[INTRO] 2. Size, type and effects of downbursts / [ADVANCED] X.1 nova stran

Depending on the area they affect, downbursts are divided into two categories:

  • MICROBURST: is a downburst affecting an area 4 km in diameter or less. Microbursts typically last 5 to 15 minutes. The strongest winds can exceed 180 km/h.
  • MACROBURST: is a downburst affecting an area more than 4 km in diameter.
