What is a high-pressure area?
A high-pressure area is a region with higher atmospheric pressure than the surrounding regions. Scientists call these features anticyclones or simply highs.
Questions about High-pressure area
Short answers, pulled from the story.
How do high-pressure areas form?
High-pressure areas form due to downward motion through the troposphere where air becomes cool enough to precipitate its water vapor. Large masses of drier air descend from above creating distinct types of systems depending on their origin and thermal properties.
Which way does wind flow in a Northern Hemisphere high-pressure system?
In the Northern Hemisphere high-pressure systems rotate clockwise because the Coriolis effect bends wind direction opposite to Earth's rotation. Air flows from the center outward while friction with land slows down the wind causing it to flow more outward than without friction.
Where are the horse latitudes located?
The horse latitudes or torrid zone sit roughly at the 30th parallel as source of warm high pressure systems. Hot air closer to the equator rises then cools losing moisture before transport poleward where it descends creating the high-pressure area.
When was the highest barometric pressure ever recorded on Earth?
The highest barometric pressure ever recorded on Earth measured 1085.7 hPa in Tosontsengel Zavkhan Mongolia on the 19th of December 2001.
