Show mini Does a red sunset actually tell us anything about tomorrow's weather? The old saying is frequently heard about a red sky at the end of the day-that it means clear, cold weather. IN practically all sections of the United States the prevailing direction of the movement of the gas layer circling the earth (the weather) is west to east. Today's weather was actually over some point westward yesterday-probably several hundred miles away. If the sun sets red, that means dry, dusty air is toward the west, between the viewer and the sun-hence the red color. If the air to the west is dry and dusty and is moving mov-ing toward the viewer, it will be overhead in coming hours. Chances are the weather will be fair in the immediate future. THE reason for assuming i red sunset means colti weather lies in the fact that clearing weather usual!; TH follows the passage of a coU?ree front. In the winter roontbj,U most of the fronts are cold ri and, thus, more often thai nlj not, a clear weather sign occurs oc-curs behind i cold front. r. |
