How do meteorologists predict the weather?

The term "weather" includes all states of the atmosphere. "Weather" includes atmospheric conditions such as cold, warm, dry, humid, sunny, cloudy, windy, still. The weather changes every day, and everything that happens during the year is called "climate".

Weather is influenced by various factors, but the most basic is the Sun. The heat from the sun evaporates water and warms the air, which causes rising currents of warm air to lift water vapor into the sky. There, the air cools and the vapors condense into rain. This can happen gradually or quickly. When the weather changes abruptly, there are storms.

There are about 200 weather stations in England, about the same number in the rest of Europe. In addition, "weather ships" located in the Atlantic, as well as special aircraft on duty, monitor weather changes. The weather forecast is based on these messages and other meteorological data.

The maps that weather experts study can tell them a variety of information: areas with the same pressure, areas with the same temperature, wind direction, cloudiness or clear skies, rain or snow, the amount of rain that has fallen, areas with high or low pressure.

Meteorologists, by studying a map, can predict what to expect under given atmospheric conditions. They know that low pressure means strong winds due to the movement of cold air to replace warm, rising, moisture-laden air. High pressure means good weather.

In the Northern Hemisphere, winds in high pressure areas blow clockwise. At low pressure - counterclockwise. That is, even the direction of the wind can be predicted. Meteorologists also know the speed of movement of areas with different pressures.

Knowing all these details, as well as having weather reports from many parts of the country, the meteorologist has a good idea of what the weather is expected in your area!

Which countries require participation in elections?

In more than twenty countries around the world, the law provides for mandatory participation in elections for all those eligible to vote. While some of these countries do not provide penalties for non-compliance with this law, others, such as Australia, will have to pay a penalty for failure to vote. In Peru and Greece, irresponsible citizens may be denied public services by various agencies. And if a Brazilian over the age of 18 misses the election without a good reason, he will not be issued a passport until he votes in the next one.

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 ... >>

cocaine vaccine 10.07.2002

The English biotechnology company Zinova announces the development of a vaccine that eliminates the adherence of a drug addict to cocaine.

The vaccine works by preventing the drug from reaching the brain. Cocaine molecules are small enough to pass through the blood-brain barrier that protects the brain from toxic substances. The vaccine stimulates the production of antibodies to cocaine, which adhere to the drug molecules, making them larger, after which they get stuck in the barrier. Cocaine ceases to enter the brain, the addict loses his usual pleasure and quits the drug that has become useless.

Clinical trials of the vaccine have begun. Meanwhile, the company is preparing a similar vaccine against nicotine.
