transport layer processes occur between the applicaitoin layer and internet layer of the TCP/IP and between the session layer and network layer of the OSI model.
the physical layer (layer 1) manages hardware connections, handles sending and receiving binary signals, and handles encoding of bits.

A tornado would occur in the troposphere, the layer closest to the Earth.
I believe that the layer in which sun spots occur would be the chromosphere. The chromosphere is the second layer in the sun's atmosphere and is about 2,000km above the photosphere(the first layer).

The Mesosphere
They occur on the photosphere of the Sun.
It first occurs at the application layer.
