altostratus การใช้

• Widespread opaque altostratus can produce light continuous or intermittent precipitation.
• This resulted in the genus name altostratus for stratiform types in the same altitude range.
• Altostratus can bring light rain or snow.
• If the precipitation increases in persistence and intensity, the altostratus cloud may thicken into nimbostratus.
• Altocumulus and Altostratus are the main cloud types found in the middle levels of the troposphere.
• Altostratus is usually composed of water droplets but may be mixed with ice crystals at higher altitudes.
• Altostratus tends to form ahead of a warm or occluded front, the altostratus gradually thickening into rain bearing nimbostratus.
• Altostratus tends to form ahead of a warm or occluded front, the altostratus gradually thickening into rain bearing nimbostratus.
• The "'altostratus undulatus "'is a type of altostratus cloud with signature undulations within it.
• The "'altostratus undulatus "'is a type of altostratus cloud with signature undulations within it.
• Altostratus is formed by the lifting of a large mostly stable air mass that causes invisible water vapor to condense into cloud.
• This cloud type normally forms above from altostratus cloud but tends to thicken into the lower levels during the occurrence of precipitation.
• This normally occurs with altostratus opacus, which can produce widespread but usually light precipitation, and with thicker clouds that show significant vertical development.
• If unstable altocumulus castellanus accompanies or takes the place of the main altostratus layer, cumulus congestus or cumulonimbus producing showers or thunderstorms may follow.
• The effect of gravity waves in clouds can look like altostratus undulatus clouds, and are sometimes confused with them, but the formation mechanism is different.
• They also can occur under altostratus cloud preceding a warm or occluded front, when cumulus usually lose vertical development as the sun's heat decreases.
• The best-known is cumulonimbus with mammatus, but the mamma feature is also seen occasionally with cirrus, cirrocumulus, altocumulus, altostratus, and stratocumulus.
• Altostratus most often takes the form of a featureless sheet of cloud but can be wavy ( undulatus ) as a result of wind shear through the cloud.
• Yesterday I saw a roughly 25 deg from the sun rainbowlike halo, and a sundog while the sun was in a cirrus-cirrostratus-altostratus cloud.
• The variety " undulatus " ( having a wavy undulating base ) can occur with any clouds of the species stratiformis or lenticularis, and with altostratus.
