The first answer is correct: "They suggest that the heat is stifling, giving the poem an oppressive mood".
The author begins the poem with the sentence cited above. The use of the expression "rend open" plus the use of the imperative mode, suggest some sort of desperation caused by the heat. That is why the author prays for wind (an unbeatable natural force) to come and defeat heat, ending the suffering.
The Kingdom of Saudi Arabia<span> is a country situated in </span>Southwest Asia<span>, the largest country of </span>Arabia<span>, bordering the </span>Persian Gulf<span> and the </span>Red Sea<span>, north of </span>Yemen<span>. Its extensive coastlines on the Persian Gulf and Red Sea provide great leverage on </span>shipping<span> (especially </span>crude oil<span>) through the Persian Gulf and </span>Suez Canal<span>. The kingdom occupies 80% of the </span>Arabian Peninsula<span>. Most of the country's boundaries with the </span>United Arab Emirates<span> (UAE), </span>Oman<span>, and the </span>Republic of Yemen<span> (formerly two separate countries: the </span>Yemen Arab Republic<span> or </span>North Yemen<span>; and the </span>People's Democratic Republic of Yemen<span> or South Yemen) are undefined, so the exact size of the country remains unknown. The Saudi government estimate is at 2,217,949 square kilometres, while other reputable estimates vary between 2,149,690 and 2,24</span><span>0,000 sq. kilometres. Less than 1% of the total area is suitable for cultivation, and in the early 1990s, population distribution varied greatly among the towns of the eastern and western coastal areas, the densely populated interior oases, and the vast, almost empty deserts.
