This is not always a predictable "lady." In our life we deal with her every day, sometimes we rejoice in her, often think of her with annoyance, sometimes she spoils our property and well-being. All these weather conditions, it happens, are safe or unfavorable. What is the weather like? Let's try to consider this concept in more detail.
A little about the concept of "weather"
So what is it? Simply put, this is a combination of indicators such as ambient temperature, wind, sun, cloud cover, precipitation.
Let's look at the nature of the weather conditions, where they form and what they are. What does the weather depend on? Processes in the atmosphere and air currents affect climatic conditions. Due to the fact that the air masses move, water participates in the cycle, and the sun gives its heat, we can observe a variety of weather. Meteorologists are studying these processes.
What are the elements of meteorology and what is the weather, or rather, weather phenomena such as fog, drizzle, thunderstorms, blizzards, fluctuations in air temperature, wind speed, visibility, rainbow, rainfall, snow depth, halo?
Air masses endlessly move. This affects the air temperature, which is very important for us. Its indicators vary from the highest to the lowest. The coldest on the mainland Antarctica, while in Africa, in the Libyan desert, the air temperature is always high.
Air temperature
The most pleasant temperature for a person is about 23 degrees. Although it is not necessarily comfortable for a resident of the planet with such indicators, much more depends on gusts of wind, atmospheric pressure, which sometimes causes people to feel unwell in the form of a headache. Siberia in Russia is known for having the highest pressure there, unlike any other point on the planet. And the lowest is observed in countries with a tropical climate.
Forecasting Attempts and Forecasters
Weather maps with weather forecasters make up after 3, 6 and 12 hours. They are performed both on the earth's surface and in the atmosphere, because atmospheric processes are the cause of changing conditions on the earth. The weather forecast is also reported to us thanks to satellites, which are specially released into outer space to study air flows. It also happens that forecasts turn out to be wrong, yet nature is an unpredictable thing. However, determining the weather for the short term is always the most accurate. Two weeks is the maximum period for which you can predict a decrease or increase in air temperature, rainfall and pressure. What gives the population forecasting? It is necessary for those involved in agriculture, it is extremely important for pilots and industrial enterprises.
Weather phenomena of nature. Hail
Of course, everyone is familiar with the phenomenon of hail. These are particles of ice of a rounded, not always regular shape, that have fallen from the atmosphere. What is dangerous hail? The fact is that the size of pieces of ice can be very large. Some reach 10 cm. Grad is a natural phenomenon, disastrous for the countryside. The losses from it are sometimes very large-scale. What can happen if there is a lot of hail of large size? It destroys crops, damages cars, damages buildings, causes injuries to people and animals, spoils everything on the street.
How do people try to reduce the damage that hail can cause? The hailstones begin to crush before they even touch the ground. To do this, iodide reagent is released into the air using a spray gun. Thus, the hail does not increase in size, but falls in the form of small ice floes. The most devastating natural rainfall in the form of hail fell in Kansas, Munich and Moradabad.
Thunderstorms, lightnings and their danger
Thunderstorms are inclement weather in the form of heavy rain with lightning and peals of thunder. The accumulation of electricity in the clouds leads to this natural phenomenon. Lightning flashes in the sky due to electrical discharges that occur in the clouds or below. These are quite dangerous weather conditions, which are accompanied by strong gusts of wind, constantly changing direction, raising dust into the air. Why are thunderstorms dangerous? A sharp burst of wind can tear off the roofs of houses. Great damage to the gardens is also possible, as a hurricane rips leaves from trees, breaks branches, and heavy torrents of rain can pick fruit.
Thunderstorms sometimes cost a person life, since the most dangerous direct hit of lightning. They can cause tragedy during the flight, as they knock down devices, cause breakdowns and fires. Also, the destruction of buildings and falling trees are often fatal for people.
Icy roads
Roads covered with ice are certainly a dangerous factor. After all, what is the weather? Either a blizzard, or a hurricane wind, and the next day everything turns into slippery ice. Glazed ice is a dense ice cover that not only covers roads, but also settles on wires and tree branches. Sometimes the layer can be impressive, and branches under the weight of the ice crust break off. Elegant beauty can be destructive and directly for people.
For example, injuries sustained during a fall on the ice, or even mortality, unfortunately, are often found both in villages and in cities. If the icing is announced, it is better not to take risks and postpone the car trip, as well as try not to go outside. The most dangerous are concussions due to a header, a fall on the back or in an unsuccessful position. To eliminate the likelihood of a fall, you need to pick up non-slip shoes and try to leave the house a little earlier, so as not to rush.
Severe frosts and blizzards
What is the weather, or rather crackling frost? This natural phenomenon is called cavitation. Frosts are dangerous for humans, as they can cause frostbite. Therefore, you should definitely dress in the weather and try to spend time in the cold in motion. But the greatest danger is frost (especially at night) for crops and trees. This natural phenomenon causes cracks, or freezing, that damage the bark of trees. Moreover, young and waterlogged trees are more likely to be damaged by low temperatures. To combat these weather conditions, nitrogen fertilizers are used in agricultural business.
Snowstorms can also cause significant damage - these are very dangerous weather events. Moving snow masses at high speed often causes drifts of people, buildings and cars, contributes to frostbite, destroys wires, which can cause breakdowns in power lines. Snowstorms are also the enemy of motorists.
Arid weather
Adverse weather events such as drought and dry winds occur due to a rather long lack of precipitation. In these cases, usually there is a high temperature and low humidity. Drought is dangerous because a lack of moisture is harmful to the root system of plants and crops. Most often, dry weather is inherent in the steppe, forest-steppe area and deserts. In such cases, artificial irrigation is used in agriculture.
What measures are applied to preserve crops if the weather in the area is sunny and arid? Usually this is a set of measures that are created to preserve moisture in the soil. They use special plowing across the slope, make holes to improve the soil microrelief, create intermittent furrows, and take steps to reduce the evaporation of moisture.
