UKCP09 projections - Stratification Changes (medium emissions, 2080-2090 projections)

What is it: 

These layers show a sub-set of the UKCP09 marine and coastal projections up to 2090s (see layer name for date) using a medium emission scenario and, where appropriate, medium probability. The sub-set chosen are considered to be most relevant to marine planning and management in Scottish waters. The full suite of projections, and all emissions scenarios, can be found on the UKCP09 web site.  An update of the UKCP09 data outputs is planned for 2018.

There are two layers available for Stratification Changes:

  1. Change in Start Date of Stratification
  2. Change in Total Number of Stratified Days

More Information: 

UKCP09 is the name given to the UK Climate Projections. The UKCP09 website allow users to access information on plausible changes in 21st century climate for the United Kingdom. UKCP09 provides future climate projections for land and marine regions as well as observed (past) climate data for the UK.

UKCP09 was produced in 2009. It is based on sophisticated scientific methods provided by the Met Office, with input from over 30 contributing organisations. UKCP09 can be used to help organisations assess potential impacts of the projected future climate and to explore adaptation options to address those impacts.

Summarising the anticipated changes around Scotland based on central estimate projections for 2080-90 using the medium emission scenario:

Stratification - projected will start earlier possibly by as much as 5 to 10 days. However, there are exceptions to this pattern, such as in the Tay / Forth area, west of the Hebrides, and some other local inshore areas. In the offshore waters, stratification will end later in the year, by possibly as much as 10 to 15 days. In inshore waters again there is quite a complex pattern in the projected changes. The length of the stratified period in offshore waters is generally 10-15 days longer than currently, with some local, inshore variation.
