Stormy Weather

[teamsaint]

That is Mammatus cloud, so called because of its resemblance to udders (Mamma), but to me resembling a maritime ice sheet seen from underneath. It often presages thunder, but not last night, as it happens.

There seems to be little known about what precisely causes it. Wiki has several photographed examples at the bottom of its entry:

Great knowledge as ever, S-A. cheers.

it was very impressive, and what I couldn't capture was that it seemed to be very localised. Immediately adjacent to the area of mammatus was some much more normal wispy/patchy summer cloud. a very odd scene, but very striking.

certainly no thunder associated with this .

[DracoM]

Yes, and worse since I last posted.

Not good here today. Just raining! :(

Well, from the amount of staying away from the thread, it looks as if the present weather pattern being likely to be maintained for the rest of the summer is generally accepted now, with the position of one day good, two in a row bad for Scotland and the north being reversed for the south, and amounts of rain averaging out across the whole.

It suits me fine, as it happens, as it minimises having to water the garden, and in any case I'm not good at coping with prolonged hot weather, but for others it's a disappointment, I know.

Just had this tablet delivered yesterday! Trying it out on here for the first time today!

Sunnyy and cloudy today

The weather in these parts has been "annoying to appalling" one way or another recently. You've probably all seen the scenes at St Andrews on Friday. What you probably didn't see was this, a few miles north as it's well known that little ever happens outside the south east of England.

Anyway, yesterday three of us went to the Open at St Andrews, and saw only about 90 minutes' play before we had to leave to get home. It was a beautiful sunny day, but play was stopped because of high winds. As I write it's raining here, so it's probably raining in St A as well. One way and another I'm not feeling well disposed to the weather at the moment.

It can't spell and has a logic error - send it back!

Believe it or not mangerton, the flash floods at Aylth were headline news down here! It looked like archive footage from the great January floods. I don't know what your average monthly rainfall is but here for July it should be around 55mm - we've had precisely 13mm so far mainly comprised of drizzle rather than downpours. The worse part of this strange weather pattern has been the wind, almost constant and gusting up to 30mph which of course immediately dries up the meagre rainfall. I don't know the explanation for the high winds or why it's always veering in direction. I fear I've wasted my money on my new, very chic, garden furniture as balmy evenings have been in very short supply and the evenings are already drawing in.

Either the tropics are warming up more or the polar regions cooling down more, leading to sharper temperature diffentiations where the respective outflows meet, which is where we (and on the other side New Zealand) roughly are; this in turn increasing the velocity of the jet stream, and consequently the vigour lf its associated low pressure systems. The latter certainly are getting much deeper and more widespread in compass than they used to be - we never used as frequently to get these huge lows occupying the whole of the N Atlantic, and hanging on, like we do now, and that would be explained by this phenomenon.

Thank you as ever SA for your illuminating posts! :)

What irks me is the forecasters nonchalantly asserting that yesterday was 'a bit breezy'.
It was a heck of a lot more than that oop 'ere, I tell thee.
