On completion of this topic you will be able to:

  • Compare different General Circulation Models for percent change in precipitation and changes in degrees C of temperature.
  • Find values for places.


Site specific climate change scenarios are important when assessing local change. The numeric outputs for specific places are defined by clicking on a location or through entry of latitude and longitude information provides specific outputs for specific places on a per degree C change value. Like spatial scenario and with other SimCLIM 4.x for Desktop tools the user defines the General Circulation Model and RCP parameters.


Be sure to have a study area selected.

To open the site specific scenario generator click on the Site Specific Scenario Generator icon from the main toolbar on the top of the screen or right click in the main screen and select the icon from all those presented.

Choose Climate Change (we will look at sea level later).

Move from the top of the dialogue box to the bottom selecting the variables as you go.

Depending of the study area chosen an image similar to one below will be displayed:

Click on Apply and a map of the study area selected will be displayed.

Some tips before proceeding . . .

1] Site specific results can also be displayed by left clicking on any site in the map.

2] You can also enter the latitude and longitude for a site if it is within the boundaries of the map.

3] You can leave a graph open, return to the dialogue box, change a climate change parameter, load the data and open another graph for comparison.

4] Graphs can be copied to the clipboard using the clipboard tool.

5] You can choose to replace the map when you choose a new GCM pattern or you can choose to open a new window with the new GCM pattern for comparative purposes.

6] The tabular information can be saved and exported by right clicking on the data and choosing from the options, including exporting to Excel.

Activity: Conduct analysis for precipitation, Tmin, Tmean and Tmax for your chosen study area. Run different scenarios and compare the graphic outputs. Save the tabular data in different formats

Normalized GCM Patterns

By clicking on the in the site specific scenario generator a number of very useful values is displayed for that site.

Review the table with the group and your instructor and consider how the outputs from this table can inform your investigation.
