Weather refers to the combination of ever-changing meteorological elements and atmospheric phenomena observed at a particular location. If the term "climate" refers to the average state of the atmosphere over a period, then "weather" is the current state of affairs.
Weather plays an important role in human life, even affecting history. It is enough just to remember the migration of peoples, strong winds were crushing mighty armada. People try to study nature as much as possible in order to be able to predict weather changes. Predictions about whether tomorrow will be warm or cold, whether it will rain or shine the sun, are thousands of years old.
But on a scientific basis, they began to be made only from the nineteenth century. In addition, there are many famous folk signs about the weather, some of which are still nothing more than a myth.
If there are few stars in the sky, it will soon rain. According to this belief, the many stars in the night sky indicate that the coming day will certainly be sunny. And a small number of them indicates the coming rain. In fact, this is not entirely true. The fact is that the absence of stars in the sky only indicates that there are clouds in the sky. Yes, this to some extent may mean future precipitation, but such a phenomenon cannot be considered an unambiguous criterion. After all, the clouds move quite quickly, by the morning they may simply not remain.
If the leaves show their lower part, then it will rain soon. Forecasters believe that this sign is usually correct, although in this case we are not talking about all trees. Poplar has long been considered a reliable predictor. Any increase in air humidity leads to softening of the leaf body and its subsequent eversion.
The approach of storms and cataclysms is the first to be felt by animals, especially dogs. The fact is that some animals are more sensitive to pressure drops in the air. The dog's sensitive hearing allows it to hear the distant roll of thunder before its master. Scientists believe that indeed the sensitivity of animals allows them to respond to the coming earthquake and tsunami a few seconds earlier than humans. But the statement that dogs begin to eat grass before the storm is false. This behavior can only indicate that the dog is sick, or simply a coincidence.
If seabirds start walking on the sand, then the weather will soon turn bad. It is true that seabirds, sensing the approach of rain, consider it best for themselves to stay close to land. After all, they are well aware of pressure drops in the air. But it is not worth focusing entirely on their behavior. If you notice a group of birds gathering on the beach, then the rain has most likely begun.
Pain in the legs, arms, back testifies to the coming changes in the weather. Some people believe they can predict precipitation based on their own painful sensations in some parts of the body. This may indeed be due to the fact that the drop in atmospheric pressure results in a slight dilation of the blood vessels. So the approaching rain or storm has such an effect on the joints, spines, muscles and sinuses. But this is just a theory, which some doctors are very skeptical about.
To find out the air temperature, you need to listen to a cricket. There is an example that you can find out the air temperature in degrees Fahrenheit by counting the number of clicks of this insect in 14 seconds. Then add 14 more to the result obtained. Although the exact formulas are constantly changing, this one remains the most popular. The most amazing thing is that this approach actually works. After all, the metabolism of crickets is largely tied to weather conditions.
When a spider weaves its webs in the morning, it indicates good weather during the day. If the insect destroys its creation, then it will soon rain. According to this belief, spiders anticipate the appearance of rain, escaping from the prepared nets. But such a statement is rather dubious. The point is that the spider has enough other warnings to change its behavior when predicting future weather.
