The weather

 The weather occurs in the atmosphere, or in the air between the Earth’s surface and space, which consists of a few layers. 

The weather is that it is the state of atmosphere at a definite time and place on the Earth. 

It can be hot or cold, dry or not, calm or stormy, clear or cloudy. 

This condition is influenced by air pressure, temperature, humidity, precipitation.

 Temperature is how hot or cold something is, for example air, land or water. 

 The air around us is never completely dry – it is humid. 

Humidity is the amount (количество) of water vapour in the air. 

 Precipitation is the term given to moisture that falls from the air to the ground. For example: rain, snow, hail, sleet, drizzle, fog, mist.

Atmospheric pressure is the weight of the air pressing down on the Earth’s surface. 

Warm air is lighter than cold air, cold air is heavier than warm air.
