IN 1933 Bergeron1 postulated that rain falls only from clouds which contain both water drops and ice crystals. Natural cumulus clouds at temperatures above -13° C. often contain only supercooled ...

Fallstreaks, often called “hole punch clouds,” occur when conditions in a mid-or-high level cloud deck consist of supercooled water droplets — or water droplets that can actually exist as a ...

Despite decades of research efforts and debate, a full understanding of the origin of the anomalous properties of liquid water, in particular when supercooled, is not yet in sight. This focus ...

However, it is important to note that heat and water vapor emitted by industries may also play a role in the freezing of supercooled liquid clouds. The discovered plumes of reduced cloud cover are ...

As people living through the recent Cyclone Alfred will know, clouds can carry huge amounts of water. How much that can be ...
