Sometimes, cirrus get low and thick. This might mean a warm front is coming. A warm front occurs where warm and cold air meet. The warm air rises. It goes over the cold air. This leads to clouds. When you s...
Low clouds form closer to Earth’s surface. In fact, low clouds can even touch the ground. These clouds are called fog. Middle clouds are found between low and high clouds. Another way clouds are named is by their shape. Cirrus clouds are high clouds. They look like feathers. Cumulus ...

which lasts for approximately 15–30min. The air of the downdraft reaches the ground, as a cold core, and changes the surface wind pattern. This change may initiate a new thermal at a neighboring location, which might grow to a new cell. The downdraft interferes with the updraft at the ...
On the link between ocean biota emissions, aerosol, and maritime clouds: Airborne, ground, and satellite measurements off the coast of California [1]聽Surface, airborne, and satellite measurements over the eastern Pacific Ocean off the coast of California during the period between 2005 and 2007 ar...
(SfM) techniques enabled the possibility to characterize this variability with low efforts. The study aims to evaluate, compare and cross-validate the potentiality and the limits of several tools (UAV, MA, MLS) to assess the vine canopy size parameters (thickness, height, volume) by processing ...
Noctilucent clouds are visible during the summer months when the mesosphere is at its coldest at the poles, according toEarth Sky. When temperatures are low enough, water vapor freezes onto the dust particles, forming ice crystals. Whenthe sunilluminates them from below, these ice crystals reflec...
We use a classified ALS point cloud whose points are labelled according to their object class (building, ground, and unclassified). To group points belonging to one building, points are clustered by applying the DBSCAN algorithm [50]. As a result, different buildings will have different cluster...
For high clouds, the high LWP in daytime and low LWP in nighttime become significant, showing obvious response to solar radiation. The mean LWPs at WH, XN and JZ are 0.322, 0.469 and 0.243 kg/m, respectively, and the high LWP at XN may be related to the dynamic uplift of the nearby...
When low-level supercooled liquid-bearing clouds are detected and no exact retrieval is available for determining the LWP that is assigned to these clouds, we rely on a fill value based on the median LWP value retrieved by ground-based observations at Summit (see below). A total of ∼6.3...
