What's the difference between a hurricane and a typhoon?
1. Difference of activity range: Typhoons mainly refer to tropical cyclones generated and active in the northwest Pacific and the South China Sea, while hurricanes refer to tropical cyclones generated and active in the Middle East Pacific and the North Atlantic.
2. Difference of wind grades: From the grading point of view, typhoons with winds above 12 are divided into three grades, while hurricanes have more grades and higher upper limits. A first-class hurricane is equivalent to a typhoon or a strong typhoon, a second-class hurricane is equivalent to a strong typhoon, and a third-class hurricane is equivalent to a strong typhoon or a super typhoon.
3. Naming difference: From the naming way, the names of hurricanes are all taken from people's names, which is relatively simple. Typhoons have various names and are provided by 14 member countries (regions) affected by typhoons in the Asia-Pacific region.
How to resist hurricanes?
First of all, about three days before the hurricane, the meteorological department will generally issue a hurricane warning. When you receive the warning signal, you must not turn a deaf ear. We should know that the preparation time these days is the basis for our safety, and many preparations must be carried out and completed in these days.
When receiving early warning information, we should reserve water, food, medicine and daily necessities in time. Any natural disaster will affect people's going out and living, and hurricanes are no exception. Therefore, we should prepare food for at least three to seven days, as well as trauma medicine, candles, flashlights, whistles and other items, which can help us seek vitality and spend the hurricane period smoothly and safely.
Secondly, we should strengthen doors and windows, especially villas by the sea or bungalows in rural areas. By fixing and pasting the roof and windows of the house, the hurricane can be effectively prevented. Only when the house is saved can we be safe.
If a hurricane comes, it is necessary to unplug the power switch and various electrical appliances at home in time to avoid the indoor power supply from catching fire due to the breakage of outdoor wires.
If a hurricane comes, we will be outdoors. Don't stand on telephone poles, trees or high places. These places are extremely dangerous. If conditions permit, we should choose to hide in the lower part of the nest wind, so as to ensure our safety to the maximum extent.
Finally, in order to nip in the bud, before the hurricane comes, we should make copies of important documents such as insurance and licenses at home to avoid losing proof of property compensation due to floods and fires caused by the hurricane.
What does a hurricane mean?
Hurricanes in the Atlantic Ocean and the East Pacific Ocean, strong and deep tropical cyclones (maximum wind speed 32.7m/s, wind 12 or more) are called hurricanes, and also refer to strong winds and any tropical cyclones and any strong winds with wind 12. There is an eye in the center of the hurricane. The smaller the eyes, the greater the destructive power [1]? Its significance is similar to that of a typhoon, but it is produced in different places.
Super hurricane Ida landed in the United States.
According to the latest news, Hurricane Ida landed on the coast of Louisiana around 1 on the morning of 30th Beijing time. When landing, the intensity was a category 4 hurricane (16- 17, equivalent to the super typhoon level in China). The measured air pressure in the center of the aircraft is about 930 hectopascals, and the maximum wind speed is 240 kilometers per hour.
Although the wind level exceeded the "Katrina" of 16 years ago, it is difficult to cause similar destructive power combined with wind direction and various meteorological data.
Influenced by IDA, the Mississippi River, the largest river in the United States, even flows in the opposite direction (from south to north), and the water is slapped ashore, and some islands in the estuary are erased from the map.
Experts say it is not uncommon to encounter more extreme weather conditions due to global warming.
In addition, in response to Hurricane Ida, more than 90% of oil production and nearly 85% of natural gas production in the Gulf region have been "closed", which means that oil and gas prices will continue to rise in the future.
In fact, as of the close of the 27th, the futures price of light crude oil for June delivery in the New York Mercantile Exchange rose by $20211.32 to close at $68.74 per barrel, with an increase of 1.96%, which has increased by10.62 in the past week. London Brent crude oil futures for delivery on 202 1 and 10 rose by 1.63 USD to close at $72.7 per barrel, with an increase of 2.29%, up by 1 1.54% in the past week.
It is reported that Hurricane Katrina 16 years ago caused the dam in New Orleans to burst, causing more than 1800 deaths and economic losses of nearly $200 billion.
