Kennedy Lake on Vancouver Island saw over 318 mm (12.5 in) of rainfall. [17] The South Coast region of British Columbia saw higher rainfall amounts than those seen during the record breaking floods in 2021. The trajectory of the moisture plume limited the impact of the Olympic Mountain rain shadow in parts of British Columbia. At the same time ...
The heavy rain washed sediment into the city's reservoirs, and, as result, many businesses were advised to stop serving beverages prepared from tap water due to water contamination. At Vancouver International Airport, 28 cm (11 in) of snow was recorded from the night of November 25 to the morning of November 27.
The Toronto observatory ended in 1853, but the colonial government of the province of Canada took over the service and continued collecting climate data. On May 1, 1871, the new Dominion of Canada established the Meteorological Service of Canada by providing a $5000 grant to Professor G. T. Kingston of the University of Toronto to establish a ...
The following tables show the average maximum and minimum temperatures of Canada of various cities across Canada, based on the climate period from 1981 to 2010 for the months of January and July (generally the lowest and highest average temperature months, but not in every case).
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. [1] On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, [2] [3] just below the stratosphere.
Microsoft's Aurora system offers global 10-day weather and 5-day air pollution (CO 2, NO, NO 2, SO 2, O 3, and particulates) forecasts with claimed accuracy similar to physics-based models, but at orders-of-magnitude lower cost. Aurora was trained on more than a million hours of data from six weather/climate models. [83] [84]
Environment and Climate Change Canada (ECCC)'s Climate Research Division summarized annual precipitation changes, evaluating records up to 2007. They observed: "Precipitation has generally increased over Canada since 1950 with the majority of stations with significant trends showing increases.
The quantitative precipitation forecast (abbreviated QPF) is the expected amount of melted precipitation accumulated over a specified time period over a specified area. [1] A QPF will be created when precipitation amounts reaching a minimum threshold are expected during the forecast's valid period.
