Siamba typhoon | Observatory says computer forecast is just one tool: strength and wind forecast roughly

Typhoon "Siamba" hit Hong Kong earlier, and Siamba was always blown by a "light wind", but eventually the No. 8 typhoon signal would be hung. The Observatory later admitted that the computer forecast had been underestimating Siamba.

Choi Chun-wing, Senior Scientific Officer of the Observatory, explained at the Commercial Station today (4th) that the computer forecast model is only one of the tools for forecasting. roughly correct.

Cai Zhenrong pointed out that many computer forecast models had different predictions on the intensity and path of "Siamba" in the early days. The divergence is bigger, but the consensus forecast is weaker.

Put "wind detectors" near the storm to help analyze the intensity

He continued to point out that the Observatory cooperated with the flight service team to place "anemometers" near the storm. Before the wind season, drift buoys were also set up at sea to help analyze wind and air pressure, etc. Finally, the Observatory noticed through live data, etc. " There are signs of strengthening in Siamba, and the weather forecast has been gradually adjusted. It turns out that the observatory's prediction is generally correct.

The Observatory pointed out a few days ago that the computer model originally predicted that the area of ​​the Siam Barbie gale area was smaller. In fact, due to the stronger development of Siam Barbie than expected, the gale area covered Hong Kong, and the computer model "missed" also included the path. The path is to the east, so the Observatory's raw material No. 8 typhoon will continue until noon, and then the gale will be corrected to affect the local time.
