This document presents the climatological data measured at the US. Department of Energy's Hanford Site for calendar year 1996. Pacific Northwest National Laboratory(a) operates the Hanford Meteorology Station and the Hanford Meteorological Monitoring Network from which these data were collected. The information contained herein includes updated historical climatologies for temperature, precipitation, normal and extreme values of temperature and precipitation, and other miscellaneous

Further, the data are adjunct to and update , 1996 ; however, Appendix B-Wind Climatology (1994) is excluded. 1996 was cooler than normal, averaging 52.4"F, 0.9"F below'normal (53.3"F). For the 12-month period, 3 months were warmer than normal, and 9 were cooler than normal. 1996 was the second wettest year on record. Precipitation totaled 12.19 in., 195 % of normal (6.26 in.); snowfall totaled 57.5 in., the snowiest calendar year on record, compared to the normal of 13.8 in. The average wind speed during 1996 was 8.0 mph, 0.3 mph above normal (7.7 mph). The peak gusts during the year were 55 mph from the south-southwest on February 23 and from the southwest on April 23. There were 32 days with peak gusts 2 4 0 mph, compared to a yearly average of 26 mph. The heatingdegree days for 1995-1996 were 5,272 (1 % above the 5,231 normal). Cooling-degree days for 1996 were 1,014 (2% above the 994 normal). This document uses English units (e.g., miles per hour [mph], inches [in.], degrees Fahrenheit [OF]) when presenting all information. This decision to use English units was based on the fact that English units are still the standard in National Oceanic and Atmospheric Administration (specifically, the National Climatic Data Center and National Weather Service) reporting and publications. Throughout this document the term "normal" is used to indicate climatological normal, defined as an average value over a period of years of any meteorological element such as temperature, pressure, and rainfall. The accepted convention uses a 30-year time period, ending with the first year of each new decade (such as 1951-1980, 1961-1990, 1971-2000). The current time period used for climatological normals is 1961-1990. Some useful conversions between English units and metric equivalents are: 1 foot (ft) = 0.3048 meter (m) 1 mile (mi) = 1.609 kilometers (km) 1 inch (in.) = 2.54 centimeters (cm) 1 mile per hour (mph) = 0.447 metedsecond ( d s )
