Relationship to Severe Weather
A defining feature of severe thunderstorms, the tail cloud serves as a critical indicator of strong atmospheric instability, particularly in the context of supercells. Typically associated with severe thunderstorms, the tail cloud is closely linked to the presence of a wall cloud and signifies intense atmospheric instability in the vicinity.
This distinct cloud feature extends from the precipitation area of a supercell towards the wall cloud, demonstrating the dynamic relationship between severe weather phenomena and the formation of tail clouds.
The motion of a tail cloud is characterized by rapid upward movement directed towards the wall cloud, indicating the potential for tornado development in the region where these two cloud features intersect. This motion pattern signifies the inflow of warm, moist air into the storm system, fueling its intensity and contributing to the severe weather conditions often associated with tail clouds.
Although tail clouds are considered relatively uncommon, their presence during intense thunderstorm activity underscores their significance in identifying and understanding severe weather events.
Cauda Cloud Types
Cauda cloud types, also known as tail clouds, are distinctive features observed in association with severe weather conditions, particularly in the context of supercells. These clouds are a specific cauda cloud feature, attached to the wall cloud of cumulonimbus clouds, indicating intense convective activity. Tail clouds exhibit a horizontal, tail-shaped appearance extending from the precipitation cascade region to the wall cloud.
One notable characteristic of tail clouds is their rapid upward motion often observed near the junction of the tail cloud and wall cloud. While these clouds are frequently mistaken for flumen clouds, a cloud type besides tail clouds, they can be differentiated by their size and altitude. Tail clouds are smaller and directly connected to the wall cloud, whereas flumen clouds are larger and positioned higher in the sky.
In meteorological classification, the abbreviation for this cloud type is 'Cb cau,' emphasizing its association with cumulonimbus clouds and the severe weather phenomena they signify.
