TAIPEI (TVBS News) — Taiwan's former weather chief issued a public alert Thursday (Aug. 28) as meteorological conditions across Southeast Asia signal potential changes for the island's weather patterns. Cheng Ming-dean (鄭明典), former director of the Central Weather Administration, Taiwan's national meteorological service (中央氣象署), warned residents through social media about increased rainfall probability driven by an intensifying monsoon trough system. The veteran meteorologist's Facebook post highlighted emerging atmospheric dynamics that could reshape Taiwan's weather outlook in coming days.
Cheng's detailed analysis revealed a powerful wind corridor extending from the Bay of Bengal (孟加拉灣) through Southeast Asia's Indochina Peninsula and across the South China Sea toward the Philippines. The meteorologist described how this monsoon trough, commonly referred to as a typhoon breeding ground, has positioned itself in the equatorial Northwest Pacific region. The system's current southerly location suggests Taiwan will experience only limited weather effects from this atmospheric development.
The former weather director emphasized the complexity of meteorological forecasting, cautioning against overreliance on computer models given Taiwan's unique geographic position. Cheng specifically highlighted how the Pacific high-pressure system north of Taiwan frequently disrupts prediction accuracy, creating challenges for weather professionals. The dynamic interplay between monsoon systems and trade winds represents a critical atmospheric mechanism that can spawn tropical cyclones throughout the region. ◼
