A method for analyzing short-term temperature fluctuations

Abstract

The invention relates to a method for analyzing short-term temperature fluctuations, which collects daily temperature series of a certain place for many years, takes data within the length of the research period to calculate the difference between the daily temperature and the temperature of the first day within the length of time, and forms a difference group , and form multiple difference series based on the corresponding difference group data for many years, sort each difference series by size, and calculate the upper and lower thresholds; determine the relationship between the daily corresponding difference group and the upper and lower thresholds of the corresponding difference series, It can be judged whether the temperature fluctuation occurs within the length of the study period. The method of the present invention can freely define the length of the research period and the threshold ratio of the occurrence of fluctuations, and eliminates the influence of seasonal changes on temperature fluctuations, and can obtain the daily temperature fluctuation range and the fluctuation frequency within a time period, and the direction of fluctuations can be determined by the fluctuation range Positive or negative indication of the indicator.

Description

technical field [0001] The invention belongs to the technical field of meteorological analysis, and in particular relates to a method for analyzing short-term temperature fluctuations. Background technique [0002] Temperature has always been a major focus in the field of climate research worldwide, and temperature change is a very important indicator of climate change. [0003] Since the phenomenon of climate warming has attracted people's attention, the research and control of temperature change has always been the focus of attention of various countries. In order to prevent the trend of global warming, the United Nations formulated the "United Nations Framework Convention on Climate Change" in 1992, which was signed in the Brazilian city of Rio de Janeiro in the same year. At the same time, since temperature changes (fluctuations) on different time scales help to understand large-scale global climate change, it has also become one of the hot topics in the field of climat...

AI Technical Summary

Problems solved by technology

The disadvantage is that it can only reflect the temperature fluctuation (deviation) range, and cannot identify the direction of temperature fluctuation (cooling or heating) and frequency

[0017] Previous temperature fluctuation analysis methods have their own limitations, and it is difficult to balance the length of the research period, the elimination of seasonal effects, and the availability of fluctuation indicators.

It is not only easy to set the length of the research period, but also eliminate seasonal effects, and can clearly judge the magnitude and frequency of temperature fluctuations, which is difficult to achieve by using a unified and existing temperature fluctuation analysis and calculation method
