Phenological characteristics of Tomb-Sweeping Day

Phenological characteristics: rainy in the south and dry and windy in the north.

The climate characteristics of the south of the Yangtze River can be described by a poem: "It rains in succession during the Qingming Festival". Generally speaking, during the Qingming period, the south is often cloudy and sunny, and abundant water can generally meet the needs of crop growth. What is annoying and can't be ignored is the harm of wet stains and poor lighting caused by too much rain.

During the period of Tomb-Sweeping Day, the temperature in some parts of the north rose rapidly and the rainfall was less, which was a dry and windy time in a year and also a time of dust. The average temperature in April in many northern areas has reached 10℃ ~ 15℃. Although the northeast and northwest regions of China have not yet entered the spring.

The origin of Qingming, what will Qingming do

Qingming is one of the twenty-four solar terms and the fifth solar term in spring. It will clear up when the sun reaches 15. During the Qingming period, the atmosphere was clear and everything appeared, hence the name. Qingming is a solar term that reflects the phenological changes in nature. Tomb-Sweeping Day is both a solar term and a festival, and Tomb-Sweeping Day atmosphere provides important conditions for the formation of Tomb-Sweeping Day customs in terms of time and weather phenology.

Tomb-Sweeping Day Qi, which is related to the phenology of 20 years old, is often used to guide farming, indicating that the weather is fine and spring ploughing is timely. Tomb-Sweeping Day is a day when people pay homage to their ancestors and pursue the future cautiously. Because of the integration of the two, Qingming has both natural and humanistic connotations. The main customs of Qingming are: sweeping graves, hiking, swinging, flying kites, planting trees and inserting willows.
