Low Carola came very close to passing directly over the weather buoy K1 this lunchtime by the look of the visible satellite image (fig 1) and the plotted observations (fig 3).
The gradient ahead of Carola was very tight, but it was even tighter behind it, with K1 reporting storm force 10 northwesterlies with a mean speed of 53 knots with gusts to 70 knots at 14 UTC – now that’s what you call a storm!
Low Carola is deepening very quickly at the moment, and the curl of cloud she is spinning up makes an impressive site in the latest satellite imagery to the southwest of Ireland (fig 1), as do the plotted observations and barograph from the weather buoy 62029 better known as ‘K1’ (figs 2 & 3).
As far as I can see Carola easily breaks the barrier for rapid cyclogenesis of 24 hPa in 24 hours, the pressure there has fallen by 37.4 hPa in 12 hours, in fact I don’t think I have ever seen sustained pressure falls like that on a chart from an extra tropical low.
No doubt the French will have claimed this low and come up with their own name for it, but I noticed it didn’t even get a mention in the BBC forecast at 12.58 pm from Sarah Keith-Lucas.
Rather more geographical than meteorological I know, but I think I’ve identified these four snow-covered mountain ranges in Spain which are standing out so well on today’s satellite picture (fig 1). I reckon that after a bit of research they are:
The snow-covered mountains close to the south coast are of course the Sierra Nevada’s or ‘snowy mountains’ in Spanish, which for some reason I had always believed lay further west. The highest point is Mulhacén at 3,478 metres which is also the highest point of continental Spain.
An interesting satellite picture day of clouds across the bay of Biscay from the NOAA Worldview website (fig 1). If anything, the grey scale image from the Met Office taken a little later looks even better (fig 2). As far as I can tell it all looks like a sheet of low stratocumulus cloud at under the anticyclone, with a cloud base of around 4,000 feet, but I could be wrong.
A great visible satellite image of an almost cloudless Scandinavia covered in a winter mantle of ice and snow. Part of the ice in the northern Baltic seems to have been become detached from the shore due to the recent strong northerlies, and has opened a clear patch of water.
Strange goings on in the Sahara desert south of Cairo (fig 2).
What looks like medium level altocumulus, but’s probably a much lower sheet of stratocumulus to the north of the Canary Islands (fig 3).
