Matlab code for computing local wave activity (LWA) described in Chen et al. 2015.

• tracer_eq_1var_2d_local3.m: subroutine to compute local wave activity
• test_tracer_eq_local.m: sample script to run the local wave activity code with idealized wave perturbations

A fortran 90 version of the code is also available by email contact.

Example of LWA for European summer heat waves in 2003:
