With their towering heights and expansive lengths, the Sierra Madre Mountain Ranges (SMMR) and the Cordillera Mountain Ranges (CMR) have long been believed to act as natural barriers to typhoons. To scientifically measure the effectiveness of the SMMR and CMR, Bagtasa and Racoma analyzed the ranges’ impact on two types of typhoon hazards: the rain and the wind. In the long run, moving beyond minimizing the Sierra Madre and the Cordillera Mountain Ranges as mere typhoon barriers toward understanding their broader ecological implications remains more crucial than ever, opening the door to better environmental protection and even typhoon risk management.
