GRADIENT: The spatial rate of change of a quantity. Can you give examples?

3. 500hPa air temperature (February 2018) -- VALUE PLOTS

4. 500hPa air temperature (February 2018) -- VALUE PLOTS and CONTOUR

5. 500hPa air temperature (February 2018) -- CONTOUR (contour interval?)

6. 500hPa air temperature (February 2018) -- CONTOUR (contour interval?)

7. 500hPa air temperature (February 2018) -- CONTOUR FILLED (contour interval?)

8. 500hPa air temperature (February 2018) -- COLOR SHADED (contour interval???)

9. 500hPa air temperature (February 2018) -- COLOR SHADED (contour interval???)

10. 500hPa air temperature (February 2018) -- test contours and shades match value!

11. Where are the contours?
Where are areas of strong and weak gradients?
There are 2 displayed variables, but 3 display types.
What are the variables? Why 3 display types?

12. Here are a few guidelines in contour analysis:
Isopleths should never cross
Isopleths should not branch or fork
Only the area on the map that has data should be contoured
You should appropriately label your isopleths
