Guangzhou to experience highest astronomical tide of the year from June 16-18
Hızlı Bakış
- Guangzhou is predicted to experience the highest astronomical tide of the year from June 16 to 18.
- This phenomenon is caused by a combination of factors including the moon's proximity to Earth, a syzygy of the sun, moon, and Earth, and the moon's northernmost position.
- Heavy rainfall in May and June is also expected to exacerbate the situation, potentially leading to flooding in low-lying areas.

Neden Önemli?
Guangzhou is predicted to experience the highest astronomical tide of the year from June 16 to 18, with the highest tide level occurring for three consecutive days. This is due to a combination of astronomical factors and meteorological conditions.
中新网广州6月13日电 (郭军 李建基)据广州市五羊天象馆预测：今年进入农历五月份，广州地区的江河乃至广东沿海，将会发生今年以来潮位最高的天文大潮。最高潮位将会连续出现三天(6月16日至18日)。6月18日以后，最高潮位将会明显回落。
造成这次天文大潮的主要因素是：6月15日7时20分，月球运行到距离地球最近的地点，两者相距只有357197千米，从而引发“近地大潮”；6月15日10时54分(朔)，太阳、月球和地球依次排列成近似一条直线(三星一线)，从而发生“朔望大潮”；6月15日14时，月球运行到地球北半球的最北位置，接近地球北纬28度的上空，从而出现“回归大潮”。这三个天文大潮在几个小时内接连发生，从而把今年以来的天文大潮的潮位推向最顶峰。
气象因素是：每年阳历的5月和6月，是广州地区降水最多的月份。雨量大，江河水位会上涨，洪水可能发生。因而，上游洪水下泄，下游潮水上溯，从而把水位叠加到最高峰。
在有江海的地区，一天之中，多数会出现两次高潮和两次低潮。在广州的珠江河段，这三天最高和最低的潮位，预计分别出现在6月16日的13时17分(高潮)和22时45分(低潮)；17日的13时56分(高潮)和23时30分(低潮)；18日14时45分(高潮)和19日0时11分(低潮)。
这次广州珠江河段的最大潮差(潮位的最高减最低)，将接近3米。俗话说：“大河涨水小河满，大河退水小河干。”最高潮水来临时，广州有些低洼地面，可能被江水淹没。最低水位出现时，一些小河涌，滩涂成片显露。有兴趣的潮汐观测爱好者，可在上述的时间，采用手机拍摄珠江的水文水位状况。(完)
