What is weather and why does it change frequently?

What we feel and how we feel the environment around us when we go outside is called the weather. We will notice that it has become warmer or colder outside, the wind has blown, the hot sun has peeped out, and it has started to snow. The totality of such circumstances is usually called the weather. Science has introduced special measurements of various weather indicators: air temperature (the Celsius or Fahrenheit scale is used for measurement), wind speed, pressure, description of the types of precipitation (hail, snow, rain, fog). The weather changes under the influence of many factors: the seasons of the year, the birth and advance of the cyclone, changes in atmospheric pressure, and even under the influence of solar energy.
