python package to compute finite-amplitude local wave activity (Huang and Nakamura 2016, JAS)
hn2016_falwa is a package that contains modules to compute the finite-amplitude local wave activity (FALWA) proposed in Huang and Nakamura (2016 JAS): http://dx.doi.org/10.1175/JAS-D-15-0194.1 The current version of the library handles calculation of FALWA in a spherical barotropic model and QGPV fields on isobaric surfaces.
The functions in this library can compute the tracer equivalent-latitude relationship proposed in Nakamura (1996) (Also, see Allen and Nakamura (2003)) and the (zonal mean) finite-amplitude wave activity in spherical geometry as in Nakamura and Solomon (2010).
A bug is fixed in version 0.1.3. The differential line element in lwa.py should be a vector instead of a scalar.
