點評
比較屬於中層的副高壓其下沉氣流所導致的~目前在TUTT外圍確實有比較明顯的乾區
UPPER LEVEL ANALYSIS INDICATES A TROPICAL UPPER
TROPOSPHERIC TROUGH (TUTT) TO THE NORTH OF TS 03W, WHICH IS
RESPONSIBLE FOR SUBSIDENCE TO THE NORTH AND LIKELY CAUSING THE
SUPPRESSION OF CONVECTION.
但JTWC說跟TUTT的下沉氣流有關
TUTT是熱帶對流高層槽~高層幅散通道相當順暢~反而會助長更多雲系發展
目前應該是有乾空氣捲入~所以才會抑制對流發展
