Yes, the Neo-classical characteristics that stand out most are things such as the clear profile of the people within the painting. It is easy to see the expressions on the faces yet you cannot feel the emotions within the personalities of the people depicted. The painting is of a storm, however, it portrays a time occurring just moments before the actual dramatic event of the storm taking place. Neoclassicism demonstrates the belief that a "rational state of mind is believed to be the ideal state, emotion is suppressed to the minimum."
It is called a tropical storm.
