Multi scale characteristics of Antarctic temperature change in January from 1982 to 2020
Antarctica is a sensitive area of global temperature change. Analyzing the temperature change in Antarctica can provide a basis for the analysis of global climate change The shared data provided by the automatic weather station plan are analyzed, and the relatively complete January temperature of An...

Antarctica is a sensitive area of global temperature change. Analyzing the temperature change in Antarctica can provide a basis for the analysis of global climate change The shared data provided by the automatic weather station plan are analyzed, and the relatively complete January temperature of Antarctic 8905 station from 1981 to 2020 is selected for analysis. Using the multi-scale analysis function of wavelet analysis, Morlet wavelet function is selected to carry out continuous wavelet transform on the daily temperature data, and the real part, modulus square and variance of continuous wavelet change are analyzed. It is found that the daily temperature of Antarctica is There are 14, 27, 72, 268, 380 and 665 day main periods for temperature changes. The trend analysis of wavelet transform coefficients under each period shows that the Antarctic temperature is in a high temperature period of 14, 27, 72, 268, 380 and 665 day periods in the years after 2021. The maximum temperature in January in Antarctica has a 20-year main period, and the minimum temperature has a 14-year and 23-year main period, The average value has a main cycle of 6 years, 14 years and 24 years. |
