A macroburst is an outward burst of strong winds at or near the surface with horizontal dimensions larger than 4 km (2.5 mi) and occurs when a strong downdraft reaches the surface. To visualize this process, imagine the way water comes out of a faucet and hits the bottom of a sink.

2024年6月22日 · Learn about a microburst and macroburst and the similarities and differences between downbursts and tornadoes.

2015年4月26日 · Conversely, downbursts that span greater than 2.5 miles in radius are called macrobursts. Macrobursts can last nearly half an hour and produce wind speeds in excess of 130 mph. According to NOAA,...

A macroburst is more than 4 km (2.5 miles) in diameter and can produce winds as high as 60 metres per second, or 215 km per hour (200 feet per second, or 135 miles per hour). A microburst… Read More

2024年8月8日 · A macroburst is a burst of wind that causes damage extending more than 2 1/2 miles and lasting for at least 5 to 20 minutes.

Macroburst A convective downdraft with an affected outflow area of at least 2½ miles wide and peak winds lasting between 5 and 20 minutes. Intense macrobursts may cause tornado-force damage of up to F3 intensity.

2023年4月17日 · One of 2 categories of downbursts (the other category is called a macroburst). This downburst has an affected outflow area of less than 2.5 miles (4 kilometers) wide and peak winds lasting less than 5 minutes.

In meteorology, a downburst is a strong downward and outward gushing wind system that emanates from a point source above and blows radially, that is, in straight lines in all directions from the area of impact at surface level. It originates under deep, moist convective conditions like cumulus congestus or cumulonimbus.

2017年4月13日 · Macrobursts have damaging winds that extend more than two and half miles and can be as high as 134 mph, often causing widespread, tornado-like damage in the process. They last five to 30 minutes....

Discover the key difference between a microburst and macroburst. Learn about these weather phenomena and how they can cause significant damage, as well as what safety measures you should take in case of severe weather.
