      First Alert Chief Meteorologist Wayne Mahar goes to the top of the Dome after record wind

      Readout of the Carrier Dome wind gust

      After record breaking wind gusts Tuesday night, First Alert Chief Meteorologist Wayne Mahar went to the top of the Carrier Dome to investigate.

      At about 10:40pm Tuesday, gusts of 105 miles per hour were recorded at the top of the Dome. That's the highest wind speed ever recorded there. The previous record was 78 miles per hour.

      Chief Meteorologist Wayne Mahar attributes the record gust to an increase in wind speed from the Bernoulli Effect. Indications are the true "ground" wind speed was 75-80 mph, but was enhanced by this Bernoulli Effect which, in effect, compresses the wind and speeds up the flow of air, thus the 105 mph gust.

      It is also important to note that it is not just simply the speed of the wind, but when you get hit with this type of wind, it increases the air pressure above the Dome and decreases the air pressure below. The effect here, as Pete Sala told Wayne, is that the roof of the Dome was trying to literally "lift up and off." Dome Management had to increase air pressure inside the Dome to equalize and stabilize the roof.

      Climbing to the top of the Dome is an interesting experience. At times, climbers have to use a rope to pull themselves forward. Once on top, you mostly walk on the frame of the Dome. However, it is possible to walk right on the roof, being held up only by the air pressure from underneath.

      Take a look at the picture posted along with this story. That's Wayne Mahar and Chris McGrath at the top of the Carrier Dome!
