When the tropical cyclone "Lion Rock" approached Hong Kong last weekend, the time when the No. 8 gale or storm signal was issued by the Observatory caused controversy, and the statement has been changed many times.
The former assistant director of the Observatory and the spokesperson of the Hong Kong Meteorological Society, Leung Wing-wu, stated on the radio program today (11th) that the method of disseminating information to the public by the Observatory can indeed be improved, but the "Lion Rock" is an "unusual number" in tropical cyclones. There are quite a few variables. The Observatory originally wanted to provide the public with a more complete and accurate message, but it was a pity that "God's will trick people."
He also pointed out that the wind force of the "compass" is stronger than that of the "Lion Rock", and may even be much stronger. According to current predictions, it may be closer to Hong Kong than the "Lion Rock".

The "compass" wind is stronger but may be affected by the dry monsoon
Liang Rongwu mentioned on the Hong Kong and Taiwan program that although the "Lion Rock" is farther away from Hong Kong, the wind caused by the airflow brought by the northeast monsoon to Hong Kong along the Taiwan Strait at that time caused the wind to become stronger.
As for the tropical cyclone "Compasses" which will enter 800 kilometers of Hong Kong at night, he described it as "rule-abiding".
He pointed out that although the "compass" has stronger wind than the "Lion Rock", it is closer to Hong Kong.
However, since the northeast monsoon does not pass through the Taiwan Strait and is northerly, the wind may not be strong; coupled with the relatively dry monsoon this time, the power of the "compass" may be weakened.
In addition, the "compass" moves fast and has a shorter impact time.

Refers to being ineligible to criticize if you don't have the basic facts
The Observatory has been criticized for its handling of the "Lion Rock" typhoon signal. Liang Rongwu said that he used to fight the wind "too little gaze", but he could not sleep yesterday, because he saw some comments that the Observatory was negligent, and doubted that he would swear if he did not have the data. , There is no right to criticize, "The Observatory does not sleep and does its own work every day. The weather has always been unpredictable. This is the fate of the Observatory. But criticism should be objective. Some of the discussions are based on data and basis, and the criticisms are pertinent, but many of them are unreasonable and swearing."
He mentioned that some netizens were very mindful. They listed the wind speed data of the eight wind speed stations of the Observatory on Saturday, and calculated the average wind speed at each station, which was about 50 kilometers per hour. It was not at the gale level but was very close. The wind at Cheung Chau and the airport is very strong, reaching the level of gale. "There are many people living in this place, and there are planes taking off and going, don't you need to go to No. 8?" He checked the wind level last Friday, and there was no time throughout the day. The continuous wind speed reached the standard of wave 8, so last Friday it was completely in line with the scientific requirements to only hang the 3rd typhoon signal.
Refers to the Observatory’s attempt to provide a more precise wave-fall time, which is counterproductive.
However, Liang Rongwu agreed that the Observatory has changed its interpretation of the "falling wave" time on Saturday several times, and there is room for improvement in the dissemination of information. The observatory is struggling to meet the expectations of the public, and there is a tension between it and the science. He really wants to be a citizen of the wave of information, but the "Lion Mountain" is getting better and twisted. This is often the case. It’s a contradiction. The Observatory’s words "Change to No. 3 Typhoon Signal at 3 O'clock" must be the people’s favorite, because everyone is clear and can adjust the itinerary, but sometimes the public’s expectations are that the scientific ability of the family is not time-consuming. can reach."
He explained that although the "Lion Rock" was far away from Hong Kong last Saturday, under the influence of the northeast monsoon and certain air currents, the wind was still very strong, and the gale would last a little longer. On Saturday afternoon, there was another organized Rain bands affect Hong Kong. When strong rain bands are superimposed, the wind will be stronger, so the waves cannot fall: "We can only make people out of the sky, but the observatory will issue a strong monsoon signal from Thursday, after typhoon signal No. 3, and then 8 Nothing is wrong with the typhoon signal." He also pointed out that if new information and variables are encountered when forecasting the weather, the information sent to the public must be adjusted. If the original forecast is found to be wrong, it must be changed and continue. It is irresponsible to go wrong.
