cirrocumulus |
| noun
- (context, physics, Meteorology) A principal high-level cloud type appearing as a thin, white patch of cloud without shadows, composed of very small droplets in the form of grains or ripples. The elements may be merged or separate, and more or less regularly arranged; they subtend an angle of less than 1° when observed at an angle of more than 30° above the horizon. Holes or rifts often occur in a sheet of cirrocumulus. Abbreviated Cc.
|
cirrostratus |
| noun
- (meteorology) A principal high-level cloud type appearing as a whitish veil, usually fibrous but sometimes smooth, which may totally cover the sky and which often produces halo phenomena, either partially or completely. Sometimes a banded aspect may appear, but the intervals between the bands are filled with thinner cloud veil. The edge of the veil of cirrostratus may be straight and clean-cut, but more often it is irregular and fringed with cirrus. Some of the ice crystals that comprise the cloud are large enough to fall and thereby produce a fibrous aspect. Cirrostratus occasionally may be so thin and transparent as to render it almost indiscernible, especially through haze or at night. At such times, the existence of a halo may be the only revealing feature, such as producing a halo around the moon. Abbreviated: Cs.

cyclogenesis |
| noun - (meteorology) the process which leads to the formation of tropical storms, cyclones and hurricanes; typically involves an interaction that leads to vertical wind shear
|
cyclone |
| noun
- A system of winds rotating around a center of low atmospheric pressure. A cyclone rotates counterclockwise in the northern hemisphere and clockwise in the southern hemisphere (opposite to that of an anticyclone). Modern meteorology restricts the use of the term cyclone to the cyclonic-scale circulations. But, it is still applied popularly to the more or less violent, small-scale circulations such as tornadoes, waterspouts, and dust devils (which may in fact exhibit anticyclonic rotation), and even, very loosely, to any strong wind. Because cyclonic circulation and relative low atmospheric pressure usually coexist, in common practice the terms cyclone and low are used interchangeably. Also, because cyclones nearly always are accompanied by inclement (sometimes destructive) weather, they are frequently referred to simply as storms.
- A Southeastern and Indian Ocean weather phenomenon that results in wind speeds of around 150 to 200 km/h.
|
cyclonic |
| adjective
- of, or pertaining to a cyclone
- (meteorology) rotating in the same direction as the Earth i.e. anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere
