2. Low-pressure area - Wikipedia

   en.wikipedia.org/wiki/Low-pressure_area

   In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area . Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), [ 1 ] while high-pressure areas are ...

3. Pressure system - Wikipedia

   en.wikipedia.org/wiki/Pressure_system

   A low-pressure area is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere. [1] The formation process of a low-pressure area is known as cyclogenesis. [2]

4. Centers of action - Wikipedia

   en.wikipedia.org/wiki/Centers_of_action

   The French meteorologist Léon Teisserenc de Bort was the first in 1881 to apply this term to maxima and minima of pressure on daily charts. The main centers of action in the Northern Hemisphere are the Icelandic Low, the Aleutian Low, the Azores/Bermuda High, the Pacific High, the Siberian High (in winter), and the Asiatic Low (in summer).

   A low air pressure: 15 February 1941 in Évora at 931 hPa is reported by one source, which also reports a minimum value of 937 hPa in Coimbra and 950 hPa in Lisbon during the passage of this low pressure. [291] The Instituto Português do Mar e da Atmosfera give a value of 938.5 hPa at station level for Coimbra (not MSLP). [292]

6. Thermal low - Wikipedia

   en.wikipedia.org/wiki/Thermal_low

   That, combined with the rise of the hot air, results in a low pressure area called a thermal low. [1] Over elevated surfaces, heating of the ground exceeds the heating of the surrounding air at the same altitude above sea level, which creates an associated heat low over the terrain, and enhances any thermal lows which would have otherwise existed.

7. Colorado low - Wikipedia

   en.wikipedia.org/wiki/Colorado_low

   A Colorado low is a low-pressure area that forms in southeastern Colorado or northeastern New Mexico, typically in the winter. After forming, the system moves across the Great Plains . [ 1 ] Colorado lows can produce heavy wintry precipitation , and have a general east to northeast movement, impacting regions as far north as Winnipeg and as far ...

8. Alberta clipper - Wikipedia

   en.wikipedia.org/wiki/Alberta_clipper

   Average trajectory of a clipper. An Alberta clipper, also known as an Alberta low, Alberta cyclone, Alberta lee cyclone, Canadian clipper, or simply clipper, is a fast-moving low-pressure system that originates in or near the Canadian province of Alberta just east of the Rocky Mountains and tracks east-southeastward across southern Canada and the northern United States to the North Atlantic Ocean.
