Meteorologically, fall is characterized by cooling: the gradual loss of thermal energy from the land and oceans after the summer solstice. Spring, conversely, involves warming—the accumulation of solar energy as the sun’s angle increases. Fall typically brings crisp, dry air and the first frosts; spring brings thawing, increased humidity, and the last frosts. Wind patterns also differ: fall often sees strong, steady winds from the north, while spring is known for volatile, shifting winds and the first thunderstorms of the year.
Introduction Fall (autumn) and spring are transitional seasons, serving as bridges between the extremes of summer and winter. While both are periods of change characterized by moderate temperatures and shifting weather patterns, they move in opposite directions thermodynamically and symbolically. Fall represents a descent into dormancy and decay, whereas spring embodies emergence and renewal. This paper compares the meteorological, ecological, and psychological characteristics of the fall months (September, October, November in the Northern Hemisphere) and spring months (March, April, May). fall and spring months

Astronomically, fall begins with the autumnal equinox (around September 22-23), when day and night are nearly equal, after which nights grow longer than days. Spring begins with the vernal equinox (around March 20-21), after which days become longer than nights. Fall represents a descent into dormancy and decay,
