In the upper mesosphere and the lower thermosphere, gas particles become electrically charged. Because these charged particles are called ions, this part of the thermosphere is called the ionosphere. In polar regions these ions radiate energy as shimmering lights called auroras, usually in latitudes above 50 degrees.
The Aurora Borealis and its southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermosphere, the outermost actual atmosphere. Above this layer, the exosphere has so few molecules that they can escape into space.

The Mesosphere
They occur the northern atmospheres. Closer to the magnetic poles where the solar storms hit the earth the hardest.
They occur in the Mesosphere.
the chromosphere
The Auroras is collision that occurs during the Northern lights when active sun particles hit the earth's atmosphere. Auroras can be seen every year in the north and south pole hemisphere in an array of colors including pink, light green, yellow and blue.
The troposphere
The Mesosphere
Ionosphere of Near northern hemisphere polar regions
They occur the northern atmospheres. Closer to the magnetic poles where the solar storms hit the earth the hardest.
Auroras occur in the mesospere.
I do not know for sure but I think that auroras would occur.
troposphere
Hurricanes, tornadoes, and virtually all other forms of weather occur in the lowest layer of the atmosphere, the troposphere.
A tornado would occur in the troposphere, the layer closest to the Earth.
They occur on the photosphere of the Sun.
They occur in the Mesosphere.
No, it has no atmosphere.
