Specifically, the ratio of the total surcharge for the 2010-2011 winter simulation to the corresponding ASCE 7 value is presented for each of the eight LCD stations with upwind fetch distances ranging from 50 to 500 feet. The ground remains a constant temperature 10 feet below the earth's surface, regardless of how cold the air outside is, and that heat is distributed throughout your home. Predictions given by the statistical basis for determining ground snow loads are bounded by an upper and lower limit. Keep lamps, light fixtures and light bulbs away from anything that can burn.
