The characteristics of typhoon Matmo (1410) are analyzed before and after its landfall on Taiwan and Fujian based on the analysis data from NCEP/NCAR (National Centers for Environmental Prediction/National Center for Atmospheric Research) Global Forecast System (GFS), the reanalysis data from ECMWF ERA-Interim and rainfall observations derived from station observations and satellite retrievals of precipitation from 18 to 26 July 2014. The results indicate that the trajectory of Matmo was mostly influenced by the steering flow of subtropical high. The deep vortex structure of Matmo still maintained around the time of its landing at Fujian, cooperating well with the vertical circulation formed by the ascending motion over southeastern Fujian and the descending motion near Taiwan Strait and western Fujian. Besides, the water vapor originated from the Bay of Bengal and South China Sea were continuously transported into Matmo by the southwesterly jet (wind speed greater than 16 m s^-1 at 850 hPa), which provided the necessary energy required for maintaining the typhoon circulation around landing time. The southwesterly jet transported energy and momentum from the South China Sea to the coastal region of southeastern China. Meanwhile, sufficient water vapor transport and convergence of moisture at the low levels were conductive to the occurrence and maintenance of heavy rain caused by Matmo. The result also shows that the weak vertical wind shear, which was favorable for the maintenance of warm core structure and divergence at upper levels, was another reason for the slow weakening of Matmo after its landfall.
