What is the author's style in Portrait of a Couple at Century's End by Sherod Santos?

Throughout the poem's early stanzas, Santos uses rain to imply an ominous sense of discontent pervading modern culture. In the first stanza, the rush-hour traffic is slowed by the rain. In the second and third stanzas, lines 6 through 15, it is raining in the country being covered on the television news. The couple inside their house are aware of the rain, which drives them to take themselves back to the summer in their conversation. The rain defines the mood of the entire poem.
