What happens at the epicenter of a hurricane?

A hurricane is a wind twisting into several spirals at a terrible speed. When the wind blows at a speed of 120 km/h, the pressure along the axis of the air column drops very quickly. This area of low pressure in the center is called the hurricane's epicenter. This is sometimes called the "eye" of a hurricane. The epicenter can be from 15 to 30 km wide. The low pressure at the epicenter causes seawater to be easily sucked into the epicenter and rise up. Very heavy showers sometimes occur in areas of low pressure.

The heaviest rain falls from the clouds around the epicenter of the hurricane. The "eye" of a hurricane can be thought of as a hole in a donut. The winds blow around the epicenter, and inside it is calm. The sky above it can be clear, free of clouds. The winds there are weak, usually less than 34 km/h.

If a hurricane overtakes you and you fall into its epicenter, at first you will feel a strong wind, then you will be wet through with rain. The epicenter of the hurricane will pass, and there will be a period of calm clear skies. Then again it will rain and strong wind, but this time blowing in the opposite direction.

Why does pressure drop rapidly along the axis of the air column, forming the epicenter of a hurricane? How is the epicenter of a hurricane formed - its "eye"? Meteorologists who study this phenomenon do not have an exact explanation for what is happening.

Random interesting fact from the Great Encyclopedia:

When were bricks first used?

If you were asked to name a durable building material made by man, then most likely you would name a brick. It seems to be true: brick is able to survive granite, limestone and even iron!

Brick is quite a modern building material. It is used all over the world. But at the same time, brick is the same age as civilization! The Babylonians and Egyptians were making and using bricks for building as early as 3000 years before our era. According to the materials of archaeological excavations, it can be concluded that the brick was known even earlier.

Making bricks in ancient times was very hard work. The material for their manufacture was clay or shale, and then they were fired at a high temperature. The clay was kneaded and mixed with water without the use of any machinery: it was stirred by workers with bare feet. Chopped straw was added to raw clay for greater strength. The mixture was then used to make bricks of various shapes by hand, after which they were laid out in the sun to dry.

This method was used for many years, until it was found that firing clay on fire increases the strength of bricks and makes them much more resistant to moisture. No more straw needed to be added. Bricks dried in the sun would have been unsuitable for England, but in the hot Middle Eastern countries such bricks turned out to be so durable that some of the bricks from the buildings of ancient Babylon have survived to this day.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Diamond cutting robot 19.01.2009

A group of engineers from the Institute for Technical and Economic Mathematics in Kaiserslautern (Germany) was able to fully automate the process of cutting precious and semi-precious stones. The machine built by them not only saves up to 30% of the weight of the stone, but also polishes ten times more accurately than the most experienced cutter.

First, the machine determines the size, shape and relief of the stone, then calculates what configuration is best for it, and presents several possible options on the monitor screen. The choice is up to the person - the operator of the machine. After 20 minutes, the stone is cut and polished. The unit has been operating since the beginning of 2008, grinding tourmaline, beryls and quartz.

Experts rate the results as remarkable. In the future, the developers intend to create a computer program that will allow you to choose between the most economical (when a minimum of material is lost) and the most beautiful cut, which creates the most spectacular play of light in the facets. But will mechanically cut stones get that individuality that only the hand of a master gives? Any stone is unique in its own way due to its shape, color, structure, the creators of the machine say.

And yet, in the passport for each piece of jewelry, they will indicate whether it is hand-cut or mechanical, so that the buyer has a choice.
