easyclimate.plot.icon.plot_cell_barbs¶

easyclimate.plot.icon.plot_cell_barbs(ds, u_da, v_da, *, ax=None, lon_min=None, lon_max=None, lat_min=None, lat_max=None, center_lon=None, input_radians=True, lon_name_cell='clon', lat_name_cell='clat', nx_bins=35, ny_bins=20, thin_method='nearest_center', use_thinning_cache=True, transform=None, title=None, **barbs_kwargs)¶

Plot cell-centered vector wind as wind barbs on an ICON mesh.

ICON cell-centered vectors are thinned into regular longitude-latitude bins before they are passed to Axes.barbs. This keeps barb density readable on native ICON triangular meshes.

Parameters¶

dsxarray.Dataset: ICON dataset containing cell coordinate variables.
u_da, v_daxarray.DataArray or numpy.ndarray: Cell-centered zonal/eastward and meridional/northward vector components. Each input must be one-dimensional on ncells after selecting time or vertical dimensions.
axmatplotlib.axes.Axes, optional: Axes on which to draw. By default, use the current axes.
lon_min, lon_max, lat_min, lat_maxfloat: Plot extent in degrees. These bounds are required so vector thinning is restricted to the requested ICON domain.
center_lonfloat, optional: Longitude center used for wrapping. If None, infer it from the extent or valid cell centers.
input_radiansbool, default: True: If True, ICON longitude and latitude variables are interpreted as radians and converted to degrees.
lon_name_cell, lat_name_cellstr: ICON cell coordinate variable names.
nx_bins, ny_binsint, default: 35, 20: Number of longitude and latitude bins used to thin vectors.
thin_method{“nearest_center”, “max_speed”, “mean”}, default: “nearest_center”: Rule used to choose or aggregate one vector per bin.
use_thinning_cachebool, default: True: If True, cache coordinate-only bin metadata for repeated calls on the same ICON mesh and extent.
transformcartopy.crs.CRS, optional: Coordinate reference system of the input coordinates for Cartopy axes.
titlestr, optional: Axes title. If None, use a default wind-barb title.
**barbs_kwargs: Additional keyword arguments passed to Axes.barbs.

Returns¶

matplotlib.quiver.Barbs: Barb container returned by Axes.barbs.
