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 (卷云) are high clouds. They look like feathers. ...

Cumulus clouds are formed by small thermals (upward-moving air parcels heated by contact to the warm ground) where condensation occurs and they grow to extend vertically throughout the troposphere. Their vertical extent is controlled by the depth of the unstable layer, while their horizontal extent...
In particular, low-level stratiform clouds are common in the Arctic but are, due to their low altitude, challenging to observe and characterize with remote-sensing techniques. The availability of reliable ground-based observations as reference is thus of high importanc...
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...

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...
