Show - 5- It is felt that this took place for two reasons; both can be corrected and are installation problems: 1. During the latter part of February, the 775- B was moved to a more central location within the fenced diameter. 2. The 6* ground to snowfence gap was reduced by snow accumula-tion. ( See photo taken on April 10, 1962, Maximum Accumula-tion Stake Reading.) In any event, with further inexpensive modification, it is felt that an acceptable method of recording snowfall can be man- made by the use of this type of installation. This is called the man- made nominal wind action área. Figure 1 Shows general overall installation of the snow fence to make a man- made nominal wind action área. Note the difference in snow depth under the fence at the right of the photo and at the left of the photo. The left side of the photo is northerly and the edge of the installation is on the edge of the fill which drops off for about 10 ft. The northern high speed winds come up the fill bank and under the fence causing much scouring. Figure 2 Location of the Tipping Bucket, the Friez 775- B and the 8" can. Ali of this instrumentation is on a large table. Figure 3 New snow stakes and settlement gauge. |
