What is PCPI?

The Polar Climate Predictability Initiative (PCPI) is an initiative of the World Climate Research Programme (WCRP), whose goal is to improve the understanding of the predictability of climate and the effect of human activities on climate. The PCPI has a focus on polar regions and their role in the global climate system, and aims to improve predictability of the climate system on all time scales by improving our understanding of the underlying physical mechanisms and their representation in climate models.

The PCPI will accomplish this task by co-ordinating the efforts of the international science community, bringing together the different elements of the WCRP, and working closely with other international agencies such as the World Weather Research Programme's Polar Prediction Project (WWRP - PPP). The focus here is not on prediction of the climate system, but instead on finding elements of the climate system that contribute to predictability, and how these processes may be improved in models.

The PCPI complements existing efforts by bringing together expertise on the modelling aspects of the climate. It is an initiative of the WCRP under the the Grand Challenge "Cryosphere in a Changing Climate".

The PCPI is supported by the Climate and Cryosphere Project (CliC) and Stratosphere-troposphere Processes And their Role in Climate Project (SPARC), two core projects of the WCRP.

Summary: PCPI Leads Meeting in Reading

pcpibanner 2015The theme Leaders and Chairs of the Polar Climate Predictability Initiative (PCPI) met 9-11 September 2015, at the University of Reading in the UK. They discussed PCPI activities that have taken place since their previously meeting in April 2014. They heard about numerous journal articles (both published and in preparation) that arose from PCPI activities, two successful workshops, and several sessions at major Conferences (AGU, EGU, IUGG). They also brainstormed about future activities and ways that PCPI can contribute to joint activities with other international groups, such as the Polar Prediction Project (PPP) and CliC. Four attendees involved in organizing the joint WWRP/WCRP/Bolin Centre School on Polar Prediction sought input about the agenda and design of lab activities. The PCPI Leaders and Chairs discussed the Year of Polar Prediction (YOPP), and in particular they realized that they could help encourage measurement campaigns already planned (especially those in the Antarctic) to contribute to YOPP. They explored ways that PCPI could expand their network of scientists, especially by involving early career scientists in their leadership team and in activities. They would like to create PCPI fellows, modeled after the CliC fellows.
