  "Description": "Energy-Vorticity theory (EVT) is the fundamental theory to\ndescribe processes in the atmosphere by combining conserved\nquantities from hydrodynamics and thermodynamics. The package\n'meteoEVT' provides functions to calculate many energetic and\nvortical quantities, like potential vorticity, Bernoulli\nfunction and dynamic state index (DSI) [e.g. Weber and Nevir,\n2008, <doi:10.1111/j.1600-0870.2007.00272.x>], for given\ngridded data, like ERA5 reanalyses. These quantities can be\nstudied directly or can be used for many applications in\nmeteorology, e.g., the objective identification of atmospheric\nfronts. For this purpose, separate function are provided that\nallow the detection of fronts based on the thermic front\nparameter [Hewson, 1998, <doi:10.1017/S1350482798000553>], the\nF diagnostic [Parfitt et al., 2017, <doi:10.1002/2017GL073662>]\nand the DSI [Mack et al., 2022, <arXiv:2208.11438>].",
