Study a baroclinic perturbation in ECMWF data with plots of various meteorological diagnostics

Note 1 : This code was developed for educationnal purposes, and for French students. So the comments in the notebook are in French but the graphics and legends are in English.

Note 2 : If you have any comment/suggestion, if you find this code useful --> please send me an email : mailto:[email protected]

The data needed to run the notebook (MSLP, z, u, v, t, pv, w, q) are NOT provided. They can be downloaded here : https://www.ecmwf.int/en/forecasts/dataset/operational-archive

If you can't find the data ask me and I'll make it available for you.

With the notebook you will be able to compute and plot :

• Thickness
• Potential temperature
• Equivalent Potential temperature (Metpy function)
• Relative humidity (Metpy function)
• Geostrophic and agesotrophic winds
• Divergence
• Vorticity (relative/absolute)
• Potential vorticity
• Temperature advection
• Differential vorticity advection
• Interpolation of the isobaric potential vorticity on an isentropic surface (Metpy function)
• Gostrophic forcing and its convergence/divergence (Q1, Q2, div(Q))
• Frontogenesis and deformation field
