about sunsets
tramonti
Sunset, also called sundown in some American English dialects, is the instant when the trailing edge of the sun's disk disappears below the horizon in the west. It should not be confused with dusk, which is the point at which darkness falls, some time after the beginning of twilight when the sun itself sets.
The sunset is often more brightly colored than the sunrise,[citation needed] with the shades of red and orange being more vibrant. The atmosphere responds in a number of ways to exposure to the sun during daylight hours. In particular, there tends to be more dust in the lower atmosphere at the end of the day than at the beginning. During the day, the sun heats the surface of the Earth, lowering the relative humidity and increasing wind speed and turbulence, which serves to lift dust into the air. However, differences between sunrise and sunset may in some cases depend more on the particular geographical features of the location from which they are viewed. For example, on a west-facing coastline, sunset occurs over water while sunrise occurs over land.colors of the sunsets

The red and orange hues of the sky at sunset and sunrise are caused by scattering of sunlight off of dust particles, soot particles, other solid aerosols, and liquid aerosols floating in the earth's atmosphere. The enhanced red and orange colors at sunset and sunrise are mathematically explained by Mie theory or the discrete dipole approximation. The brilliance and intensity of the colors of sunsets are typically greater than sunrises, since there are generally more particles in the evening air than in the morning air. Nightime air is usually cooler and less windy which allows the dust and soot particles to settle out of the atmosphere, reducing the amount of Mie Scattering and the amount of red and orange scattered light at sunrise. Sunrise color intensities can however exceed sunset's intensities when there are nighttime fires, volcanic eruptions or emissions, or dust storms to the east of the viewer. A number of eruptions in recent times, such as those of Mount Pinatubo in 1991 and Krakatoa in 1883, have been sufficiently large to produce remarkable sunsets and sunrises all over the world.
Sometimes just before sunrise or after sunset a green flash can be seen. thanks to Wikipedia. what is a fanlisting?
fanlisting
A fanlisting is simply an online listing of fans of a subject, such as a TV show, actor, or musician, that is created by an individual and open for fans from around the world to join. There are no costs, and the only requirements to join a fanlisting are your name and country. Fanlistings do not have to be large sites (although some are) - they are just a place where you can have your name listed along with other fans of the same subject. TheFanlistings.org is the original (but not only) web directory for fanlistings, dedicated to uniting fans across the globe.The Fanlistings.org |
