North and Central America Climate Forum 11may 2021

The World Climate Research Programme (WCRP) local organizing committee for the North and Central America, Caribbean, and Greenland region warmly invite you to the upcoming WCRP Climate Research Forum on “Climate research priorities for the next decade.”

This Forum will begin with an overview of WCRP from the Chair and Vice Chair of the WCRP Joint Scientific Committee (the scientific steering body of WCRP), Detlef Stammer and Helen Cleugh, followed by three invited talks on:

  1. Perspectives on the role, benefits and science imperatives of the WCRP
    • Climate information needs from a user/policy maker perspective. Roberto Sánchez-Rodríguez, El Colegio de la Frontera Norte, Mexico.
    • Earth system observations for assessing climate-related risks. Susann Tegtmeier, University of Saskatchewan, Canada.
    • Advances and challenges in global and regional climate modeling. Andreas Prein, National Center for Atmospheric Research, United States.

This will be followed by a moderated discussion session that will include short presentations on:

  1. Collaboration activities in the region
    • The Precipitation Prediction Grand Challenge. Louis W. Uccellini, National Weather Service, United States.
    • Understanding and Predicting Water Futures in an Era of Global Change. John Pomeroy, University of Saskatchewan, Canada.
    • IAI’s strategic priorities in global change research, with a focus on climate and water. Anna Stewart, Executive Director, Inter American Institute for Global Change Research (IAI).
    • The changing cryosphere in a warming climate. Dorthe Dahl-Jensen, Niels Bohr Institute, University of Copenhagen, Denmark, and the Centre for Earth Observation Science, University of Manitoba, Canada.

The Forum is open to all, please register here.

Announcement: Workshop on ‘Attribution of multi-annual to decadal changes in the climate system.’ 22-24 Sept 2021

We would like to bring to your attention the WCRP Explaining and Predicting Earth System Change Lighthouse Activity Workshop on ‘Attribution of multi-annual to decadal changes in the climate system.’ The workshop will take place online, from 22-24 September 2021. 

The aim of this workshop is to document current research, identify challenges, and explore potential pathways towards building an operational capability to attribute multi-annual to decadal changes in the climate system on global-to-regional scales. The attached first circular gives an overview of the key areas that will be addressed during the workshop. A second circular with registration details will be issued towards the end of April.

New: improved Fortran and Python decoding programs for high vertical-resolution radiosonde data

In SPARC Newsletter number 56, Geller et al. (2021) described increased high vertical-resolution radiosonde data that is now available to the global research community, and in that article they described how to access those data. Mr. Bruce Ingleby has now developed improved Fortran and Python decoding programs for those data. They can be accessed from https://confluence.ecmwf.int/display/ECC/bufr_read_tempf ‘. Future developments will be described as they become available.

Announcement: WCRP Open Science Conference: early 2023

Dear colleagues,  
  
We are delighted to share with you the First Circular of the WCRP Open Science Conference, to take place in early 2023 (download flyer). This conference will showcase the work that all of you are doing, right across WCRP and with partners. In particular, it will highlight the importance of climate science for decision-making and responding to a changing climate. This Conference will, of course, celebrate the work of the WCRP Grand Challenges, which will sunset at the end of 2022. At the same time, it will roll out the new WCRP and will be dedicated to the next generation of climate scientists. It will also include events that cater to the general public.   
  
In the next weeks and months we will continue with the planning of the conference, including identifying a host for the in-person part of the meeting and the establishment of a science planning committee. Conference planning will be supported by dedicated staff who will be hired specifically for this purpose using external funds.  
  
Kind regards  
  
Detlef Stammer and Helen Cleugh
