| 摘 要： | With PSU/NCAR nonhydrostatic mesoscale model MM5, the rainfall process of tropical storm
Fitow(0114) is simulated for 00:00 UTC 31 Aug. – 00:00 UTC 2 Sept. 2001. Mesoscale separation is performed
on the results with the filtering scheme. Analyses show that the MM5 model well reproduced the position and
intensity of heavy rain. Mesoscale characteristics of heavy rain were well represented in rainfall time scale,
rainfall area, stream field and divergence at lower and upper levels. The interaction between inverted typhoon
troughs and the mesoscale systems lead to heavy rain occurrence. The distribution of divergence fields at lower
and upper levels can have a kind of indication for the rainfall. Heavy rains are closely associated with topography
and land-sea distribution in South China. Weak instability is favorable to the generation of heavy rain. |
