Four Seasons In The World ((top)) -

(used by climatologists) divide the year into three-month periods based on temperature cycles, which align more neatly with monthly averages:

Not all regions experience four distinct seasons: four seasons in the world

However, from a geophysical perspective, the "four seasons" are not a global standard but a specific result of the Earth’s axial tilt relative to its orbit around the Sun. This paper aims to explore the scientific mechanisms behind the seasons, examine how they manifest differently across various latitudes, and discuss the limitations of applying a four-season model to tropical and polar environments. By doing so, we can better understand the diversity of the world’s climatic behaviors. (used by climatologists) divide the year into three-month

| Season | Northern Hemisphere Months | Southern Hemisphere Months | Key Global Features | |--------|----------------------------|----------------------------|----------------------| | Spring | March, April, May | September, October, November | Blooming, warming, equinox | | Summer | June, July, August | December, January, February | Longest days, peak heat | | Autumn | September, October, November | March, April, May | Cooling, leaf fall, harvest | | Winter | December, January, February | June, July, August | Coldest, shortest days | | Season | Northern Hemisphere Months | Southern

The four seasons are primarily caused by the (approximately 23.5 degrees) and its orbit around the Sun. As Earth travels around the Sun, different hemispheres receive varying amounts of direct sunlight.
