Extraordinary barometers

Mcooker: best recipes About animals

Extraordinary barometersIt is well known that weather changes occur in a certain sequence. For example, bad weather is usually preceded by changes in pressure, sky conditions, illumination. A number of living organisms, possessing organs sensitive to meteorological changes, by their behavior can signal a change in weather.

What is the reaction of plants to weather changes? It turns out that it is synchronous with these changes, but not ahead of them. Although in some cases, plants, responding to subtle fluctuations with which the weather begins to change, give us a signal, draw our attention to what is happening in nature. The rest of nature also responds in its own way to weather changes.

For example, villagers know that before a severe storm, which is usually associated with the approach of a cyclone, and, therefore, with a significant drop in pressure, the water level in reservoirs (wells, ponds, springs) rises; bubbles appear in ditches, in swamps, "gurgling" is heard; the smell begins to be felt more sharply where stale leaves, grass or algae rot. The decrease in pressure promotes the spread of odors, which usually stick to the surface.

Extraordinary barometersThere is a widespread belief among sailors about the ability of seagulls to predict the weather: if seagulls land on the water, the weather will be good, and if they wander along the shore, it will deteriorate. It is believed that if birds fly over water, it will be windy, etc. The behavior of gulls reflects their ability to quickly adapt to the prevailing at the moment. weather... When it's sunny, the wind is usually weak. Water is cooler than air, and there are no upward currents above it. Seagulls can fly only by working their wings intensively. Tired, they willingly sit on the water. And when a storm approaches, the fish go to the depths and the seagulls are forced to look for food on the shore.

There is also such a sign among the people:

If the crows land at random, the day will be calm, if everything heads in one direction - with a strong wind.

This observation is only partially true. Indeed, in windy weather, crows, like other birds, taking care of maintaining heat and stability, sit down so that the air flow blows over the plumage, without penetrating under it, the body of the bird, streamlined by the flow, renders the least resistance to the wind. This is achieved if the bird sits against the wind with its beak. In calm weather, the direction in which the bird's head is facing does not matter. The birds' sensitive reaction to the already existing weather is taken for the ability to predict.

There are many such delusions. Even in popular science literature there are statements that "there are about six hundred species of animals" that predict the weather. It seems that if this figure is reduced even tenfold, then in this case the truth will still be far away. It would be more correct to say that more than six hundred species of animals react in one way or another to changes in the weather. The behavior of several dozen of them makes it possible to judge the weather in the coming hours. The ability of animals to "foresee" the weather many days in advance or even a whole season has not been confirmed by scientific research.

Extraordinary barometersIt is widely believed that some animals "have a presentiment" whether the winter will be long and cold or not. And depending on this, they say, they make supplies for the winter (squirrels) or equip, insulate their homes (muskrats, beavers). At the same time, it has been scientifically proven not so much by meteorologists as by zoologists that such statements are erroneous. The behavior of squirrels, muskrats, beavers, as well as bears, ferrets and other animals, is determined by the state of the weather today, not in the future. And only to the extent that late autumn weather determines the character of the coming winter, the behavior of animals can suggest the character of the coming season.

There are plenty of examples of the inability of animals to "foresee" the weather and associated living conditions. The situation created in the winter of 1975 is still fresh in my memory. In Belarus, Polesye lakes spilled over many hundreds of meters, flooded animal dwellings. Then people had to help out beavers in trouble.

This is how the valley stands with living "barometers" in the nature that surrounds us.
