Abstract
Based on the meteorological data collected relative humidity from automatic and manual observation stations from 2005 to 2010 in Dalian.The regularity of average relative humidity comparison differential value of day,month and annual changes were analyzed.The results indicated that 90%daily average relative humidity of automatic weather station was higher than that of artificial observation station with average at 3.1%higher. The differences between automatic and manual observation data had obvious diurnal variation.Among the 24 times for timing,the maximum difference value in comparison was at 500-700,and the minimum was at 1300,and scheduled observation values were all positive.During the month of Jan.to Dec.,the maximum ratio was July to August and the minimum was April to May.The difference of minimum monthly relative humidity was less than 35%,and reverse phase with minimum monthly relative humidity.So long as average relative humidity had exceeded minimum monthly average relative humidity,the comparison differential value was growing with average relative humidity increased and the bias of that was comparatively larger under the condition of high relative humidity.关键词
