When does summer dawn in the three northeastern provinces? How long is the evening?

In the three northeastern provinces, the summer sky usually begins to brighten slowly around 2: 30 in the morning. The time of the sun above the horizon is about 15 hours, while the day length in Mohe County of Heilongjiang Province is more than 17 hours. The difference between the two ends of China is more than 4 hours.

In summer, during the summer solstice, the sunshine time in China is getting longer and longer from south to north. However, because the Yangtze River Basin in central China has entered the rainy season from summer solstice, the sunshine time is generally short, and the total sunshine hours during the summer solstice are between 60 and 90 hours.

Extended data:

During the summer solstice in China, the areas with sunshine 120- 150 hours are mainly distributed in the northeast, northern North China, eastern Northwest China and most of Tibet, and the time for the earth to bathe in sunshine can reach 8- 10 hours every day.

In most parts of Xinjiang, western Inner Mongolia and northern Tibet, the sunshine exceeds 150 hours during the summer solstice, and the average daily sunshine time exceeds 10 hours, which brings abundant solar energy resources here. This is also the reason why solar energy resources in the north can be widely used.
