CH PhD Candidate Selected to Participate in DCMIP Workshop at NCAR

Kabir Rasouli, who is working towards his PhD at CH under the supervision of Prof. John Pomeroy, has been selected to participate in the 2016 DCMIP Workshop and Summer School at the National Center for Atmospheric Research (NCAR) scheduled June 6th – 17th.

From the DCMIP website –

Over the past fifty years, Earth-system models have given us incredible insight into the influence of the changing climate on regional and global scales. A major component of these models is the atmospheric dynamical core, which is responsible for solving the equations of fluid motion within the atmosphere. Substantial investments are now being made in the development of new dynamical cores at modeling centers around the world, driven by the need for more accurate and efficient models, the call for more practicable climate data at the fine scales, and the rapid growth of supercomputing architectures. More attention has been directed at inaccuracies and biases that arise due to the relatively crude division between physical parameterizations and dynamics. To better understand these systems, the Dynamical Core Model Intercomparison Project (DCMIP) aims to intercompare cutting-edge dynamical cores and provide a forum to exchange ideas and advance education on dynamical core development.

DCMIP will fund approximately 35 students and postdoctoral participants. Lectures from experts in the field on select topics associated with atmospheric model theory, design and development. Hands-on sessions run by model leads where students will execute and explore the newest generation atmospheric models. Students will receive hands-on experience with these dynamical cores in small groups to simulate a baroclinic instability, tropical cyclone and supercell storm.

CH Flood and Climate Change Research Profiled by Calgary Herald

The Calgary Herald of 18th June 2016 included an extended article covering convergent strands of CH research relating to climate-change, watershed processes and the 2013 Alberta floods.

The story described in detail how CH’s studies on topics as diverse as major declines in glacier ice in the high Rockies, the relative importances of forest-cover and soil properties in modulating suface runoff, changes in prairie rainstorm patterns and the increasing occurrence of previously unusual (and in some cases unprecedented) weather events have all helped to improve understanding of how flood events are likely to develop under changing climatic conditions.

The article is available for online viewing here, or as an archived PDF.

Rain on Snow Research Profiled in Rocky Mountain Outlook

Canmore’s Rocky Mountain Outlook has published an article describing interesting research by CH PhD candidate Nic Leroux and director Dr John Pomeroy. They have been exploring how rain which falls on late-season snowpack finds its way to the underlying surface, and their experiments have shown how this happens primarily along preferential flow paths or ‘flow fingers’. This holds great promise for improving understanding of the processes involved in rain-on-snow events, which have been occurring more frequently in the Alberta Rockies over recent years, and played a major role in the floods of 2013.

CH Comments on Role of Climate Change in Increasing Wildfire Risks

Following the major destruction wrought by the Fort McMurray wildfire at the beginning of May, and public interest in the factors which may have contributed to its ferocity, CH Director and Canada Research Chair in Water Resources and Climate Change Professor John Pomeroy was asked by Global News for his thoughts on this topic.

Dr Pomeroy highlighted research showing that conditions leading to low soil moisture and air humidity – such as those experienced throughout much of central and western Canada this spring following an extremely mild, dry winter – lead to an increased likelihood of major wildfires occurring. Many of the models developed to predict future fire behaviour under changing climatic conditions show such risks intensifying dramatically over future decades, particularly in the northern forests.

The interview is available for online viewing here.


PhD Student Awarded APEGS Grant

CH student Holly Anand, who is working towards her PhD on the topic of ‘Changing Prairie Hydrology’ under the supervision of Professors John Pomeroy and Howard Wheater, has been awarded a Member Grant of $7500  by the Association of Professional Engineers and Geoscientists of Saskatchewan (APEGS).

The award was made on the basis of Holly’s essay describing her accomplishments in the practice of engineering, service to the profession, reasons for pursuing grad studies and community involvement, supported by references from Professors John Pomeroy and Terry Fonstad. She will receive the award at the APEGS banquet in Saskatoon on the 7th of May.


CH Contributes Views on Possible Summer Drought Risks

CH’s Professor John Pomeroy has been interviewed by several Saskatoon media channels on the topic of likely water resources scenarios in the prairies this summer, following a warm, dry winter throughout much of the region.

The signs at this stage (mid April) are that western areas may be at particular risk of encountering drought-like conditions, with resultant impacts on agriculture and wildfire risks.

Prof. Pomeroy commented that “Large evacuations due to forest fire are occurring almost every year in western Canada now, when they used to be much rarer occurrences”.

CH Model Contributes to UNESCO Andean Hydrological Training in Chile

The UNESCO International Hydrological Programme Course on Professional Training on Andean Hydrology held in Santiago, Chile, 17-20 November 2015 featured hydrological model training using the U of S’s Cold Regions Hydrological Model (CRHM) – taught by Dr James McPhee and PhD student Yohann Videla Giering, both of the University of Chile.

The course was taught to 52 students from Chile, Bolivia, Peru, Costa Rica, Mexico, Brazil, Belgium, Dominican Republic, Argentina and Germany. Dr McPhee is a collaborator with UofS in the field of mountain hydrology and water resources. Yohann Videla Giering is now on a Chilean Government-funded exchange spending 6 months with the University of Saskatchewan Centre for Hydrology (GIWS) where he is learning how to apply the new glacier hydrology components of CRHM (developed as part of CCRN) to calculate the water resources of the Andes.

CH Provides Insights on Wider Implications of Warm Spring Conditions

Prof. John Pomeroy – in his capacity as Canada Research Chair in Water Resources and Climate Change – was recently asked by two media outlets for his thoughts on the science behind this year’s warm winter and spring.

Saskatoon’s StarPhoenix newspaper published an article considering the links between these historically highly unusual (and in some cases unprecedented) conditions, global climate change, and what may yet turn out to be the strongest El Niño on record. It also looked at what they may portend for the risks of floods, drought and wildfires during the approaching summer.

Similar points were covered by local radio station News Talk 650.

The news article is available from its original source here, and as a downloadable PDF: the radio piece is described here.

CH Members Contribute to National Post Article on Climate Change Impacts

CH director Professor John Pomeroy and CH fellow Mike Demuth (Geological Survey of Canada) have contributed to an article in the National Post outlining ways in which the effects of climate-change may be felt across Canada. The piece considers likely changes in temperature, precipitation, glacial cover, water resources, distributions of vegetation and wildlife and some related socio-economic issues.

The article is available here. Please note that early versions misquoted Prof. Pomeroy: the related passage should read as follows;

The extra rain, for example, is unlikely to fall in a gentle spring shower. Look for it in great flooding downpours or winter rains that drain before they can nourish crops.

John Pomeroy, a Canada research chair in water resources at the University of Saskatchewan, points out the amount of water that falls as snow has already declined by one-third on the Prairies. The number of multi-day rains has increased by half.

“Farmers need to adapt to that, to being inundated and flooded quite a bit,” he said.
