The kitchen boasts a huge pantry, stocked with a six month supply of staple goods such as canned goods, dry goods, and frozen foods. Fresh produce, milk, and bread are brought up weekly on shift changes. Unfortunately, we have not yet found a pizza parlor which will deliver to the top of the mountain. Rime ice is essentially frozen fog. When the droplets freeze, they can form delicate, feather-like structures which grow into the wind at a rate of up to a foot an hour, coating everything in white.
Wind speed is measured using either of two instruments.
When winds are light, a three-cup anemometer records the velocity, as it is especially sensitive. Wind speed is measured by the rate at which the cups turn. However, stronger winds, over 30 miles per hour, tend to put a lot of wear and tear onto such an instrument, and cause its bearings to wear out prematurely. Using a customized application for a piece of aviation hardware, the Observatory's pitot vanes into the wind and measures its speed essentially through the pressure exerted through a hole in the front of the instrument. The reading is then recorded on a wind chart in the Observatory's weather room, and is also converted to an electronic signal for other purposes.
