• <br />3.0 RESULTS AND DISCUSSION <br />3.1 1979 Climatic Patters at the Mt. Gunnison Hine <br />3.1.1 Precipitation and Soil Hoisture <br />f The winter, spring, and early su,nmer of 1979 were characterized by <br />abundant precipitation which enhanced growing conditions. Very dry <br />conditions prevailed from mid-summer to late fall. During the late <br />i fall, precipitation increased slightly. Precipitation data collected <br />from just east of the Bear Hine were analyzed for precipitation amount <br />and frequency. These data are presented in Appendix A. <br />Over-winter precipitation (1 December 1978 to 28 February 1979) <br />amounted to 6.19 inches. Spring sad early summer (1 Hareh 1979 to <br />22 June) precipitation amounted to 6.46 inches as compared to <br />3.93 inches for this same time period in 1978. Ia terms of the spring <br />and early summer, precipitation amounts equaled or exceeded 0.20 inches <br />on 12 days: Hareh 21, Hareh 27, Hareh 28, April 9, April 10, Haq 7, <br />Hay 8, Hay 29, June 6, Juae 7, June 8, June 18. During this same time <br />period in 1978, precipitation equaled or exceeded 0.20 oa only 8 days. <br />•`, Precipitation equaled or exceeded O.iO inches (but was less than <br />J 0.20 inches) on 8 days during 1979. These dates were: Hareh 2, <br />Hareh 16, Hareh 18, Hareh 29, Hareh 31, April 11, Hay 10, May 30. There <br />were several long periods during which ao, measurable rainfall was <br />recorded: March 3- Hareh 15 (13 days), April 1-April 13 (13 days), <br />April 13-April 27 (13 days) and Hay 12-Hay 23 (12 days). <br />Precipitation from June 23 through October 31 amounted to <br />2.82 inches in 1979. In 1978 during this same time period, 2.19 inches <br />were recorded. Summer precipitation for 1979 equaled or exceeded <br />0.20 inches on 3 days: June 30, July 6, and October 20. Three days <br />equaled or exceeded 0.20 inches precipitation in 1978. Precipitation <br />between 0.10 sad 0.19 occurred on 4 days in 1979: August 15, August 16, <br />- August 3D and October 21. Two droughty periods occurred in 1979 between <br />September 6 and September 19 (14 days) and between September 27 and <br />_ October 12 (16 days). These conditions indicate that during the warmest <br />part of the year, plant seedlings suffered varying amounts of drought <br />stress though summer-fall droughts were not as rigorous as is 1978. <br />C„ <br />12 <br />
