Summer mean relative humidity

These maps are useful to communicate the main results of UKCP09 and raise awareness about climate change. When presenting UKCP09 projections using maps you should use a series of maps to show the range of possible outcomes. Here you will find maps showing outcomes at the 10%, 33%, 50%, 67% and 90% probability levels. They are presented for the 2020s, 2050s and 2080s and for low, medium and high emissions scenarios.

To download the maps, simply click on them and save to your computer. When using in presentations or reports, please credit these images as: © UK Climate Projections 2009

If you would like to edit the parameters used to create these maps and generate your own image, you can do so by clicking 'link to customisable version' above the map you would like to edit. This will take you to the User Interface, which requires a login.

If you require a postscript version of an image for high-resolution printing, please contact the Helpdesk with details of which image, and where it is to be used.
