What natural phenomena are the weather phenomena we observe?

All kinds of weather phenomena we observe are natural phenomena in the atmosphere.

Weather phenomenon refers to some physical phenomena that occur in the atmosphere and on the ground, including precipitation, ground condensation, sight distance obstacle, lightning and other phenomena, all of which are produced under certain weather conditions. In ground meteorological observation, all kinds of weather phenomena are represented by unified special symbols.

The role of the atmosphere

The atmosphere is the outermost gas layer in the outer circle of the earth, which exists in the whole outer layer of the earth. The atmosphere is the transition layer from the earth's land and sea surface to interstellar space. There is no obvious upper limit, and it can last for more than 800 kilometers. However, the farther out into the atmosphere, the less. There are still thin gases and elementary particles at the altitude of 2000 ~ 16000 km. It surrounds the sea and the land. There is also a small amount of air in underground soil and some rocks, which can also be considered as a part of the atmosphere.

The atmosphere plays a great role in the formation, development and protection of living things. Because of the existence of the atmosphere, most meteorites flying to the earth are blocked, and most ultraviolet rays in solar radiation and high-energy particle streams from the universe are intercepted, thus protecting the life of the earth from external attacks. Therefore, the atmosphere is the barrier of the earth's surface and life.
