Standard deviation maps for the — climatology are also provided in the Supplemental Material section for reference. Terrestrial variables reanalysis temperature and precipitation, as well as modeled discharge are spatially averaged over those sections of the HBW that make up the physical watershed. In addition, the interquartile range IQR of values within the region of interest HBC, HBW is presented for time series to account for spatial variability in each variable.
In order to quantify relative contributions from atmospheric and discharge conditions to freshwater—marine coupling in the HBC and HBW from to , spatially averaged values for each month and season are sorted, or ranked, in ascending order.
The equations used in the spatiotemporal analysis of atmospheric and river discharge variables are presented at the end of the Supplementary Material, for reference. Monthly plots and time series of SLP, surface winds, surface temperature, and precipitation and their standardized anomalies illustrate temporal variability and differences between years during the — time frame.
Anomalies are computed relative to — This period was selected since it 1 is postregulation and 2 coincides with an Environment and Climate Change Canada climatological and conventional normal time interval.
Postregulation in this case includes the development of run-of-the-river hydroelectric generation on the Albany and Moose Rivers; diversion of the Churchill River into the Nelson River; diversion of the Eastmain, Opinaca, and Caniapiscau Rivers to the La Grande River; and hydroelectric impoundment and regulation of the Nelson and La Grande Rivers. It includes only 1 year of the Rupert River diversion, which is fully in effect by — Noteworthy also is the negative anomaly located in the vicinity of the Port of Churchill in March associated with the SLP low and March blizzard.

Time series reinforce similarities and differences between years for the HBC relative to the — climatology; uncertainty is depicted by the IQR for all area-weighted spatially averaged variables to highlight spatial variability within the HBC Figures 5 — 8. Noteworthy are contrasting SLP high low regimes in October and in May as a signature of regional atmospheric circulation features.
Calm windy conditions are evident in October and August as a signature of local and highly variable atmospheric contributions within the HBC. Surface temperatures exhibit less variability, although standardized anomalies show that May and August of are characterized as warm cold months within the HBC. Precipitation standardized anomalies show that October and November May are characterized as wet dry months in , while August June are characterized as wet dry months in Spatial variability is in addition captured by confidence intervals in winds and precipitation, as is to be expected due to significant variability at local scales Supplemental Figures S2A—S2D and S4A—S4D.

Terrestrial precipitation from HydroGFD shows a basin-wide tendency toward increased precipitation in the March to October period Figure 9.

Precipitation presents a mixed record of anomalies in the observation period of — Reference period — outlined in solid, BaySys observation period — outlined in dashed. Overland temperature in the observation period shows a positive anomaly in the majority of months for and , with a warm summer and spring, cool autumn, and mixed winter Figure The spatial IQR of temperature is narrower relative to that of precipitation Figures 9 and Spatially averaged anomalies of temperature show being above or equal to the baseline period in all months except November, while presents a mixed anomaly record with a sustained cool autumn Figure As with the strongly seasonal and spatial temperature regime, standard deviations of temperature are greatest in summer, when temperature is greatest Supplemental Figure S6D.
Notably, greater anomalies of temperature in all months occur in the northern parts of the basin those with lowest mean temperature , reflecting the temperatures of higher latitudes increasing at greater speeds than their southern counterparts, producing increased variance in the reference period in the northern Foxe Basin region.
Discharge anomalies present a clearer, roughly decadal regime change Figure This presents itself in net discharge to the HBC as very dry in the s, very wet in the s, and somewhat dry in the s, including the observation period — Examining the annual and reference time series, we see that is a wet winter and then drier than the reference period, is wetter than reference in the winter and spring, followed by dry summer and autumn, and is average or drier than average in all months Figure Note that as the discharge is computed as a basin net discharge, there is no spatial IQR presented.
For the obvious reason of producing greater discharge, standard deviation of flow is greatest along the main river trunks Supplemental Figure S7D.

In , the absence of comparable variable extreme rankings between the HBC and HBW suggests processes are governed by local phenomena.
You can't price match these goods and you can't comparison shop them. You also can't get goods that are highly reviewed on the internet. If they like a brand the Bay goes full tilt with it. You like KitchenAid? You like Wusthof or Shun knives? Well let me show you every possible Zwilling J. Henckels knife ever made. The Bay just wants to sell you a kitchen full of matching goods.
If you order online, be aware that they are still using Canada post to ship some of their packages, no way to know until they ship. Everything i do want on my list can be had for cheaper and easier elsewhere. I also refuse to walk into a Bay as I seem to walk around in circles without actually ever finding anything. Finding your information. In February, just five years shy of its th anniversary, the Portage Avenue Bay store, the mammoth icon of a bygone era of downtown department store shopping, will shut down for good.
Hey there, time traveller! HBC's decision to close the ,square-foot store at Portage Avenue and Memorial Boulevard — twice the size of the Winnipeg Ikea store — won't come as a surprise to most people in the city. Over the years, the company has closed some of the store's six floors and its basement, consolidating stock on just two levels.
We also know that Winnipeggers have a strong and loyal affinity for the Hudson's Bay brand today, and we hope to continue that relationship for many years to come at our Polo Park and St. Vital locations, and through thebay. Company officials said it was a sad day, but as a result of changing consumer habits — shoppers long ago ditched the downtown for suburban malls and, more recently, online commerce — there was clearly no longer any commercial rationale for keeping the store open.
At one time, the closure of such a large store would cause serious ripple effects to commercial enterprises located within a few square kilometres. The reality is that the store has had little traffic for many years, its heft as a retail anchor long gone. As a child, my family used to drive downtown in our old Pontiac to look at the Christmas displays in the windows.
Friday was going to be a tough day for the store's 60 employees, some of whom have been there for many years. The discussion will move to what happens to the building. There have been several past attempts to put together viable renovation plans to repurpose the building, but all have fallen short. The Hudson Bay building on Portage Ave. Posted: PM Oct.
Why is the downtown Bay building significant? What's happened inside over the years?
