Does this mean government seeding has worked?

I hope it rains until September and Bangkok floods for several months because they said floods like 2011 can never happen again as they spent 400 million Baht on a new wall as far North as N/Sawan, so lets see how good it is.

 

Anyone seen this wall out there that cost all that dosh ?

I've seen bits of wall, but don't really know how it is meant to work.  A certain area just norf of BKK still has lines on walls from the last one.  Now I see near a temple a wall has been built, they spent a long time driving posts into the water, and a single layer of bocks to make a wall.  but then it stops.

my question is what about if the water decides not to attack from the river at that point, but comes in from behind ? you know decides to jump out of the river at an earlier point .

of course that won't be considered,

 

I guess this is the buddhist way? or the thai way?

That is correct. Saturated air, even air at nominal ambient conditions has a mass mostly due to its moisture content. Then we could talk about density relationship to enthalpy but the variables are never ending

Jump to Impact on air density · Water vapor is lighter or less dense than dry air. At equivalent temperatures it is buoyant with respect to dry air, whereby the density of dry air at standard temperature and pressure is 1.27 g/L and water vapor at standard temperature and pressure has the much lower density of 0.804 g/L.

And enthalpy has got to do with chemical reactions at a constant pressure. Yet to know about chemical reactions in weather systems.

Anyway, has anyone anywhere had heavy rain and storm conditions in their local area?

Edit.

Thanks for the figures 1.27 and .804. I couldn't remember exactly. Think I said 1.3 and 0.7, but close enough.

I suppose that depends on how much rain there is. ???

Sorry

There'll be plenty of it,..... if the BKK floodings started soooooo early this year. I have something like a sixth sense for that. Trust me.

I think Sakhon Nakhon had a big storm yesterday. But where i am in Udon, it has only really rained once since October (i'm not including the odd spots which never even settle the dust), driest i have seen in 10 years.

Sorry for having started this, 'overherebc', but you came up with such a theory, which could have even irritated Mr Newton and his apple. Great stuff you wrote, but, but... Let me stick to basics, as I won't spend the evening debating about straight forward common sense things. It's just that some Thais with a good knowledge of English, and a taste for sciences, present on TV (really a few then?) might be getting it wrong because of you. OK, then let's go (but let the winds out of this a-b-c basic, and the influences of electricity):

- 'basic' air (the combination of gasses we breath, N and O, and the rest) is made of very light (specific weigh), and highly compressible molecules, while water (the tainted H2O in nature) consists of quite heavy molecules, and hardly compressible, pressure, yes, you get it already;

- in high(er) pressure zone, the air contains less to little water droplets (there is no such thing in nature as air without any moisture %), and is easier to compress (by natural forces), the higher the pressure the lesser water droplets in the air, so 'ascending' away from the surface;

- a low(er) pressure zone is an area where the air contains more to a lot of water droplets (100% 'moisture' is still not same though as being in compact water), the lower the pressure the more, and the harder to compress;

- 'light' (dry-er) air 'climbs' easy(ier) (partly because of its very low specific weigh);

- 'heavy' (wetter) air does raise to though, but with a structure change: look at fog f.i., myriads of very tiny droplets, so numerous the density, and the weigh, are so high this cloud formation hangs very close to the surface. At the other end of the scope there are the cyrrus, the highest clouds, containing a very light concentration, ...of the heaviest form of water (ice crystals). In between are all kinds of clouds, all also holding water, most from the evaporation of surface water, ...in different forms. The warmer these waters, the higher the quantity evaporating = going up in the air. Going up in the air, this moisture mixed with air is exposed to lower temperatures (well, not always, but...) which has the effect of condensating these water droplets, grouping them, and making them heavier, till at a point saturation occurs, where the weigh of drops becomes too high to stay in the air, ...and the drops fall down as raindrops, small or big, few or a lot (or snow or hail).

The mix of the previous, known to us as 'weather' is another chapter, I'm ready to pass through to you too 'overherebc', when you really want, but not today.

It was great teaching such things to (interested) pre-pubes and teens, where are the days?

Still waiting for you to prove any of the above which is completly confusing. Never rained apples anywhere I've been.  ??

It means you are incorrect. Unless we are talking about superheated dry steam which is highly unlikely unless produced under extreme pressures.

 

No, it is you that is incorrect, water vapor molecules are lighter than oxygen and nitrogen molecules, and considering Avogadro's law, which states than equal volumes of gas at a constant pressure and temperature contain an equal number of molecules, it is clear that air with water vapor in it will be lighter than air without.  Where did you get the 600 number from, your ass?

Heavy rain near Cha-am at the moment,already over 40mm so far today.

Early this morning a smaller shower but this one is really pouring down.

Google windty.com

Gives you a good idea of what's going on. You can check wind rain wave conditions etc.

Sorry   windy.com
