Tilt of earth’s axis: The Earth's axis is tilted at an angle of ~23.5 degrees relative to its orbit around the Sun. This tilt results in variations in the amount of sunlight different regions receive at different times of the year.
Earth’s revolution: As the Earth revolves around the Sun, different parts of the Earth receive varying amounts of solar energy. This leads to the changing of seasons.
Latitude and regional variations: In summer and winter solstices specific latitudes receive maximum and minimum sunlight. Equinoxes, mark periods when day and night are approximately equal in duration.
Seasonal shifts in temperature and pressure: Shifts in temperature and pressure zones result in development of distinct seasons, with warmer temperatures in summer and cooler temperatures during winter.
Wind system: In regions such as Indian subcontinent, monsoon winds play a crucial role in seasonal changes. The southwest monsoon, originating from the Indian Ocean, brings the rainy season during summer, while the northeast monsoon influences the post-monsoon season.
