The Global Precipitation Mesaurement (GPM) satellite provides the next generation of global satellite precipitation products.We selected the super typhoon "Maria" (201808),which occurred in July 2018,for study in this paper.We analyzed the precipitation rate,the type of precipitation and height of the rain top,variation of the vertical profile of the precipitation rate,and distribution characteristics of the three-dimensional structure of the precipitation rate at two different times.The following main conclusions are drawn:At both times,Maria was in the super typhoon stage,and the eye area of the typhoon was a deep convection area at time A,while at time B the convection in the eye area was weakened,yet a strong spiral rain belt was present.The maximum precipitation rate did not correspond to the height of the storm top at both times A and B,nor did it correspond to the microphysical processes in the precipitation cloud system.The high value region of water particle content detected by a low frequency GMI of 18.7 GHz corresponds closely to the heavy precipitation rate.In addition,the signal of ice particles detected at a high frequency of 183.31±3 GHz was consistent with the distribution of the height of the storm top.The vertical profiles corresponding to different precipitation rates showed that the precipitation rate changed sharply at a 5 km altitude,which was due to either the collision and growth of raindrops or the decrease of evaporation at this altitude.From time A to time B,the radius of cloud wall greater than 10 mm·h^-1 decreased significantly.There were weak precipitation areas present,and no precipitation areas were observed between the eye wall and spiral rain belt at time B.
