Underground train fills with water as part of China suffers 'heaviest rain in 1,000 years'

Source: Sky News

Parts of China have been hit by "the heaviest rain in 1,000 years" - with footage showing underground train carriages filling with water.

More than 20cm of rain fell on the city of Zhengzhou, Henan province, in a single hour on Tuesday. In the recent European floods, the worst-hit areas of Germany saw 18.2cm over three days.

At least 25 people died and seven went missing in the floods, local authorities said, as 100,000 were forced to flee their homes, according to China's state news agency Xinhua.
...
More than 30 reservoirs in Henan have exceeded their warning levels and overnight the rainfall caused a 20-metre breach in the Yihetan dam in the city of Luoyang west of Zhengzhou.

Systems are stalling out and training over the same spots. We had it happen here (the Monday before this past one when the German floods were occurring) in the PA county northeast to Philly, along with the adjacent NJ county on the other side of the river from there. Locations were reporting 10" of rain in a couple hours and they are gathering all the damage costs to attempt to qualify for a federal disaster declaration. A few of those same places got another whammy this past Saturday with more inches tacked on.

In those situations where the impacted areas have nearby rivers and creeks that include dams/levees, any breaches in those dams or levees (like apparently what happened in China and Germany) will literally take a bad situation, and make it absolutely catastrophic.

Meanwhile with the stalling if the flow, there were other parts of the world (including in the NW and north central U.S.) getting extreme and unrelenting heat (without any rain), and in popular meteorology parlance - "dry begets dry".

that is the prevailing theory.

The melting has impacted the PV (Polar Vortex) that spins around up at the poles and displaces lobes of it at times in what is called a "sudden stratospheric warming" event, and that in turn causes dips in the flow of the (northern) jetstream, in some cases, significantly. When that happens, it results in a ripple that causes the formation of a "ridge" over other areas, that allows warmer than normal air to flow over them, while the colder than normal air flows into the dips.

There have been a few recent periods where the arctic ice was able to regenerate but overall this year has been pretty bad.

Here's one, for 7.2 inches in 72 hours:

More than 182mm (7.2ins) fell in 72 hours in some areas between 12 and 15 July, according to Deutscher Wetterdienst - the German meteorological service.

I cannot imagine how bad that must have been considering what happened here.

Never mind, found it...

China's new coal power plant capacity in 2020 more than three times rest of world's: study

SHANGHAI (Reuters) - China put 38.4 gigawatts (GW) of new coal-fired power capacity into operation in 2020, according to new international research, more than three times the amount built elsewhere around the world and potentially undermining its short-term climate goals.

Something about 'chickens coming home to roost' comes to mind.

23. Two dams in China's Inner Mongolia collapse after torrential rain

This was before the subway flooding, different area.

SHANGHAI, July 19 (Reuters) - Two dams in China's northwestern region of Inner Mongolia have collapsed after torrential rain, the water ministry said on Monday, highlighting the safety risks posed by ageing infrastructure during the summer flood season.

The dams, in the Inner Mongolian city of Hulunbuir, collapsed on Sunday afternoon. They had formed reservoirs with a combined water storage capacity of 46 million cubic metres, the Ministry of Water Resources said.
...
Hulunbuir's city government said on its WeChat account that 16,660 people have been affected, with 326,622 mu (53,807 acres) of farmland submerged. Bridges and other transport infrastructure had also been destroyed.

Footage posted on Chinese social media showed one of the dams being completely swept away by the water, inundating nearby fields.

China would know this since they are a very long-lived culture. They have history records on this in one form or another.

If "heaviest rain in 1000 years" doesn't raise eyebrows and get certain people thinking about climate change, then I don't know what will.
