Classic-style hook echo of the F5 1999 Bridge Creek-Moore tornado.. A hook echo is a pendant or hook-shaped weather radar signature as part of some supercell thunderstorms.It is found in the lower portions of a storm as air and precipitation flow into a mesocyclone, resulting in a curved feature of reflectivity.
Due to this, these storms are sometimes referred to as rotating thunderstorms. [2] Of the four classifications of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the overall least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the ...
A mesocyclone is a meso-gamma mesoscale (or storm scale) region of rotation , typically around 2 to 6 mi (3.2 to 9.7 km) in diameter, most often noticed on radar within thunderstorms. In the Northern Hemisphere , it is usually located in the right rear flank (back edge with respect to direction of movement) of a supercell , or often on the ...
Local Radar Image. What is a supercell? A supercell is a large thunderstorm that has a deep and persistent rotating updraft. It looks like a very tall storm cloud that has an anvil or elongated ...
The near 26 inches of rain at Fort Lauderdale-Hollywood International Airport was a 1-in-1,000-year storm.
Around 100 properties were damaged by what police called a ‘localised tornado’ that whipped through Stalybridge, Tameside, on Wednesday.
The formation of descending reflectivity cores in supercell thunderstorms is a complex process influenced by various atmospheric dynamics. Research, particularly involving high-resolution radar data and numerical simulations, has identified several mechanisms through which DRCs can develop:
Vertical cross-section through a supercell showing the BWER. The bounded weak echo region, also known as a BWER or a vault, is a radar signature within a thunderstorm characterized by a local minimum in radar reflectivity at low levels which extends upward into, and is surrounded by higher reflectivities aloft, forming a kind of dome of weak echoes.
