Web20 okt. 2016 · The lowest layers of cloud are the most dangerous, and form from all of the same factors as fog. The difference is the fog “lifts” over either time or distance to form a stratus overcast. Also upslope flow may manifest itself as low clouds rather than fog when dry air is present at the surface.
WebPanel c) shows the lowest cloud layer reported by the ceilometer along with up to three mixing layer heights (MLH). In this example, the aerosol content is low throughout the day and a pervasive cloud layer prevents the CS135 ceilometer from retrieving mixing layer after the first three hours of the day. Boundary Layer Top Cloud Layer WebThe great advantage of these combination channels is that the low level cloud layers can be seen even when middle or upper level clouds may be present. The yellowish or dark reddish colours of the lowest cloud layers are easy to see in locations where the overlying cloud deck has breaks in it.
Web22 okt. 2024 · Although the overall performance of the algorithm was good, it is likely to miss the occurrences of high and multilayered clouds. This is due to the technical limits of the instrumentation: the vertical detection range of the ceilometer and occultation of the laser pulse by the lowest cloud layer. http://www.cas.manchester.ac.uk/resactivities/cloudphysics/background/classification/
