We investigate the impact of local climatic variations on the energy performance of buildings by conducting simulations using weather files generated from high-resolution measurements covering 33 stations within a 77 km² area in southern Vancouver Island, British Columbia, Canada. Weather files were created by resampling the data and applying appro...

In the recent decades computing systems have become ubiquitous in our daily life. Due to wear and tear, limited component lifetime, and extraneous factors, among other reasons, all of the systems that we design and implement are subject to failure. One of the main areas in the field of fault tolerance, system evaluation, is concerned with the analy...

We evaluate the capacity of a regional climate model to simulate the statistics of extreme events, and also examine the effect of differing horizontal resolution, at the scale of individual hydrological basins in the topographically complex province of British Columbia, Canada. As described in a companion paper (Curry, C. L., Tencer, B., Whan, K.,...

We evaluate the capacity of a regional climate model to represent observed extreme temperature and precipitation events and also examine the impact of increased resolution, in an effort to identify added value in this respect. Two climate simulations of western Canada (WCan) were conducted with the Canadian Regional Climate Model (version 4) at 15...

Modern-day coral reefs have well defined environmental envelopes for light, sea surface temperature (SST) and seawater aragonite saturation state (Ωarag). We examine the changes in global coral reef habitat on multimillennial timescales with regard to SST and Ωaragusing a climate model including a three-dimensional ocean general circulation model,...

Climate models indicate that warming due to increase in shortwave absorption from the lowering of albedo caused by afforestation reduces and can even overcome, particularly at high latitudes, the cooling caused by the carbon drawdown. We use high resolution (0.05 × 0.05° to 1 × 1°) global satellite observations to investigate the effects of affores...

The results from two climate model simulations are used to explore the relationship between North Atlantic sea surface temperatures and the development of African aridity around 100,000 years ago. Through the use of illustrative simulations with an Earth System Climate Model, it is shown that freshwater fluxes associated with ice sheet surges into...

The impacts of rapid climate change likely influenced human behaviour during the last glacial cycle, potentially stimulating habitation of, and migration along, continental shelves exposed during periods of lowered sea level. Last glacial maximum (LGM) climate model simulation shows cooler surface air temperatures in Eastern Beringia than Western a...

"At the fall CAP Council meeting, Pedro Goldman of UWO, Chair of the Division of Physics Education (DPE), spoke strongly to draw attention to the serious decline in undergraduate enrolments in physics. He pointed out that this is a major threat to the health of physics in Canada, and proposed a preliminary study to better understand the factors und...

(1) The response of the thermohaline circulation (THC), as well as the freshwater and heat budgets of the northern North Atlantic, to above-normal sea ice export from the Arctic is examined using a global model. The model is not constrained by either open boundary conditions or prescribed atmospheric air temperature and humidity. Two sets of experi...

[1] Between 20 and 80 kyr ago several cooling cycles occurred in the Northern Hemisphere which culminated in a discharge of icebergs into the North Atlantic. These so called "Heinrich Events'' (HEs) were followed by an abrupt shift to a warmer climate. Here we use a coupled ocean-atmosphere-sea ice model to study the response of the climate system...

The climate modelling group at the University of Victoria is involved in research in the fields of climate and paleoclimate modelling, dynamics and variability using a coupled atmosphere, ocean and sea ice model. Typically the computational cost of running such models prohibits running them to equilibrium. For this reason a model was recently devel...

A new earth system climate model of intermediate complexity has been developed and its climatology compared to observations. The UVic Earth System Climate Model consists of a three-dimensional ocean general circulation model coupled to a thermodynamic/dynamic sea-ice model, an energy-moisture balance atmospheric model with dynamical feedbacks, and...

The most common method used to evaluate climate models involves spinning them up under perpetual present‐day forcing and comparing the model results with present‐day observations. This approach clearly ignores any potential long‐term memory of the model ocean to past climatic conditions. Here we examine the validity of this approach through the 600...

An ocean general circulation model coupled to an energy-moisture balance atmosphere model is used to investigate the sensitivity of global warming experiments to the parametrisation of sub-grid scale ocean mixing. The climate sensitivity of the coupled model using three different parametrisations of sub-grid scale mixing is 3°C for a doubling of CO...

A coupled model of intermediate complexity is used to examine the importance of the parameterisation of sub-grid scale ocean mixing on the global mean steric sea level rise in global warming simulations. It is shown that when mixing associated with mesoscale eddies is treated in a more physically realistic way than the commonly used horizontal/vert...

A coupled atmosphere-ocean-sea-ice model is used to investigate the climate of the Last Glacial Maximum (~21,000 years ago) and the relative climate-forcing effects of atmosphere CO2, the Earth's orbital parameters and ice-sheet albedo. Tropical temperatures are found to be ~2.2°C less than today's-slightly colder than indicated by the CLIMAP palae...

High river temperatures have been linked to pre‐spawning mortalities in salmon returning to their natal streams. As a first step in predicting these temperatures, flow and temperature models were developed for the Fraser and Thompson Rivers in British Columbia. The flow model is essentially pre‐calibrated while the temperature model was calibrated...

Climate models indicate that warming due to increase in shortwave absorp- tion from the lowering of albedo caused by afforestation reduces and can even overcome the cooling caused by the carbon drawdown. We use high reso- lution (0.05◦x 0.05◦), global, satellite-derived land cover, snow cover, albed o and shortwave flux data to investigate the effe...
