# Joint Probability Plots

Joint probability plots show the relative probability of projected changes in one climate variable against the projected changes in another. You can produce them in the UKCP09 User Interface by using the sampled model output.

They are useful if you need to compare the probability of a specific combination of changes occurring between two climate variables.

You can produce joint probability plots for the climate change projections and the marine & coastal projections to show projected climate change or projected future climate for:

- Two climate variables (such as temperature and precipitation)
- One location
- One time period
- One temporal average
- One emissions scenario
- Probability contours (to indicate the relative probability of different joint occurrences).

You can export joint probability plots from the UKCP09 User Interface as images in various file formats (.pdf, .ps .png and .jpg). The underlying values can be exported as a .csv files which can be opened as a spreadsheet.

## More information on joint probability plots

More information about how to use the graphs can be found on the 'Joint probability plots in detail' page. Information on how to interpret the graphs can be found on the 'Interpreting joint probability plots' page.
