I infer you are referring to this poem;
Thunder blossoms gorgeously above our heads,
Great, hollow, bell-like flowers,
Rumbling in the wind,
Stretching clappers to strike our ears . . .
Full-lipped flowers
Bitten by the sun
Bleeding rain
Dripping rain like golden honey—
And the sweet earth flying from the thunder.
Answer:
It creates a positive impression.
Explanation:
Remember, it all starts with the Thunder storm which creates a positive feeling for the poet; this positive feeling is evident in the use of expressions such as gorgeously, honey, flowers. Overall the the storm led to a "sweet earth".
