Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.
Pressure and the Polar Vortex
It’s baaack. It has been 4 years since a polar vortex disruption brought artic weather to the Northern Hemisphere. In the 2014-2015 winter, it meant historically cold temperatures and high snowfall in many areas.
While a polar vortex (a large area of low pressure and cold air that surrounds both of the Earth’s poles) always exits, other weather conditions can disrupt it and cause its effect to spread. Normally, the counter-clockwise (vortex) airflow keeps the colder air near the pole. The disruption is detected by pressure measurements in the stratosphere – not a ground level. While, a variety of pressure levels are used to mark its position, the 50 mb pressure surface is most often used to identify its location.
