Configuring a Sounding and Hodograph Display - OCLO

Purpose:

Tasks:

Assumptions:

• A RAOB or a point model sounding is loaded in NSHARP.

1. In the NSHARP control buttons window: left-click on the Configure button and then left-click the Parameters Selection button to launch the NSHARP Parameters Selection GUI.                                                                           
2. In the NSHARP Parameters Selection GUI: left-click on the text or radio button for each of the following parameters: Mixing Ratio, Moist Adiabat, and Cloud.
3. When you toggle on/off parameters in the GUI, the display will automatically update to reflect those changes.
4. In the Temperature Range Offset entry, type in -20 and left-click the Apply button.
   • Notice the SkewT shift to display colder temperatures (can be handy with colder soundings).
5. In the Temperature Range Offset entry, type in 0 and left-click the Apply button to restore the default temperature axis.
6. In the Sounding Comp Radius (mile) entry, type in 50 and left-click the Apply button to allow soundings from different sources to load together when they are within 50 miles of each other.
7. Left-click the Apply button and then the Close buttons on both the Nsharp Parameters Selection and Nsharp Configuration windows.
8. From the Tools menu, select Points.
9. Left-click and hold on a point and drag the point to near the location of the RAOB (within 50 miles).
10. From the Volume menu, select Browser.
11. In the Volume Browsers GUI, left-click on the menu just to the right of the Tools menu (e.g. “Plan view” if the previous use was Plan view) and select Sounding.
12. Under Sources: from the Volume menu select RAP40.
13. Under Fields: from the Thermo menu select Sounding.
14. Under Planes: from the Points menu, select D2D Points, then select your sounding point (e.g., “Sounding A”).
15. Swap the pane containing your RAOB, so the RAOB is displayed in the main panel before loading the Volume Browser sounding.
16. Left-click on the Load button at the bottom of the Volume Browser GUI.
17. Compare the two sounding sources
    1. In the NSHARP window, left-click on the CompSrc() button.
       • This is a handy way to compare model intializations with observed RAOBs.
       • If you try to use a point outside 50 miles, there will be no comparison overlay between the two soundings.
    2. In the NSHARP window, left-click on the CompSrc().
       • This will toggle the CompSrc() off. This is essential for allowing the configurations in the next step.
18. In the NSHARP window, left-click on the Configure button.
19. In the NSHARP Configuration GUI (launched from the Configure button), left-click on the Data Display Configuration button.
20. Left-click on the drop-down menu in the top-left corner of the GUI, then left-click on the Virtual Temp option.
21. Change the Color, Width, and Style of the Virtual Temp line by left-clicking over a color/width/style option.
    • The settings will be applied for the rest of the CAVE session. They are only permanently saved to your account if you save the settings with the Save button.
22. Left-click the Apply button (do not Save) to view your changes in the Skew-T display.
    1. Select the Close buttons in the Nsharp Data Display window and Nsharp Configuration window.
23. Revert to the original Color, Width, and Style of the Virtual Temp line by making color/width/style selections (should be red, dashed, medium thickness) in the Nsharp Data Display, and left-click the Apply button.
    • Alternatively, restart CAVE when done to revert to original settings
24. Task Complete!
