Not that they join an already formed dual in the circuit. Anticyclonic will be extracted!

You can guess what happens next.


A volcanic eruption is going to brew up late Saturday. I think that we should be looking for where but have no idea past the line-out the air masses make on NA-EFS maybe where the cold hits and the emf?

How about Central America?
Always a favourite.
How easy will it be to back-track through Central American connections to trace electromotive force upsets?

It will follow these whatever:

Eight SW Pacific 26.6 S 163.7 W 35 kts TS

Look out when they become tropical depressions.
Any volcanoes near this:

Hmm! https://www.youtube.com/watch?v=jT1vRVOswMc

The North Atlantic gets really weird towards Friday and ends witha dual off Norway. Nothing especially extra ordinaey with twin cyclone cores though....
Is there?

I suspect we finally get a derecho in North America.

Out in the rain this morning it didn't look like more than drizzle but with the wind I was soon soaked. It isn't haw much water is in the air it is how much air is in the way. This stuff had teeth in it.

The thing is; if you know it you show it. Anticyclones are there for a reason. They haven't much power to develop the weather but they exist to pull it back in any direction they choose.

This occurs because Lows are too powerful to dwell anywhere for long and tend not to expand the same way that anticyclonic stuff behaves.

Never-the-less Atlantic cyclones can at times extend out all the way from Greenland to Norway. But at the moment a different proble one of syntax bothers me:

"The great quantities of dense water sinking at polar ocean basin edges must be offset by equal quantities of water rising elsewhere.

Note that cold water in polar zones sink relatively rapidly over a small area, while warm water in temperate and tropical zones rise more gradually across a much larger area.

It then slowly returns poleward near the surface to repeat the cycle. The continual diffuse upwelling of deep water maintains the existence of the permanent thermocline found everywhere at low and mid-latitudes.

This slow upward movement is estimated to be about 1 centimeter (0.5 inch) per day over most of the ocean. If this rise were to stop, downward movement of heat would cause the thermocline to descend and would reduce its steepness."

https://en.wikipedia.org/wiki/Thermohaline_circulation

Here is the crux of the matter:
"If this rise were to stop, downward movement of heat would cause the thermocline to descend and would reduce its steepness."

What downward movement of heat are they talking about?

During a cloudy spell, when hurricanes form (due to all that sunlight) the ocean temperatures can reach a magic 29 to 30 degrees C. (above zero for anyone beguiled by the CC idiocy.)

When this warm water evaporates it does so in a column forming the hurricane eye. The salt drops out and falls back into the front of the track leaving a stream of warm brine that is still falling.

Is this what the article has changed to study?
or are they still discussing the warm salt water that is falling in the Arctic?

Is the article purposely misleading or am I being obtuse?
Surely the salt that falls back is now a lot cooler than it had been despite the fact (or rather because of the fact) that the water has evaporated?

In the Southern Ocean, katabatic (falling) winds from Antarctica onto the ice blows newly formed sea ice away, opening polynyas (holes) along the coast and cools the ocean.

Sea ice reforms thus surface waters get saltier, Sea ice increases salinity; pure water frozen preferentially.

Salt lowers the freezing point; cold liquid brine is forms inclusions with an honeycomb of ice.

The brine progressively melts the ice beneath , eventually dripping out the matrix and sinking. This process of brine rejection could take ice down some way?

At what percentage is the matrix going to submerge. And how badly furquetted is the data?

Anything stronger than 37 grams of salt per litre would do it in ordinary ocean brine. Obviously if it lying on salty stuff it will stay afloat longer.

There again I doubt very much that anyone has measured the ash content form all the volcanic activity we have been having lately.

Stoopid is as stoopid does. I will have to go and ask the flowerpots.

The continual diffuse upwelling of deep water is a three dimentional rotation similar to the more easily depicted ocean gyres of surface patterns.

Except that: This slow upward movement is estimated to be about 1 centimeter (0.5 inch) per day over most of the ocean.
....and can't possibly be displayed on a chart

We now come to what went wrong with this discussion. The authors dropped on what logic presumes to be all there is to it:

"The dense water masses that sink into the deep basins are formed in quite specific areas of the North Atlantic and the Southern Ocean. In the North Atlantic, seawater at the surface of the ocean is intensely cooled by the wind. Wind moving over the water also produces a great deal of evaporation, leading to a decrease in temperature, called evaporative cooling. Evaporation removes only water molecules, resulting in an increase in the salinity of the seawater left behind, and thus an increase in the density of the water mass. In the Norwegian Sea evaporative cooling is predominant, and the sinking water mass, the North Atlantic Deep Water (NADW), fills the basin and spills southwards through crevasses in the submarine sills that connect Greenland, Iceland and Great Britain. It then flows very slowly into the deep abyssal plains of the Atlantic, always in a southerly direction. Flow from the Arctic Ocean Basin into the Pacific, however, is blocked by the narrow shallows of the Bering Strait."

They have had to leave out the cause of seiches and of course the original cause of the mechanics as the ultimate force of the solar system is far from clear.

What is clear however is that they do not mention the input that seiches caused by earthquakes MUST have on rotation. There is no way for acoustic waves to move across the planet in a straight line the effort then must cause rotation. And that is all there is to be said on the subject.

(...but that is not going to stop me saying it.)

What happened after that large quake is that they all restarted happening again in th usual places. or some reason the islands around Fiji have a place at the core of the causes.

I suspec that with this restart we can watch the development of the weddell Sea earthquakes procuring heat for the upwellings nearer the equator with the result being a more dependable tropical storm regimen.

What happened after that large quake is that they all restarted happening again in th usual places. or some reason the islands around Fiji have a place at the core of the causes.

I suspec that with this restart we can watch the development of the weddell Sea earthquakes procuring heat for the upwellings nearer the equator with the result being a more dependable tropical storm regimen.


An earthquake in the southern oceans like this one in Atarctica:
2017-02-23 at 20:13. 5.0 M. North of Severnaya Zemlya 86.167°N 74.413°E

....can have an effect far greater than suspected from a relatively minor affair. This is because current flow is so readily confined to the surface when powered by winds and temperature difference.

Seiches set off by small quakes accomplish so much more that it is not easy to guess at their effects.

The outflow from the superchilled waters of the Weddell Sea does in fact halt to a certain extent the overflow of the global conveyor. Or at least it diverts the currents.

Default Fluid Flowers

The daffodils are in bud it must be the march of the season. So how do data bases react to changes in subspecies?

Or is it a just a least squares poll count?
It can't be any more difficult to account for daffodility any more than it must be to count the things in the first place, can it?
