文摘Through analyzing the situation of atmospheric circulation and the variation of meteorological element at the time of dense fog happened on November 10,2005 in Jining,the results indicated that there were abundant water vapor,weaker pressure field and wind field,weaker cold air in high altitude,stable stratification in underlying bed and ground was located in the bottom of cold high pressure,all those conditions were beneficial to the generation of dense fog in Jining.
文摘Through analyzing influence system,trigger mechanism,stability and helicity of the cloudburst on Jul.2nd to 3rd in 2006 in Shandong Province,it is showed that the cloudburst is produced by shear line in 850 hPa and ground Huanghuai cyclone.Convergence lifting movement in shear line and north of cyclone trigger release of unstable energy,and southwest wind jet stream in low altitude provide sufficient water vapor and unstable energy.
