Cross-section plots

Like the contour plots, PostWRF provides a combination of three variables to be overlaid
in a cross-section plot, besides the path of cross-section in a separate small plot inside the main plot

Note

Line colors, font sizes, etc., can be modified by changing the relevant variables in namelist.wrf

Example 1

A set of line contours with the path of the cross-section:

============= CROSS SECTION PLOT ==============
===========================================
CROSSSECTION_ON-OFF = 1
CrossSection_path_on_off = 1
Topographic_map_on_off = 1
!!! 3D Variable_1 by line contours !!!
1st_var_on_off = 1
1st_var_name = rh
1st_var_intervals = 20
1st_var_line_color = blue
1st_var_line_thickness = 0.5
1st_var_label_size = 0.4
!!! 3D Variable_2 by (broken) line contours !!!
2nd_var_on_off = 0
2nd_var_name = (ua^2 + va^2)^0.5
2nd_var_intervals = 4
2nd_var_line_color = black
2nd_var_line_thickness = 0.5
2nd_var_label_size = 0.5
2nd_var_brokenline_on_off = 1
!!! 3D Variable_3 by filled (colored) contours !!!
3rd_var_on_off = 0
3rd_var_name = pvo
————————————————————————————————-

Output image at a specific time-slot in the WRF output is as bellow:

Example 2

A set of line contours of a polynomial and a set of shaded contours, besides the path of the cross-section

============= CROSS SECTION PLOT ==============
===========================================
CROSSSECTION_ON-OFF = 1
CrossSection_path_on_off = 1
Topographic_map_on_off = 0
!!! 3D Variable_1 by line contours !!!
1st_var_on_off = 0
1st_var_name = rh
1st_var_intervals = 20
1st_var_line_color = blue
1st_var_line_thickness = 0.5
1st_var_label_size = 0.4
!!! 3D Variable_2 by (broken) line contours !!!
2nd_var_on_off = 1
2nd_var_name = (ua^2 + va^2)^0.5
2nd_var_intervals = 4
2nd_var_line_color = black
2nd_var_line_thickness = 0.5
2nd_var_label_size = 0.5
2nd_var_brokenline_on_off = 1
!!! 3D Variable_3 by filled (colored) contours !!!
3rd_var_on_off = 1
3rd_var_name = tc
