ATTACHMENT 11. PLANT HATCH 1991 METEOROLOGICAL
SUMMARY
The overall meteorological data collection at Plant Hatch was very good during 1991. Most of the data was collected using the site DRDT computer. The computer functioned well throughout the year with the exception of a few problems in December. Data collection was available - f rom the computer about 97% of the time during 1991. During the periods when the computer was down, data were digitized f rom strip charts. There were a few problems with instrumentation that lasted for extended periods of time. The wind speed and direction at 60m were out-of-service for much of Mr.rch. Also, the wind direction at 100m was not functioning properly during part of April and May. The most serious problem was with i the two delta temperatures on the primary tower (60-10m and 100-10m) that intermittently gave incorre-t low readings. During these time periods, data were substituted f rom the backup tower and adjusted to the delt6 temperature height. The problem was fixed in early November. The table below summarizes the data collection over the psst five years. Since the computer was installed at the end of 1989, the data collection has improved. The 1991 data recovery for pertinent parameters was the s highest ever achieved at better than 99%. 1987 1988 1989 1990 1991 5-Yr Wind Speed 10m 96.3 98.5 96.7 98.6 99.3 97.9 Wind Speed 60m 93.7 93.4 83.9 98.6 89.8 91.9 i Wind Speed 100m 94.3 98.0 92.8 95.2 99.6 96.0 Wind Direction 10m 96.5 99.3 98.4 98.7 99.4 98.5 Wind Direction 60m 94.4 93.9 83.8 97.0 95.C 93.0 Wind Direction 100m 97.4 98.2 97.6 78.4 94.4 93.2 ' Delta Temperature 60-10m 97.3 98.9 93.2 98.2 99.4 97.4 Delta Temperature 100-10m 97.4 96.3 92.2 98.3 99.3 96.7 Temperature 10m 95.0 99.4 98.2 96.4 99.3 97.7 Dew Point 10m 95.0 99.4 91.2 98.6 99.5 96.7 Precipitation 95.0 94.2 91.6 98.7 99.4 95.8 Composite WS, WD 10m, DT 60-10 93.2 97.2 90.0 98.2 99.2 95.6 WS, WD 60m, DT 60-10 90.1 91.3 77.8 96.6 89.2. 89.0 a WS, WD 100m, DT 100-10 91.8 93.6 85.6 73.1 94.4 87.7 i J 7419A021492 i
The ambient and dew point temperature plots in Attachment 9 show that temperatures were generally cooler than in recent years, particularly, during the summer months. The cooler temperatures were probably causeo by the increase in precipitation over the year, causing more cloudy dajs than normal. The affect on the dew point temperature is not as great since dew point readings are higher during periods of rain or snow. The wind roses in Attachments 4 through 7 show very good agreement between levels on the tower and also with the backup tower. In all cases, the peak wind direction was f rom the northeast. Secondary peaks of much less magnitude were generally from the west or southwest. The northeast peaks occurs in all seasons and at every level on the towers. The secondary peaks tend to vary somewhat with more south to southwest winds. occurring in the summer season. These wind conditions are consistent with data from previous years. The joint frequency tables of wind _ speed and direction versus delta temperature are shown in Attachments 1, 2 and 3. The table below summarizes the last five years of operation' of the 100m tower. The table uses the wind speed and airection from the 10m level versus the delta temperature between 60 and 10 meters. The 1991 data shows-less stable hours than in any of the last five years and a continuation of the trend towards unstable conditions in comparison to the early years of operation of the 100m tower. The biggest change was in the neutral "0" stability, where the higher percentage can be attributed +o the increase in rain, resulting in more neutral conditions.

The total for the year was 57.62 inches which was above ava age for the plant area. The amount of rain per month varied widely. with most of the rain falling in the first eight months of the year. The l 57 inches of rain represents the most rainf all since the 100m tower went into operation eight years ago. 7419A021492
