- Abstract:
- Based on daily precipitation data of the 28 weather stations in Heilongjiang Province during the period from 1959 to 2010,the climatic characters and changing trend of rainfall days,rainfall amount and rainfall intensity in Heilongjiang Province were analyzed by using the methods of climate trending rate and Inverse Distance Weighted interpolation method.The results showed that the annual precipitation slightly decreased and the decrease of rainfall dominantly resulted from the decline in trace and light rainfall in summer.Rainfall intensity showed a significant decrease trend,what’s more,the decrease of intensity was mainly dued to the decline of trace and light intensity.The number of annual and seasonal (except summer) rainfall days increased while the increase of rainfall days owed to the significant going up in trace,light and moderate rainfall days.Spatial distribution characteristics of the precipitation indicated that precipitation of the central area was the highest,followed by the southern area,while precipitation of the west and north was relatively less.
