NC State Climate Office Releases Second Blog

maxSLP-19810213Last month, the North Carolina Climate Office began a year-long project on recounting the state’s most significant weather events. Corey Davis, Applied Climatologist for the State of North Carolina talks about the project:

“The idea for this came together last year when we started to think about in recent years some of the hurricanes we have had, the warm spells and drought as well as the snow storms. So we wanted to talk about some of the extremes we have seen.”

Davis talks about this month’s blog posting, out earlier this week:

“This month we look at North Carolina’s high pressure records. They are also caused by these big winter time arctic air masses that come in. Up at the North Pole they don’t get a lot of sunlight during the winter so these air pressure systems build up and get colder and colder. Because cold air is very dense they get higher pressure building up. Occasionally the jet stream will push them south and rarely they will reach us here in NC.”

And the record high pressure reading was:

“The highest pressure that we found was 1050 millilbars in Greensboro. To give some perspective, on a typical day, pressure is around 1000 millibars, or 30” of mercury on the barometer. So 50 additional is a very high pressure air mass.”

Which is the opposite of a cyclone explains Davis:

“We call the anti-cylones. They usually develop over Canada and when they pus to the south we see the cold air roll in along with this high pressure.”
