Typhoons in Korea amplified wildfires in America. Here's how.

The year 2020 played host to an uncharacteristically large number of natural disasters. The year began with large wildfires in the Amazon rainforest and Australia. A series of wildfires broke out in the American states of California during summer and Oregon in September 2020. In particular, the Oregon wildfire intensified to an uncontrollable extent and was spread over a wide area by strong gusts of wind that carried it forward. These unseasonably strong winds may have been stoked by an unexpected source: typhoons on the other side of the Pacific Ocean.

In late August and early September, three storms—Bavi, Mayask, and Haishen—occurred just two weeks apart in the Korean peninsula, causing floods, mudslides, and several casualties. In a recently published article in Geophysical Research Letters, evidence was presented that these storms had more than enough energy to perturb the jet stream—creating an atmospheric “wave train” that amplified weather conditions, which increased the likelihood of wildfires in North America. This evidence was discovered by an international team led by Associate Professor Jin-Ho Yoon from Gwangju Institute of Science and Technology, Korea, and Prof. Shih-Yu (Simon) Wang from Utah State University.

Commenting on their findings, Dr. Yoon states, “Typhoon Haishen prolonged the initial fire spread and maintained anomalously hot and dry conditions in California and extreme wind events in Oregon.” “One typhoon of this magnitude would not be unusual in Korea each year,” said co-author Prof. Wang, “But three in two weeks? That was quite historic.”

How could a typhoon that hit Korea affect weather in America? Dr. Yoon explains that the outflow from the three typhoons amplified an atmospheric “wave train,” creating a reverse air flow across the Pacific by shifting a climatologically west wind regime to an east wind regime. It also increased the pressure gradient across Western America, such that the atmospheric pressure was at an all-time low in the last 40 years.

The team’s findings show how weather-related disasters, often [ … ]

Perhaps there is climate change, but I’m skeptical that it totally caused by human activity. For millions of years there have been cyclical warmings and coolings on our planet, way before people were around.

It must be Trump’s fault.

I don’t think there is any doubt that climate change is shaking things up and causing weird weather patterns.

It’s called the butterfly effect and here’s a perfect example of it:

US railroads are exactly 4 feet 8.5 inches wide. Why did they pick such an odd number for that? Well, the same people who built the first railways in America happened to be wagon makers, and their tools where all designed to make wagons that where 4 feet 8.5 inches wide. Why that size for wagons? Because that is the size they made them in England. So why did they make it that size in England? It’s because all of the roads already had ruts in them that where this size, and if you made wagons smaller the wheels would snap trying to fit into the ruts, so they made the wagons the right size to fit. So why where the ruts that size? Well, 2,000 years ago when the Romans conquered most of Europe, their war wagons where the ones that made the first roads and so every wagon after that had to be made to the same size as those ancient roman war chariots.

So, why where the chariots that size? Turns out 4 foot 8.5 inches is the minimum size needed to fit the butt end of 2 Roman war horses in the front of their chariots.

Now, remember the US space shuttle? Remember those tall white rockets on either side of the main orange tank? Those are solid rocket boosters, and they are made in America but have to be shipped to Cape Canaveral via railway. The engineers who designed the space shuttle had wanted those boosters to be fatter, but the railway went through several tunnels which where just wide enough to accommodate a rail car with a width of 4 feet 8.5 inches.

This means that a critical design feature of one of the most complicated machines ever built by mankind was decided over 2,000 years ago based on the width of a horses ass.
