What are the signs of seeing clouds at night?

Seeing clouds at night is a natural phenomenon and there are no special signs. However, there are some explanations for seeing clouds at night:

1. Seeing clouds at night may indicate that the weather will be good tomorrow and it will be a sunny day. This is because the principle of evening glow is due to the sunlight passing through the thick atmosphere and being scattered by a large number of air molecules around sunrise and sunset.

2. Another explanation is that the appearance of the evening glow may mean that the weather is about to clear up. For example, if you see a bright red and golden sunset at night, it may indicate that the weather has cleared up or the clouds have broken up in the upper reaches to the west of us, allowing sunlight to shine through to create the sunset, indicating that the rain clouds hanging over the local area are about to move eastward. If we move, the weather will clear up.

However, these are just conclusions based on some observations and theories, and the actual situation may vary due to geographical location, climate and other factors. It is worth noting that these observations and theories do not guarantee the accuracy of predictions, and weather forecasting remains the most reliable way.
