Clad in fleece and ski goggles, Mike Dorfman stepped out onto the observation deck at the summit of the Northeast’s tallest mountain Monday in the name of science — and a little bit of fun.

Dorfman is a weather observer on Mount Washington, where sustained winds blew at 91 mph and gusts peaked at 110 mph on Monday.

“It’s really impossible to imagine the winds on the summit without experiencing them firsthand,” Dorfman wrote in a blog post about the video.

He says the building they work out of at the summit of Mount Washington has concrete walls that are three feet thick and windows made of bullet-resistant glass. “Even with this protection, the constant, dull roar of the wind is ever-present in the Observatory’s Weather Room.”

The observers have to record the weather on the summit every hour, so when the temperature is below freezing, they need to thaw the instruments.

“Heading up to the tower to deice every hour is an adventure,” says Dorfman. “The enclosed parapet-like tower roars like the sound of a jet engine as a plane is taking off, and exiting the top door of the parapet is like opening up the window of that ascending jet.”

When they have to decide what kind of precipitation is falling, they get back to basics. Technology is no match for 100 mph wind.

“Discerning whether there is snowfall or blowing snow (or both) is one of our hourly tasks, and the easiest way to do this is to take a felt-covered board and hold it in the wind,” Dorfman wrote. “This makes it easy to determine what form of ice is flying through the air (the ice that you can so easily feel through many layers of clothing).”

Makes us happy we only have to deal with a little bit of rain today.
