The qualities of arctic air are developed over ice and snow-covered ground. Arctic air is deeply cold, colder than polar air masses. Arctic air can be shallow in the summer, and rapidly modify as it moves equatorward. [8] Polar air masses develop over higher latitudes over the land or ocean, are very stable, and generally shallower than arctic air.
In the absence of such extreme air-mass changes, diurnal temperature variations typically range from 10 °F (5.6 °C) or smaller in humid, tropical areas, up to 40 to 50 °F (22.2 to 27.8 °C) in higher-elevation, arid to semi-arid areas, such as parts of the U.S. Western states' Intermountain Plateau areas, for example Elko, Nevada, Ashton ...
November gale, the Witch of November, or November Witch, refers to the strong winds that frequently blow across the Great Lakes in autumn. The "witches" are caused by intense low atmospheric pressure over the Great Lakes pulling cold Canadian/Arctic air from the north or northwest and warm Gulf air from the south.

Air pollution is the introduction of airborne chemicals, particulate matter or biological materials that cause harm or discomfort to organisms. [53] The population growth , industrialization and motorization of human societies have significantly increased the amount of airborne pollutants in the Earth's atmosphere, causing noticeable problems ...
A difference in air pressure causes an air displacement and generates the wind. The Coriolis force deflects the air movement to the right in the northern hemisphere and the left in the southern one, which makes the winds parallel to the isobars on an elevation in pressure card. [1] It is also referred as the geostrophic wind. [2]
November is the eleventh and penultimate month of the year in the Julian and Gregorian calendars. Its length is 30 days. November was the ninth month of the calendar of Romulus c. 750 BC. November retained its name (from the Latin novem meaning "nine") when January and February were added to the Roman calendar.
The aim of the Convention is that Parties shall endeavour to limit and, as far as possible, gradually reduce and prevent air pollution including long-range transboundary air pollution. Parties develop policies and strategies to combat the discharge of air pollutants through exchanges of information, consultation, research and monitoring.
