There is no significant long-term trend during 1951-2017 in the numbers of tropical cyclones  with maximum winds of 66.37 km h-1 or higher forming in the western North Pacific and the South China Sea . There are substantial inter-decadal variations in basin-wide TC frequency and intensity in the western North Pacific . Numbers of strong TCs  also show no discernible trend since 1977 when complete wind-speed data near TC centre become available . According to Cinco et al. , for TCs in the Philippines there are no significant trends in the annual number of TCs during 1951-2013. Their analysis showed that the Philippines have been affected by fewer TCs above 124.93 km h-1, but affected more by extreme TCs . There has been a significant northwestward shift in TC tracks since the 1980s, and a detectable poleward shift since the 1940s in the average latitude where TCs reach their peak intensity in the western North Pacific  .
