pywk99 is a python package for the wavenumber-frequency analysis of equatorial waves. The Library follows Wheeler, M., & Kiladis, G. N. (1999). Convectively coupled equatorial waves: Analysis of clouds and temperature in the wavenumber–frequency domain. Journal of the Atmospheric Sciences, 56(3), 374-399.
The library is provided without warranty and is still under early development, bugs in the code cannot be ruled out.
