MetPy 0.7.0 has been released:
API Changes
- The default dimension ordering for functions in
kinematics(i.e. whendim_orderis not passed) has changed from "xy" to "yx". This lets more data work out of the box with these functions, and has been warned since 0.5.1 - Renamed
h_convergenceandv_vorticitytodivergenceandvorticity, respectively. These latter names are simpler and more accurate. The old names are still available for old code, but are deprecated and will be removed in 0.9. convergence_vorticityandshearing_stretching_deformationare deprecated, and will be removed in 0.9. These functions existed as performance optimizations, but new calculation internals renders them unnecessary.- The parameter
sblclforsignificant_tornadohas been renamed tosurface_based_lcl_heightto improve clarity. This only affects users who were passing by keyword argument. - Changed
relative_humidity_wet_psychrometric,relative_humidity_from_mixing_ratio, andrelative_humidity_from_specific_humidityto return values as unitless ratios rather than percentages, for better symmetry with the rest of the library.
Highlights
- Added our own functions for
first_derivative,second_derivative,gradient, andlaplacian. These are 3 point finite difference calculations that handle irregularly spaced grid points. - Added function to calculate x,y grid spacing for latitude/longitude grids
- Added table of equivalencies between GEMPAK functions and Python. This is an on-going effort to provide a resource for migrating from GEMPAK.
- Added ability to
add_timestampto add outlined text - New calculations
- Thickness (using hypsometric formula)
- Geopotential to/from height
- Mixing ratio from relative humidity
- Moist static energy
- Dry static energy
