A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation .
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]
The South Pacific High is a semi-permanent subtropical anticyclone located in the southeast Pacific Ocean. The area of high atmospheric pressure and the presence of the Humboldt Current in the underlying ocean make the west coast of Peru and northern Chile extremely arid.
When surface winds become light, the subsidence produced directly under a high-pressure system can lead to a buildup of particulates in urban areas under the high pressure, leading to widespread haze. [11] If the surface level relative humidity rises towards 100 percent overnight, fog can form. [12]
The North Pacific High is a semi-permanent, subtropical anticyclone located in the northeastern portion of the Pacific Ocean, located northeast of Hawaii and west of California. It is part of the great belt of anticyclones known as the subtropical ridge .
Forecasters looking ahead to the conditions say that the pattern is favoring generally dry conditions for Sunday, Jan. 28, in the Santa Clara area. "High pressure in place will help to hold off ...
Ridge line extending to the left of the high pressure center (H). In meteorology a ridge or barometric ridge is an elongated area of relatively high atmospheric pressure compared to the surrounding environment, without being a closed circulation. [1] It is associated with an area of maximum anticyclonic curvature of wind flow.
High-end homes — median values in the ZIP code were over $3.4 million last year, according to data provided by Zillow — are nestled into an ecosystem with fire-prone chaparral plants like ...
