| Abstract: | Based on the observational data from 16 meteorological stations in Hebei Province during 1965-2006,temporal and spatial feature,day variational law and inter-decadal variations of dense fog and strong fog were detailedly analyzed by using EOF and Mann-Kendall methods.Results showed that annual days of dense fog and strong fog are 5d and 1d respectively,their days in plain are more,The season of multi-dense fog and multi-strong fog are in autumn and winter,their frequency in december is the highest.The starting time of dense fog and strong fog occuring is from 20:00 to 7:00 of the next day.The ending time is from 8:00 to 12:00.3-6h of the dense fog and strong fog are the most.Inter-decadal variations for them showed upward trend. |
