Affected by less rainfall, the tidal bore in Qiantang River will be slightly smaller this year than last year. Is it still worth seeing?

Many people have seen the spectacular and shocking tides of Qiantang River. However, according to the staff of Hangzhou Forestry and Water Affairs Bureau, due to the unusually high temperature and less rain, the tide in Qiantang River will be greatly reduced this year compared with last year. However, the formation of tides in Qiantang River is not only related to rainfall, but also influenced by astronomical and geographical factors. Especially around the 15th day of the eighth lunar month, the sea water will be subjected to a huge tidal force, and the position will form a spring tide, so there is still a spring tide in Qiantang River this year.

According to local meteorological data, the cumulative rainfall in Qiantang River basin this year is about 25% less than last year, which means that the ability of the tide to rise to the new moon is relatively weakened, and the tidal bore can not reach the spectacular height last year. Some experts speculate that the maximum height of tidal bore this year is only about 1.4 meters. Although the spring tide may not be as good as last year, it still has good ornamental value. Because the earth, the moon and the sun are on the same straight line around August 15, the huge tidal force will pour the tide back into the trumpet-shaped Hangzhou Bay, and because of its strong impact, it will break out after being blocked by a narrow crossing, forming a spring tide.

It is predicted that this year's Qiantang River tide will appear on August 18, and the early tide will appear around 2 am, when the tidal bore is relatively small, while the late tide in the afternoon will still cause spectacular scenes. Moreover, this year's tide-watching incorporates new technologies, realizing the intellectualization of tide-watching, and also providing online live broadcast, so that some people who can't go to the scene can also see the tidal bore simultaneously. Coupled with this year's moisture-proof measures and safe tide-watching environment, it attracted more citizens to watch.

The spring tide in Qiantang River is not only a magical natural phenomenon, but also a natural product of geography, climate, astronomy and other factors. It not only allows ordinary citizens to see the shocking natural landscape, but also allows photographers and astronomy enthusiasts to get inspiration and works through the tidal bore, and also provides reference opportunities for continuing to explore natural research. So its ornamental value is still very high.
