CIRRUS SHEATH Meaning and
Definition
-
Cirrus sheath refers to a meteorological term used to describe a cloud formation characterized by the presence of cirrus clouds surrounding or encircling a central core or nucleus. Cirrus clouds are high-altitude, thin, wispy clouds composed mainly of ice crystals and can be seen at heights ranging from 20,000 to 40,000 feet above the ground.
The cirrus sheath typically forms as a result of atmospheric conditions that favor the development of these clouds. It often occurs in regions of the atmosphere with strong wind shear, which is the variation in wind speed and direction at different altitudes. As the wind blows, it can cause the cirrus clouds to stretch and elongate in a direction perpendicular to the wind flow, forming a sheath-like appearance. This elongation is facilitated by the vertical wind shear, where the winds change direction and speed with increasing altitude.
The cirrus sheath is commonly associated with the approach of a warm front, which is a boundary between warm and cold air masses. As the warm air rises and ascends over the colder air, it undergoes cooling, causing the water vapor to condense and form cirrus clouds. The sheath formation may also indicate the presence of an approaching weather system, such as an extratropical cyclone or a tropical storm.
Overall, the cirrus sheath is a meteorological phenomenon characterized by the presence of cirrus clouds encircling a central core. It often indicates changes in atmospheric conditions and can be associated with the approach of a warm front or a weather system.
