Zeno-25 posted:190 mph gusts in that 12z euro run Not good at all. Whatever anyone thinks about this area of the country, there is literally no land mass to weaken the surge or the winds. From south-Central Mississippi to Corpus Christ, the coastline is basically just all swampland. These areas flood on a dime in rainstorms that last barely 20 minutes. Gonna' be super-hosed. Not to mention the I-10 corridor there is gonna' be affected.

PostNouveau posted:Looking like it might be a "why not both?" situation. I know that region pretty well having been in the oil & gas industry previously for years. There's not much that's situated right on the Gulf; the larger concern if there are breaches at refineries/pipelines during the storm are the inland waterways & intercoastal canals. There's also the possibility of acute spillover into adjacent areas that are residential.

I'm sure they've spent the time since reinforcing it, so shouldn't be an issue!

Its probably going to result in a major ecological/health disaster as all those refining and chemical plants are basically giant warehouses for extremely toxic poo poo and gently caress up the local population even in the best of times

PostNouveau posted:Yeah something called "wind sheer" killed it. I understood it for exactly 5 minutes after the youtube man explained it but now that's completely gone. Wind shear. It's when there's a big difference in wind speed at different elevations. Basically, strong winds high up and light winds on the ground destroys the spiral structure of a hurricane. Can promote instability in other contexts but hurricanes need different conditions to stay intact.

Is category determined by pressure at all? I thought it was just wind speed? What's the dummy explanation for why lower pressure is worse?

actionjackson posted:Is category determined by pressure at all? I thought it was just wind speed? lower pressure = higher differential = faster flow from high to low https://sciencing.com/barometric-pressure-vs-wind-speed-hurricane-19558.html quote:When a tropical cyclone reaches hurricane strength, its low-pressure center is called the “eye” of the storm. Acting like fuel that feeds more energy into the storm, moisture from the warm water is converted to heat in the bands of rain that spiral around the eye. As air is pulled into the eye, it rises rapidly and then condenses, cooling and releasing large amounts of heat into the atmosphere before the air descends and begins the cycle again. This refuels the hurricane, lowering the barometric pressure on the ocean surface, which pulls more air in and upward, strengthening the hurricane. The lower the barometric pressure at the center of the storm, the stronger the hurricane, and vice versa.

actionjackson posted:Is category determined by pressure at all? I thought it was just wind speed? Category is wind speed. Pressure is related to windspeed but is not 1:1. Think of it like an ice skater spinning: If they stick their arms out they start spinning slower. A larger, broader system will have lower wind speed at the same pressure compared to a smaller, compact one.

The smoke from the Australian bushfires earlier this year made it all the way across the Pacific to South America. In fact I think particles of it eventually went all the way around the globe and ended back up in Aus. https://www.sbs.com.au/news/bushfire-smoke-will-circle-around-the-globe-and-return-to-australia-nasa-says Also Australia's fire season has begun up in the Top End (the north of the country) with a strong start. https://twitter.com/abcnews/status/1298371444234051586 Helith has issued a correction as of 01:10 on Aug 26, 2020 |

actionjackson posted:is it black static because they ran out of colors? Kinda yeah. That's an IR band, and the color scale corresponds to the temperature of the cloud tops. Black just means that the cloud tops are cold enough (aka high enough, aka the tops of thunderstorms) that they've essentially saturated the color scale. It's not at all unusual, but it does look cool. In this case, it's the shortwave IR band. The temperature change that sweeps across the field of view is sunset; the sensor is no longer detecting reflected sunlight, so everything suddenly looks much colder (and more accurate to its actual temperature). The longwave IR bands don't have this problem because the reflected sunlight is generally negligible in comparison to the signal from the Earth. If you want to play with GOES data yourself, have at it here.
