- Parameters
- Grids: list
List of Py-ART Grids to visualize
- ax: matplotlib axis handle (with cartopy ccrs)
The axis handle to place the plot on. Set to None to create a new map. Note: the axis needs to be in a PlateCarree() projection.
- background_field: str
The name of the background field to plot the windbarbs on.
- level: int
The number of the vertical level to plot the cross section through.
- cmap: str or matplotlib colormap
The name of the matplotlib colormap to use for the background field.
- vmin: float
The minimum bound to use for plotting the background field. None will automatically detect the background field minimum.
- vmax: float
The maximum bound to use for plotting the background field. None will automatically detect the background field maximum.
- u_vel_contours: 1-D array
The contours to use for plotting contours of u. Set to None to not display such contours.
- v_vel_contours: 1-D array
The contours to use for plotting contours of v. Set to None to not display such contours.
- w_vel_contours: 1-D array
The contours to use for plotting contours of w. Set to None to not display such contours.
- wind_vel_contours: 1-D array
The contours to use for plotting contours of horizontal wind speed. Set to None to not display such contours.
- u_field: str
Name of zonal wind (u) field in Grids.
- v_field: str
Name of meridional wind (v) field in Grids.
- w_field: str
Name of vertical wind (w) field in Grids.
- show_lobes: bool
If True, the dual doppler lobes from each pair of radars will be shown.
- title_flag: bool
If True, PyDDA will generate a title for the plot.
- axes_labels_flag: bool
If True, PyDDA will generate axes labels for the plot.
- colorbar_flag: bool
If True, PyDDA will generate a colorbar for the plot background field.
- colorbar_contour_flag: bool
If True, PyDDA will generate a colorbar for the contours.
- bg_grid_no: int
Number of grid in Grids to take background field from. Set to -1 to use maximum value from all grids.
- barb_spacing_x_km: float
The spacing in km between each wind barb in the x direction.
- barb_spacing_y_km: float
The spacing in km between each wind barb in the y direction.
- contour_alpha: float
Alpha (transparency) of velocity contours. 0 = transparent, 1 = opaque
- coastlines: bool
Set to true to display coastlines
- gridlines: bool
Set to true to show grid lines.
- Returns
- ax: matplotlib axis
Axis handle to output axis
