Storm-scale - Referring to weather systems with sizes on the order of individual thunderstorms. See synoptic scale, mesoscale.
A storm-scale or mesoscale boundary separating thunderstorm-cooled air (outflow) from the surrounding air; similar in effect to a cold front, with passage marked by a wind shift and usually a drop in temperature.
A storm-scale region of rotation, around 3-10 kilometres in diameter and often found in the left rear flank of a supercell (or often on the eastern, or front, flank of an HP storm).
Mesocyclone- A storm-scale region of rotation, typically around 2-6 miles in diameter and often found in the right rear flank of a supercell (or often on the eastern, or front, flank of an HP storm).
Mesocyclone - A storm-scale region of rotation, typically around 2-6 miles in diameter. The circulation of a mesocyclone covers an area much larger than the tornado that may develop within it.
WATERSPOUT A small, weak tornado, which is not formed by a storm-scale rotation. It is generally weaker than a supercell tornado and is not associated with a wall cloud or mesocyclone.
In most cases the term is reserved for small vortices over water that are not associated with storm-scale rotation (i.e., they are the water-based equivalent of landspouts).
[Slang], a tornado that does not arise from organized storm-scale rotation and therefore is not associated with a wall cloud (visually) or a mesocyclone (on radar).
Bear's Cage Slang for a region of storm-scale rotation, in a thunderstorm, which is wrapped in heavy precipitation.
A region of storm-scale rotation, in a thunderstorm, which is wrapped in heavy precipitation. This area often coincides with a radar hook echo and/or mesocyclone, especially one associated with an HP storm.
The term mesoscale is a size scale referring to weather systems smaller than synoptic scale systems but larger than storm-scale cumulus systems. Horizontal dimensions generally range from around 50 miles to several hundred miles.
Size scale referring to weather systems smaller than synoptic-scale systems but larger than storm-scales ???ystems. Horizontal dimensions generally range from around 50 miles to several hundred miles.
It is the most destructive of all storm-scale atmospheric phenomena. They can occur anywhere in the world given the right conditions, ...
Dry slot should not be confused with clear slot, which is a storm-scale phenomenon.
The strongest visual clues in identifying this type of supercell usually are the curving inflow bands and mid-level cloud bands which wrap around the updraft, both suggestive of storm-scale rotation.
wraps west- or south-westwards into the southern and eastern parts of a synoptic scale or mesoscale low pressure system. A dry slot is seen best on satellite photographs. A dry slot should not be confused with clear slot, which is a storm-scale ...
