Wavelet Analysis of Average Monthly Temperature New Delhi 1931- 2021 and Forecast until 2110

Wavelet Analysis of Average Monthly Temperature New Delhi 1931- 2021 and Forecast until 2110 DOI: https://doi.org/10.30564/jasr.v6i2.5447 Abstract The identification method in the CurveExpert-1.40 software environment revealed asymmetric wavelets of changes in the average monthly temperature of New Delhi from 1931 to 2021. The maximum increment for 80 years of the average monthly temperature of 5.1°C was in March 2010. An analysis of the wave patterns of the dynamics of the average monthly temperature up to 2110 was carried out. For forecasting, formulas were adopted containing four components, among which the second component is the critical heat wave of India. The first component is the Mandelbrot law (in physics). It shows the natural trend of decreasing temperature. The second component increases according to the critical law. The third component with a correlation coefficient of 0.9522 has an annual fluctuation cycle. The fourth component with a semi-annual cycle shows t...
