%description
Energy-Vorticity theory (EVT) is the fundamental theory to describe
processes in the atmosphere by combining conserved quantities from
hydrodynamics and thermodynamics. The package 'meteoEVT' provides
functions to calculate many energetic and vortical quantities, like
potential vorticity, Bernoulli function and dynamic state index (DSI)
[e.g. Weber and Nevir, 2008, <doi:10.1111/j.1600-0870.2007.00272.x>], for
given gridded data, like ERA5 reanalyses. These quantities can be studied
directly or can be used for many applications in meteorology, e.g., the
objective identification of atmospheric fronts. For this purpose, separate
function are provided that allow the detection of fronts based on the
thermic front parameter [Hewson, 1998, <doi:10.1017/S1350482798000553>],
the F diagnostic [Parfitt et al., 2017, <doi:10.1002/2017GL073662>] and
the DSI [Mack et al., 2022, <arXiv:2208.11438>].
