Weather phenomena don't necessarily happen in the atmosphere, do they?

No, weather phenomena must occur in the atmosphere.

All weather phenomena occur in the troposphere. The closer the troposphere is to the ground, the higher the temperature, and the farther it is from the ground, the lower the temperature. The air near the ground rises and cools gradually, forming convection. Convection is an important condition for precipitation. The thickness of the lowest layer of the atmosphere varies with seasons and latitudes. With the increase of altitude, the average temperature drop rate is 6.5 degrees Celsius per kilometer, with convection and turbulence.

Weather phenomena and weather processes mainly occur in this layer. It is located in the lowest layer of the atmosphere, extending from the earth's surface to the top of the troposphere and the starting point of the stratosphere.

Common weather phenomena:

1, precipitation phenomenon:

According to the form of precipitation, it can be divided into 1 1, in which liquid precipitation includes rain, Mao Mao rain and showers, solid precipitation includes snow, ice particles, rice snow, sudden snow, graupel and hail, and mixed precipitation includes sleet and sudden sleet. In addition, according to the nature of precipitation, there are three types: formative precipitation, continuous precipitation and intermittent precipitation.

2. Dew and icing on the ground:

Include dew, frost, fog and rain.

3. Sight distance obstacle phenomenon:

Including fog (fog, fog, fog); Light fog; Blow snow; Blizzard; Smoke screen; Haze; Sandstorm (sandstorm, strong sandstorm, super sandstorm); Blowing sand; Floating dust.

4, lightning phenomenon:

Thunderstorm, lightning, aurora.
