1. Project Details
Title | Type the title of your project. This information will appear on the results page. |
Year | Click the small arrow to display the drop-down list of years. These represent the mid-point of a 20-year time period (e.g. “2050” represents the period 2040 – 2059). |
Scenario | Choose the greenhouse gas scenario to suit your needs. There are two groups of scenarios:
|
2. Variable Selection
Choose the variables... | Tick the box corresponding to each variable that affects the system you are studying. Please note though, that if you choose wind speed in addition to temperature and rainfall (or related variables) you should use the wind projections with caution as they may not adequately sample the range of wind results. (Note that more variables are available using the Detailed Projections tool) |
Choose the seasons... | Tick the boxes to select the season or seasons for which projections are needed. Note that selecting more seasons will slow down the generation of the projections results. (More seasons are available using the Detailed Projections tool.) |
3. Region Selection
As with the Future Climates interface, click on the map to select the region of interest to your assessment. You will then be presented with page two of the Projections Builder (Figure 3).
Projections Builder: Page 2
Page two asks you to use your knowledge of the influence of each climate variable on the system you are studying to define the best and worst case. The amount of detail available to make these choices will vary. However, limited information or expert judgement can also be used to guide this process (in the absence of better information).
...
When you are happy with the settings, make a record of how you defined the cases (e.g. by printing the page). Once you have done this, click the Next button. There will be a delay while Climate Futures calculates your results and it may appear that nothing is happening. The more variable/season combinations you are using, the longer it will take – please be patient.
