meteoEVT - Computation and Visualization of Energetic and Vortical
Atmospheric Quantities
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>].
