Answer 2

$\huge \color {lime} \rm{ ANSWER : }$

→While “4 O’clock Rainfall” has no technical denotation in meteorology, the term may be associated with a diurnal occurrence of rainfall under specific meteorological conditions primarily occurring during the summer in favorable geographic areas. Given vertical temperature and wind patterns conducive to convection processes, clouds form in the morning and vertically develop during the day into rain showers, or thunderstorms, by late afternoon (roughly coincident with peak daytime temperatures). “4 o’clock rainfall” then seems to refer, in the vernacular, to this regularity in the time that rain occurs in certain regions of the United States.
