Solar radiation, also known in the vernacular as sunlight, is the total luminance and consequent atmospheric movement created by the sun's energy. Since the sun's solar footprint changes seasonally, the jet stream also moves in concert with this movement.
In the case of atmospheric heating, temperatures will be either greater or lesser, depending on seasonal local/regional levels of cloud coverage. This resulting convective heating/cooling sequence can, and typically does, redirect the jet stream.
Again, the effect on jet streams is largely dependent on solar radiation, convective cooling/heating and seasonal evolutions. In this case, therefore, if Earth is in a night phase, jet stream movement will typically respond to cold air masses, just as a day phase tends to respond to higher temperatures.
The geo-location of upper-level jet streams are redirected during various climatic periods known as the El Niño-Southern Oscillation. This condition describes increased precipitation along the Gulf Coast and Southeast, with various jet streams responding to this movement accordingly.
Similarly, the redirection of jet streams can also be seen during climatic periods referred to as La Niña events. In this condition, precipitation is diverted into the Pacific Northwest due to a more northerly storm track, and the resulting jet streams follow and support this evolution.
