Michael officially stronger than Katrina at landfall

Hurricane Michael is a record of the storm and important metrics are more powerful when landing than infamous past monsters like Katrina and Andrew.

According to Meteorologist Phil Klotzbach of Colorado State University, Michael is the third hurricane ever to land in the United States based on a pressure of 919 mbar.

"Miva" is a meteorologist's way to determine barometric pressure. Lower mbar, stronger storm

Michael was only behind the "Labor Day" hurricane (892 mbar) in 1935, Hurricane hit Florida Keys and Hurricane Camille (900 mbar) and attacked the Gulf severely in the summer of 1969.

Derek Herndon, an atmospheric scientist at the Meteorological Satellite Research Institute, told National Geographic, not wind speed, that the best way to measure hurricane strength should be considered atmospheric pressure.

In a study conducted last year at Nature Communications, it says, "It can explain historical economic loss better, not maximum wind speed." It also refers to the destruction of hurricanes. According to research, this is because the central pressure combines the wind speed and the size of the storm.

At landing, Hurricane Katrina measured 920 mbar. However, Katrina eventually drowned a large city like New Orleans and killed more than 1,000 people, so it is considered a more destructive and destructive storm than Michael.

Sustained wind speed at landing - According to Mexico, 155 miles per hour near Mexico beach - Michael fell to fourth place after falling after these two hurricanes and 1992 hurricane Andrew.

The 1935 hurricane attacked at 184 miles per hour, Camille's wind was 173 miles per hour, Andrew trembled at the wind speed of 166 miles in southern Florida.

The well-known 47-year-old Saffir-Simpson hurricane strength rating - its familiar category from 1 to 5 - measures wind speed only. These three hurricanes (working day 1935, Camille and Andrew) are still the only hurricanes to attack the United States.

Category 5 hurricane wind speed is at least 157 miles per hour. Michael missed the notorious level of just two miles per hour

However, both wind speed and atmospheric pressure may not be affected by both hurricanes.

For example, Michael's Category 4 rating accurately communicates the destructive power, but the Florida state Hurricane Florida Class 1 landing last month was an example of the size limit. The scale does not take into account heavy rain - and the resulting inland flood

Whether it is a storm from the sea or a flood caused by a heavy rain, water tends to be more fatal and destructive than a hurricane.

According to NHC data, Katrina landed at a pressure measurement of 920 mbar in 2005 (about 8% lower than the pressure of 1,000 square meters above sea level). The final record in Michael before landing was a lower record, 919 mb. In history history two hurricanes landed at low pressure on the continent: Camille divided the Mississippi coast into 900 nautical miles in 1969 and the labor day storm that peaked at 892 million in 1935 He hit South Florida.

August 23, 2005; Hurricane Katrina formed in the Bahamas and landed in Florida. On the 29th, it attacked and destroyed New Orleans by the third landing, becoming the most deadly hurricane in the 2005 season, becoming one of the five worst hurricanes in American history. Look at the hurricanes that caused Katrina, precautionary measures, racial discrimination, class disparities, and the age of the government. All these can be avoided. As a newspaper article "Katrina autopsy: not just one but four storms", we have to ask ourselves whether "natural" disasters are truly natural or a product of people.

A slightly lower pressure than Hurricane Michael 's Hurricane Katrina does not necessarily mean that it is more dangerous or endangered than a storm that flooded New Orleans. According to various news reports, Hurricane Katrina did not show up in the record record, but caused more than 1,000 deaths due to infrastructure failures and lack of management of emergency resources. However, stronger hurricanes may cause such failure. In 2017, Hurricane Maria killed nearly 3,000 Americans in Puerto Rico due to infrastructure breakdown after landing pressure of 9.14 million barrels. (Maria's Puerto Rico landing is not included in the pressure record in the US Mainland because the island and the US territory Puerto Rico do not belong to the mainland USA.
