Final answer:
A lonesomeness refers to the rotating area within a super cell thunderstorm and is associated with the potential for severe weather and tornado development.
Step-by-step explanation:
The term lonesomeness refers to (d) the rotating region of a super cell thunderstorm. Tornadoes often form from these cyclones, which are areas of rotation typically about 2-6 miles in diameter within the thunderstorm.
When strong cold winds in the upper levels of the atmosphere interact with warmer surface winds, it can lead to the vertical development of these rotating columns of air.
Days that produce cyclones are often associated with severe weather warnings and have the potential to develop into tornado activity, although not all cyclones result in tornado formation.
