Energy balance of the intertidal zone of Western Hudson bay II: Ice‐dominated periods and seasonal patterns

Abstract

This study treats the energy balance during fast-ice and floating-ice conditions and examines overall seasonal patterns. The rate of ablation of the fast ice was controlled equally by net radiation and air temperature. The ratio of net/solar radiation increased 2.5 times during the ablation period owing to the decrease in ice albedo. Air temperature in the ablation zone was up to 8°C colder than that over the adjacent snow-free terrestrial surface and

Damming James Bay: I. Potential Impacts on Coastal Climate and the Water Balance

“…4. Onshore wind frequencies are greater for Churchill than for Moosonee (Rouse et al 1989). Because Churchill is an open coastal location similar to Ekwan, whereas Moosonee lies 20 km inland and is forested, the differences in frequencies between these stations were weighted 2:l toward the Churchill values in order to develop the long-term seasonal frequencies shown in where L is the latent heat of vaporization for water and p is the density of water.…”

Annual development of climatic summer in northern North America: accurate prediction of summer heat availability

“…Fig. 5B shows the occurrence of unusually high variability in the temperature at 05:OO h during the last half of June and until July 13, associated with shifting winds linked with the presence of sea ice (Rouse et al 1989, Weick & Rouse 1991. After the passing of spring there is usually an increase in the difference between temperatures at 05:OO h and those at mid-day, which did not occur at Churchill.…”

Energy balance of the intertidal zone of Western Hudson bay I: Ice‐free period

“…Factors influencing the energy budget include the different effects of onshore and offshore winds. Rouse and Bello (1985) working on the nearby spit have shown that air temperatures are substantially warmer for offshore than for onshore winds and that Q s and Q E are largest during offshore winds but Q H is largest when the winds blow onshore. Their work, however, did not examine the effect of the tidal cycle and relates more closely to the energy budget of the spit than that of the intertidal zone.…”
