How does the author use imagery to connect Komura's emotions to the weather in the story, UFO in Kushiro?

The weather in this story reflects Komura's emotions at a given moment. For example, when Komura is in the car with Keiko and Shimao on the way to the restaurant, he begins to feel depressed about the loss of his wife, and the weather is described as "dark and desolate" (13).
