Fronts

The uninitiated use the term weather front, ona apage dedicated to weather this is a waste of the word weather. It is just that some people don’t like you to let them know you are taking about weather as oppsed to events from the second world war, the first one to have a greater affect on the front line than on lofistics. Maily because everything in WW2 became the front line with the development of submarines and long range aircraft.

Also on the page is: Trough https://www.metoffice.gov.uk/weather/guides/what-does-this-forecast-mean

An elongated area of relatively low surface pressure. The troughs marked on weather charts may also show an area of low thickness (thickness trough). It can also mean a disturbance in the upper troposphere (upper trough). All are linked to increasing cloud and risk of precipitation.

These are usually represented as smallish arcs if I understand the guide correctly.

Earlier in the month they were all over the Sabancaya eruption on the North Atlantic chart. This occured when the east coast of the USA was struck with mountain climbing hurricanes -fake weather.

They can be identified by their cold fronts and too, I think, by their warm fronts but the most consternation that I got from them was these curved black lines. Troughs it seems, are satans horns and hooves.

These remind me of the recent episode that devastated the USA eastern seaboard earlier.The troughs are no so numerous as with that devastating weather but It is early yet and I am still wondering where the closure went for the last spell.

It is spectacular but only Sangay has the emissions to make a mark on the charts: Sangay (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 21000 ft (6400 m)

Reventador (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 14000 ft (4300 m.) So what is going on?

Something is not being reported.

I imagine these are being blown out to sea. We will have to follow them and see.
