy, much precipitation".

Thank you!

Doug

I think it's simply that it's the forecast that the algorithm comes up with in weather like this. I checked a few other sites from Fine Offset users, and they all had the same forecast. It does seem like a pretty reasonable forecast at the moment!

Thank you! Yes, it's pretty accurate!

Doug, it's the opposite really isn't it? What is the best way of describing something that is deepening extremely quickly? Imploding doesn't seem right.

I think "Explosive Cyclogenesis" is the usual term?

It is Steve from those links but logically it still looks like the wrong term to describe something that is not expanding outwards rapidly. Bombs explode, black holes implode. But I accept that's the official term.
