Weather

The answer to this question is not so easy. Everyone knows what it is, but not everyone can explain. To do this, you need to figure out what the weather is composed of.

First, it is air temperature... Everyone can say according to their feelings that it is cold, warm or hot today. For accurate temperature measurement, a device is used - thermometer.

Secondly, it is cloudy... If only individual clouds are visible in the sky and the sun is shining, they say that it is clear today. If there are many clouds and they often cover the sun, they say, partly cloudy. If the whole sky is covered with clouds and the sun is not visible, they say that it is cloudy today.

Third, it is precipitation... These include rain, snow, hail.

Fourthly, it is wind... He can be weak or strong. A very strong wind is called a hurricane. The direction of the wind is also different. It is determined on the side from which the wind is blowing. For example, the north wind blows from the north, the south wind from the south.

The combination of air temperature, cloudiness, precipitation, wind - this is weather.

Of course, we have named only the main terms of the weather. You can add such natural phenomena as thunderstorm, fog, rainbow to them ..

• Look at the drawings and photographs. Tell us what you know about these weather phenomena.

How is the weather predicted?

In many places on earth there are meteorological stations (weather stations) where scientists observe the weather. The name "meteorological station" comes from the word "meteorology" - the science of weather.

For observing the weather, balloons are used - probes. Marine vessels are equipped with special equipment. Meteorological aircraft are also used. And meteorological satellites work in space.

Scientists process all collected information using computers and compose weather forecasts... Forecasts are scientific predictions. They are made up for tomorrow, a few days or weeks in advance.

• Consider the pictures. These devices are used at weather stations. Try to explain what they serve and how they work. Check yourself on the Clever Owlet Pages. (7)

Let's think about it!

1. What are weather forecasts for?
2. What folk signs that help predict the weather do you know?

5. What is the wind like?
6. How is the weather predicted?

Let's make a conclusion

Weather is a combination of air temperature, cloudiness, precipitation, wind. Scientists are constantly observing the weather and making weather forecasts.
