A season is a subdivision of the year, marked by changes in weather, ecology, and hours of daylight. Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to go into hibernation or to migrate, and plants to be dormant.
During May, June and July, the northern hemisphere is exposed to more direct sunlight because the hemisphere faces the sun. The same is true of the southern hemisphere in November, December and January. It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux. However, due to seasonal lag, June, July and August are the hottest months in the northern hemisphere and December, January and February are the hottest months in the southern hemisphere.
In temperate and subpolar regions, generally four calendar-based seasons (with their adjectives) are recognized: spring (vernal), summer (estival), autumn (autumnal) and winter (hibernal). However, ecologists mostly use a six season model for temperate climate regions that includes pre-spring (prevernal) and late summer (serotinal) as distinct seasons along with the traditional four.
Hot regions have two or three seasons; the rainy (or wet, or monsoon) season and the dry season, and in some tropical areas, a cool or mild season.
In some parts of the world, special "seasons" are loosely defined based on important events such as a hurricane season, tornado season or a wildfire season.
Famous quotes containing the word season:
“Compare ... the cinema with theatre. Both are dramatic arts. Theatre brings actors before a public and every night during the season they re-enact the same drama. Deep in the nature of theatre is a sense of ritual. The cinema, by contrast, transports its audience individually, singly, out of the theatre towards the unknown.”
—John Berger (b. 1926)
“Utterly frozen is this youthful lady,
Even as the snow that lies within the shade;
For she is no more moved than is the stone
By the sweet season which makes warm the hills”
—Dante Alighieri (1265–1321)
“The theater is a baffling business, and a shockingly wasteful one when you consider that people who have proven their worth, who have appeared in or been responsible for successful plays, who have given outstanding performances, can still, in the full tide of their energy, be forced, through lack of opportunity, to sit idle season after season, their enthusiasm, their morale, their very talent dwindling to slow gray death. Of finances we will not even speak; it is too sad a tale.”
—Ilka Chase (1905–1978)
