Based on the surface meteorological data from 194 weather stations located in the Northeast of China during 1961~2013, temporal and spatial characteristics of haze days and haze with varied intensity have been analyzed. In terms of spatial distribution, there are two high-value centers located in the central Liaoning Province and north central Heilongjiang Province respectively, where annual total haze events generally exceed 50days. The least haze events occur in the west of Jilin Province with less than 2days per year.Furthermore, the spatial distribution of varied intensity (slight, mild, moderate and severe) haze days is approximately consistent with that of the total haze days.Haze events are more frequently observed in winter (57.9%), followed by autumn and they are least frequently in springs. Average number of annual haze days in study area has a significant increasing trend of 2.9d/decade during 1961~2013 with greatest increase occurring during 1980~2000. Days with slight ,mild, moderate and severe haze have also increased, but mild, moderate and severe haze days reduced slightly in the 21st century compared with the 1980s.
