Meteorologically, autumn is characterized by a steady decline in temperature. The air often feels "crisp" or "brisk" due to a drop in humidity and the arrival of cool polar air masses. This transition typically brings a mix of mild, sunny afternoons and frost-nipped mornings, creating the perfect climate for layered clothing and outdoor harvests. 4. Preparation for Dormancy
Autumn has significant cultural and symbolic meaning in many societies. In many cultures, autumn is a time of thanksgiving and harvest festivals, celebrating the bounty of the land and the hard work of farmers. For example, the American Thanksgiving holiday is celebrated in autumn, while the Chinese Mid-Autumn Festival is a significant holiday that marks the full moon and the harvest season. characteristics of autumn season

The "golden hour" takes on a different quality in autumn. Because the sun is lower on the horizon, sunlight travels through more of the Earth's atmosphere, scattering blue light and emphasizing soft, golden, and warm tones. Additionally, the season is often associated with increased wind and rain as atmospheric pressure systems shift toward winter patterns. 7. Cultural and Psychological Shifts
During autumn, the average temperature decreases as the Earth's axis tilts away from the sun. This results in shorter days and cooler nights, with temperatures ranging from mild to cold. Weather patterns during autumn are often unpredictable, with warm and cold fronts alternating, leading to rain, wind, and sometimes even snow.
