What weather conditions does Bai Yu jump off a boat to describe?

The poem describes the West Lake before and after the thunderstorm in summer, showing the ever-changing beauty of the West Lake.

The author described the scenery of the West Lake while drinking in Wang Hu Mansion. It was raining at that time, and it cleared up after the rain. The author first wrote it before the rainstorm. The scene is that dark clouds are rolling in the sky, just like thick ink rolling on the horizon, and distant mountains are faintly discernible in the rolling dark clouds. At this time, a rainstorm came like a note. The heavy rain hit the ship with white raindrops, splashing like thousands of pearls falling from the sky. Just as people were feeling the spectacular scene of heavy rain, a gust of wind rolled on the ground and blew away the dark clouds and heavy rain at once. When the clouds dispersed and the sun rose, the water below Wanghu Lake was as calm as a mirror and the air was fresh. Seen from a distance, water and the sky are the same. The poet is good at exaggerating the atmosphere, from the magnificence of the clouds pressing against the lake and the sudden rain, to the disappearance of the clouds, the ups and downs of the pen after the rain, and the leisurely description of the rapidly changing weather, which makes people dizzying and quite dramatic. In particular, the phrase "jumping off a boat in white rain" is the most vivid.
