Cold temperatures and high clouds came together to form a brilliantly colorful sunset over many parts of the Middle Tennessee area on Wednesday.
In the United States, late fall and winter typically produce the most vivid and colorful sunsets. Cooler temperatures allow for better air circulation. When the air can circulate more freely, dust particles and pollutants are scattered more effectively. According to the National Ocean and Atmospheric Administration (NOAA), when the air is cooler and can circulate better, the light rays from the sun can reach the ground easier, thus allowing the various colors in the spectrum to be more clearly visible. When you have clouds present, red-orange rays of the spectrum are amplified and can produce spectacular sunsets. When there is a high presence of oxygen and nitrogen in the air, the blue and violent colors of the light spectrum are also more evident. When the three weather conditions combine, you are left with breathtaking colors illuminating the sky.
