The Pearl River, also known as the Yue River, is the second largest river in China and the third longest river in China. The Pearl River in the narrow sense refers to a 96-kilometer-long waterway from Guangzhou to the mouth of the sea, named because it flows through the famous Haizhu Island (Shi), and later gradually became the general name of the Xijiang, Dongjiang, Beijiang and the rivers on the Pearl River Delta.
In terms of latitude and longitude, the Tropic of Cancer passes through Guangzhou. Guangzhou has the Tropic of Cancer mark, on the slope of Sanjiazi in Yaumapu Village, Taiping Town, Conghua District (23°26'28"44 north latitude, 113°28 56 east longitude).16), it is currently the highest height and largest symbol tower on the Tropic of Cancer in the world.
The water depth of the Pearl River in Guangzhou and below is about 3-10 meters, the water volume is large, the river surface is wide, and there are embankments on both banks.
The daily minimum temperature in Guangzhou is above 0, and in 2016, which is relatively recent to the present, the temperature dropped sharply under the influence of strong cold air in the north, and the national meteorological station in Luogang, Guangzhou, measured 12 degrees, the Wushan Weather Station located in the urban area measured 19 degrees. The Pearl River has a large amount of water and an open river surface, and only from the perspective of temperature changes, the Pearl River does not have the conditions for freezing in the shallow water of the river beach, and there will be no river freezing. It should be all year round, and the big river flows.
However, it is said that in the 50s and 70s of the last century, there was a drastic cooling in Guangzhou, falling below freezing. Could it be that there is such a thin layer of ice in the shallows by the river?I searched on the Internet, and in the last century, the information that Guangzhou cooled down to below zero can be found, and the freezing phenomenon is really not found
