What was measured
- Mean of 28 station maximum hourly mean winds94km/h
- Waglan Island161km/h
- Cheung Chau157km/h
The 28-station value is the arithmetic mean of the issuing agency’s maximum hourly mean winds in Table 3.5.1. Waglan Island and Cheung Chau use maximum 60-minute mean winds in Table 3.5.2. These reference statistics use station measurements, not replay-model estimates. Their averaging windows differ and are not directly comparable with the replay’s ten-minute model estimates.
