Precipitation Difference and Relativity between Automatic and Conventional Observation over Urumqi Region
摘要
Abstract
Based on rainfall data observed automatically and manually in Urumqi during the 2004-2008,this article analyzed the observation difference and its reason,and discussed the correlation between the two ways.The results showed that 64.7% rainfall data observed automatically were higher than that by manual observation;and the difference ranged from-3.2 to 1mm with an average of-0.29 mm;the frequency distribution of difference value showed the partial normal distribution with steeper distribution curve,and the differences were rather concentrated;the coarse difference rate and consistent rate of comparison data were 5.88% and 90.1% respectively,and rainfall percentage error within ± 4% was 89% in all data,the error percentage of observation data reached 11.0%;the correlation coefficient of the two observation data was 0.999 with obvious linear correlation.The difference value of observational data was generated by combined effects of various factors.关键词
