Using MP-3000 A microwave radiometer data of Dongying City,the precipitation and heavy fog during the period from August 2011 to July 2014 in Dongying City were analyzed.The results showed that the characteristics at 1 hour before precipitation in torrential rain and heavy rain showed double-peak structure and step increment in proportion to the magnitude,while in moderate rain and light rain didn′t show this structure.Before the fog,the thickness of the temperature inversion layer was about 400 meters,and the temperature difference of the temperature inversion layer was small at the beginning.The thickness of the water vapor density was 200 to 500 meters when 1 hour before the fog occurs.The height of the increment layer was near the top of the temperature inversion layer and higher than the initial temperature inversion layer,which verified that the temperature inversion layer was growing during the process of fog.
