Trolley 679

Trolley 679 captured in the ramp down to the Kokoro Passage from Station Approach. Another M&S trolley returned to their food hall.

PS 1: this typed towards what looks to be the end of a nocturnal thunder storm, at least nocturnal thunder, lightening and rain, if not quite a storm in insurance speak, which distinction I read at reference 2 can be important. Cover for storm yes, cover for bad weather no. So all quite important if your holiday camp has just been washed away by flood following rain. Plus the lightening was much more impressive in the dark than it has been by day in the past.

PS 2: I remember once, when we were very young, staying in a camp site near St. Tropez. A camp site which had been carved out from around a river which was subject to flash floods when there was rain in the hills behind. There having been such a flood a few days before we arrived: dried out but with a fair amount of mud spread about. From where I associate to all the council estates built in this country, in such places, after the war. Cheap, vacant and available land I suppose.

PS 3: a little later: for these purposes storm or not is a binary dichotomy - which it is not. The rule might be whether or not the weather system in question has been given a name, but maybe the vagaries of Met Office bureaucracy in this matter are not a strong enough peg on which to hang serious money? Maybe, if one goes into the physics of it all, one could find a phase change which does yield a dichotomy. Enough heat in the thunder clouds for bubbles of steam to form? A sudden shift in temperature and/or pressure? But even then, converting that generality to observed facts from a particular time and place that a barrister could argue to in court, might prove tricky.

PS 4: in which connection, I might say that Gemini did a good job on explaining where the energy that goes into lightning comes from, that is to say from the sun heating up moist air close to the surface of the air, moist air which then rises. It was not so good at wrapping this up into a neat and tidy story, but it chuck out enough clues that I could do that bit. And it may be that the clues were not terribly accurate in detail, but I have not checked that.
