Note from Ben Jou

• I have enclosed analysis plots of 850hP
  equivalent potential temperature and winds and
  700 hPa dew point depression and winds for two
  heavy rain cases occurred in the past years.
• I have also enclosed similar plots of 24-72
  forecast from WRF model with CWB NFS as initial
  condition and with horizontal resolution of 15
  km.
• These model outputs seem to suggest that there
  will be a drying trend in south Taiwan while the
  frontal system propagating southward from China.
  The system will be more organized on 30th May and
  higher probability of heavy rain in the Taiwan
  area is expected.
