Isztar Zawadzki
Isztar Zawadzki (February 9, 1939 - February 11, 2023) was a Canadian meteorologist, born in Poland and raised in Argentina. Professor at the McGill Atmospheric and Oceanic Sciences department in Montreal, Québec, he specialized in radar meteorology, a field where he has made important contributions. Biography Zawadzki was born in Warsaw, Poland on February 9, 1939, just before the outbreak of World War II. Fleeing anti-Semitism and war, his mother took refuge with him in the USSR, then in Argentina. It was in this country that he received a degree in physics from the University of Buenos Aires in 1963. He then specialized in radar meteorology by completing a master's degree (M.Sc. 1968) and a doctorate (PhD. 1972) at McGill University in Montreal. After his studies, he was first a professor at the Université du Québec à Montréal (UQÀM) during the 1970s where he became director of studies in atmospheric sciences from 1971 to 1982, then director of the physics department. fro ...

McGill Atmospheric And Oceanic Sciences
The Department of Atmospheric and Oceanic Sciences of McGill University is the largest university atmospheric-oceanic sciences group in Canada. In 2012, it has 11 Faculty and 6 Associate Faculty members, 5 support staff, 14 research associates and postdoctoral fellows, and 31 graduate students. It is known worldwide, in particular for weather radar research and Arctic studies. It has operated the second oldest weather observatory in Canada since 1862. History Since 1840, Charles Smallwood, a medical doctor and avid amateur meteorologist, was taking daily weather reports at his house in the village of Saint-Martin on Île Jésus (now Laval a suburb of Montreal). He was named "honorary professor" in Meteorology at McGill University in 1856, and at his suggestion, the first McGill Weather Observatory was established in 1862. The first instruments were donated by Smallwood et he was the first director of the Observatory. Since then, there is regular measurement of meteorological var ...

Cloud Physics
Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. These aerosols are found in the troposphere, stratosphere, and mesosphere, which collectively make up the greatest part of the homosphere. Clouds consist of microscopic droplets of liquid water (warm clouds), tiny crystals of ice (cold clouds), or both (mixed phase clouds), along with microscopic particles of dust, smoke, or other matter, known as condensation nuclei. Cloud droplets initially form by the condensation of water vapor onto condensation nuclei when the supersaturation of air exceeds a critical value according to Köhler theory. Cloud condensation nuclei are necessary for cloud droplets formation because of the Kelvin effect, which describes the change in saturation vapor pressure due to a curved surface. At small radii, the amount of supersaturation needed for condensation to occur is so large, that it does not happen naturally. Raoult' ...

Argentine Meteorologists
Argentines, Argentinians or Argentineans are people from Argentina. This connection may be residential, legal, historical, or cultural. For most Argentines, several (or all) of these connections exist and are collectively the source of their being Argentine. Argentina is a multiethnic society, home to people of various ethnic, racial, religious, denomination, and national origins, with the majority of the population made up of Old World immigrants and their descendants. As a result, Argentines do not equate their nationality with ethnicity, but with citizenship and allegiance to Argentina. Aside from the indigenous population, nearly all Argentines or their ancestors immigrated within the past five centuries. Among countries in the world that have received the most immigrants in modern history, Argentina, with 6.6 million, ranks second to the United States (27 million), and ahead of other immigrant destinations such as Canada, Brazil and Australia.

Canadian Meteorologists
Canadians () are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity and Canadian values. Canada has also been strongly influenced by its linguistic, geographic, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
