A storm without rain is called a dry thunderstorm.
Dry thunderstorms are characterized by thunder and lightning but with little or no rain or precipitation reaching the ground.
The rain often occurs with the dry thunderstorm in some cases although the rain if it does occur will evaporate before it hits the surface as a result of dry air conditions, which is also known as virga.
The edge of a storm is called a gust front when referring to thunderstorms the gust front is also the edge of the downdraft.
In tropical cyclones, the edge of the tropical cyclone is the eyewall which is also the edge of the strongest winds.
Shelf cloud can also be seen at the leading edge of some thunderstorms or cold fronts.
The bear's cage in a storm is the area of heavy rain and hail which surrounds a rotating updraft, which could be potentially hiding a tornado.
The bear's cage in a storm is a dangerous area as a result of the possibility of a tornado being obscured by the precipitation, which leads to low visibility and even the potential for hail, strong winds and even flash floods.
The bear in bear's cage is the rotating updraft, which can produce a tornado.
The cage in bear's cage is the heavy precipitation, which can be hail or rain which surrounds the rotating updraft, acting like a cage.
The bear's cage is dangerous and a risky area as a result of the tornado which can be hidden within the precipitation, making it difficult to avoid and see.
Visibility in a bear's cage is also significantly reduced as a result of the heavy precipitation, making it challenging to assess the intensity of the storm and any potential threats.
The bear's cage is also particularly relevant in HP supercells, in which the tornado is often rain wrapped.
The term bear's cage is widely used by storm changes in order to describe the specific hazardous storm structure.
