are clouds different colors
The water vapor attaches itself to condensation nuclei which can be anything from dust to microscopic particles of salt and debris. Once the vapor has been cooled to saturation, the cloud becomes visible. All weather-producing clouds form in the troposphere, the lowest major layer of the atmosphere. Nimbostratus clouds are smooth layers of gray, which often cannot be seen clearly because of the precipitation falling from them. Low clouds: Stratus, cumulus and stratocumulus clouds are based at altitudes of 6,000 feet or lower. Stratus clouds appear as smooth, even sheets; light rain and drizzle often fall from them; light snow or freezing drizzle during the winter. Fog is merely a stratus cloud reaching to, or forming on the ground. A viewer on the ground can distinguish the clouds at different heights according to the relative timing of their color change during sunset (Figure 8). Clouds at night are visible only when there is a source of light. Thin clouds will generally appear white under the white moonlight. For the bottom of dense low clouds, the main light source is the light from the ground (usually orange or white light) originated from street lamps and other light sources in cities. They bring life-giving rain to different regions. All of us at one time or another have looked to the sky and watched the clouds. Clouds can be picturesque; they can also appear menacing, even threatening, suggesting a sudden, perhaps even violent turn in the weather. Clouds of the genus nimbostratus tend to bring constant precipitation and low visibility. This cloud type normally forms above 6,500 feet (2.0 km) from altostratus cloud but tends to thicken into the lower levels during the occurrence of precipitation. The top of a nimbostratus deck is usually in the middle level of the troposphere. The colour of a cloud also depends on the colour of the light that illuminates it. When sunlight passes through thick layer of atmosphere and dust particles at sunset, blue colour is scattered by Rayleigh Scattering and only red-to-orange color remains (see Question 2). The list of cloud types is a summarisation of the modern system of cloud classification according to their height, forming mechanism and other characteristics that have been adopted universally. The essentials of the modern nomenclature system for tropospheric clouds were proposed by Luke Howard, a British manufacturing chemist and an amateur meteorologist with broad interests in science, in an 1802 presentation to the Askesian Society. Since 1890, clouds have been classified and illustrated in cloud atlases. The effect is much like shining a red spotlight on a white sheet. Since the Earth is spherical, the clouds at different heights turn red at different time when the sun crosses the horizon (Figure 7). Just before the sunset, the color of low clouds (e.g. stratus) will turn red first. Stratocumulus clouds are similar to altocumulus in that they can appear in a wide variety of different shapes and textures. Clouds of great vertical development: These are the cumulonimbus clouds, often called a thunderhead because torrential rain, vivid lightning and thunder come from it.
