Dorval, Quebec
Dorval (; ) is an on-island suburban city on the island of Montreal in southwestern Quebec, Canada. In 2016, the Canadian Census indicated that the population increased by 4.2% to 18,980. Although the city has the largest surface area in Montréal’s west side, it is among the least densely populated. Montréal–Pierre Elliott Trudeau International Airport constitutes about 60% of the city's land; consequently, all of Dorval's population is concentrated in the southern part of the city. Dorval is the oldest city in the west side of Montréal, having been founded in 1667, and one of the oldest in Canada and North America. History The history of Dorval dates back more than 350 years to 1665 when Sulpician priests established a mission on the outskirts of Ville-Marie, a French settlement which later became known as Montreal. Dorval was originally named Gentilly. It was later renamed La Présentation-de-la-Vierge-Marie. In 1691, the domain of La Présentation, originally own ...

Meteorological Service Of Canada
The Meteorological Service of Canada (MSC; ) is a branch of Environment and Climate Change Canada, which primarily provides public meteorological information and weather forecasts and warnings of severe weather and other environmental hazards. MSC also monitors and conducts research on the climate, atmospheric science, air quality, water quantities, ice and other environmental issues. MSC operates a network of radio stations throughout Canada transmitting weather and environmental information 24 hours a day called Weatheradio Canada. History Private Observations Prior to 1840, meteorological observations in Canada were made by private individuals, other entities (like HBC), and explorers, but this information was not provided to the general public. Her Majesty's Magnetic and Meteorological Observatory In 1840, British officials ( British Ordnance Department) and the Royal Society established an observatory in Toronto, Canada West, one of a few across the British Empire and ...

Numerical Weather Prediction
Numerical weather prediction (NWP) uses mathematical models of the atmosphere and oceans to weather forecasting, predict the weather based on current weather conditions. Though first attempted in the 1920s, it was not until the advent of computer simulation in the 1950s that numerical weather predictions produced realistic results. A number of global and regional forecast models are run in different countries worldwide, using current weather observations relayed from radiosondes, weather satellites and other observing systems as inputs. Mathematical models based on the same physical principles can be used to generate either short-term weather forecasts or longer-term climate predictions; the latter are widely applied for understanding and projecting climate change. The improvements made to regional models have allowed significant improvements in Tropical cyclone track forecasting, tropical cyclone track and air quality forecasts; however, atmospheric models perform poorly at han ...

Global Environmental Multiscale Model
The Global Environmental Multiscale Model (GEM), often known as the CMC model in North America, is an integrated forecasting and data assimilation system developed in the Recherche en Prévision Numérique (RPN), Meteorological Research Branch (MRB), and the Canadian Meteorological Centre (CMC). Along with the NWS's Global Forecast System (GFS), which runs out to 16 days, the ECMWF's Integrated Forecast System (IFS), which runs out 10 days, the US Naval Research Laboratory Navy Global Environmental Model (NAVGEM), which runs out eight days, the UK Met Office's Unified Model, which runs out to seven days, and Deutscher Wetterdienst's ICON (ICOsahedral Nonhydrostatic), which runs out to 7.5 days, it is one of the global medium-range models in general use. Operation Deterministic model The GEM's operational model, known as the Global Deterministic Prediction System (GDPS), is currently operational for the global data assimilation cycle and medium-range forecasting, the regiona ...

Mesoscale Meteorology
Mesoscale meteorology is the study of weather systems and processes at horizontal scales of approximately to several hundred kilometres. It is smaller than synoptic scale meteorology, synoptic-scale systems (1,000 km or larger) but larger than Microscale meteorology, microscale (less than 1 km). At the small end, it includes storm-scale phenomena (the size of an individual thunderstorm). Examples of mesoscale weather systems are sea breezes, squall lines, and mesoscale convective complexes. Vertical velocity often equals or exceeds horizontal velocities in mesoscale meteorological systems due to nonhydrostatic processes such as buoyant acceleration of a rising thermal or acceleration through a narrow mountain pass. Classification The History of weather forecasting, earliest networks of weather observations in the late 1800s and early 1900s could detect the movement and evolution of larger, synoptic scale, synoptic-scale systems like high pressure area, high and low-pressure area ...

Ensemble Forecasting
Ensemble forecasting is a method used in or within numerical weather prediction. Instead of making a single forecast of the most likely weather, a set (or ensemble) of forecasts is produced. This set of forecasts aims to give an indication of the range of possible future states of the atmosphere. Ensemble forecasting is a form of Monte Carlo analysis. The multiple simulations are conducted to account for the two usual sources of uncertainty in forecast models: (1) the errors introduced by the use of imperfect initial conditions, amplified by the chaotic nature of the equations of the atmosphere, which is often referred to as sensitive dependence on initial conditions; and (2) errors introduced because of imperfections in the model formulation, such as the approximate mathematical methods to solve the equations. Ideally, the verified future atmospheric state should fall within the predicted ensemble spread, and the amount of spread should be related to the uncertainty (error) ...

Supercomputer
A supercomputer is a type of computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2022, supercomputers have existed which can perform over 1018 FLOPS, so called Exascale computing, exascale supercomputers. For comparison, a desktop computer has performance in the range of hundreds of gigaFLOPS (1011) to tens of teraFLOPS (1013). Since November 2017, all of the TOP500, world's fastest 500 supercomputers run on Linux-based operating systems. Additional research is being conducted in the United States, the European Union, Taiwan, Japan, and China to build faster, more powerful and technologically superior exascale supercomputers. Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in various fields, ...

André Robert
Dr. André Robert (April 28, 1929 – November 18, 1993) was a Canadian meteorologist who pioneered the modelling the Earth's atmospheric circulation. Biography and career Born in New York, NY in 1928, Robert moved to Grand-Mère, Quebec, in May 1937. He received his BSc from Laval University in 1952 and his MSc from the University of Toronto in 1953. He began employment with the Meteorological Service of Canada as a weather forecaster, then in 1959 shifted his interest to research in atmospheric models for short and medium-range numerical weather prediction. For his PhD (awarded in 1965), Robert worked at McGill University on the spectral model using spectral harmonics for the representation of atmospheric fields in global climate and numerical weather prediction models. Between 1963 and 1970, Robert developed the semi-implicit time integration algorithm for an efficient integration of the primitive equations for numerical weather prediction and climate models.
