Method for correcting solar term climate period

Abstract

The invention discloses a correction method for a solar term climate period. The correction method comprises the following steps: S1, acquiring air temperature data by adopting a temperature sensor; s2, selecting air temperature data of a certain year, and obtaining a sequence of daily average values of a single station and a selected range; s3, performing data processing on the obtained average value sequence of the annual daily average temperature of the single site to obtain a daily temperature sequence of the single site and the selected range; and S4, drawing a daily air temperature sequence curve of 365 days according to the daily air temperature sequence, setting a solar term climate threshold value, determining a solar term starting day, a solar term ending day and a maximum value and a minimum value of a solar term interval air temperature sequence in an astronomical period, and judging and dividing the interval in which each solar term is located. According to the correction method for the climate time period of the solar term, the climate change degrees of different years, different regions and different solar terms can be accurately described, and the problem of how to quantitatively calculate the deviation between the climate time and the astronomical time in a solar term time system is fundamentally solved.

Description

technical field [0001] The invention relates to the field of climate, in particular to a method for correcting solar term climate periods. Background technique [0002] The twenty-four solar terms is an intangible cultural heritage of mankind originating from China. It is a time system commonly used by Chinese people to represent the climate state and rhythm. It is also a time system generally followed by many countries that inherit the twenty-four solar terms system. [0003] In the context of climate change, the inconsistency or even serious deviation between the climatic periods of the solar terms and the astronomical periods of the solar terms has increasingly affected the scientific application and cultural inheritance of the twenty-four solar terms by the public and society. People often lament that the twenty-four solar terms are becoming more and more inaccurate, and the guidance on agriculture and life based on the twenty-four solar terms is also becoming more and m...
