The lower atmosphere is heated by the ground, which is heated by sunlight.
ultraviolet (UV)
The sun heats the atmosphere. Solar radiation largely passes through the atmosphere and warms the surface of the earth. The earth then radiates heat up into the lower levels of the atmosphere where greenhouse gases warm. The warmed greenhouse gases then continue to radiate heat in all directions warming the atmosphere and again the earth's surface.
The absorption of thermal energy from the ground heats the lower atmosphere and keeps Earth's surface much warmer than it would if there were no atmosphere. :)

The atmosphere is affected by convention because convection heats the lower atmosphere. Radiation transfers energy which other gases heat up. Conduction does not impact the atmosphere in these same ways.
By here I presume you mean earth, the sun heats the atmosphere directly, but also heats objects which in turn also give off heat to the atmosphere

The Sun
The energy that powers tornadoes ultimately comes from the sun. The sun heats the earth's surface which in turn heats the lower atmosphere. This heat can lead to thunderstorms, which, under the right conditions, can produce tornadoes.
The sun heats the surface of the Earth throughout the day, which in turn heats the lowest part of the atmosphere. The surface starts too cool down around sunset. As a result the lower atmosphere is generally warmest and thus the most unstable in the late afternoon. An unstable atmosphere is necessary for the formation of the strong thunderstorms that produce tornadoes.
