Mkokomo wa microburst ndi wochepa kwambiri, wotsika kwambiri womwe umatsikira pansi chifukwa cha mphepo yamphamvu.
Kukula kwa chochitikacho ndikumachepera makilomita 4 kudutsa. Microbursts amatha kupanga mpweya wa mph 100 mph kuwonongeke kwambiri. Mpweya wa microburst uli pafupi 5-15 minutes. Pali microbursts zowonongeka ndi microbursts youma.
Mvula ikagwa pansi pa mtambo kapena yowumitsa mpweya wouma, imayamba kutuluka ndipo mpweyawu umatulutsa mpweya. Mpweya wozizira umatsika ndipo umayenda mofulumira pamene ukuyandikira pansi. Pamene mphepo yozizira imayandikira pansi, imafalikira kumbali zonse ndipo kusiyana kwa mphepo ndiko kusaina kwa microburst. M'nyengo yamvula, microbursts imatha kupanganso kuchokera mvula yamkuntho.
Microbursts ndizowonongeka mofulumira ndipo ndizoopsa kwambiri kuyendetsa ndege. Ma Microbursts amadziwika kuti ndi ouma kapena otentha, chifukwa cha kuchuluka kwa mvula yomwe imayendetsedwa ndi microburst ikafika pansi. Ngati nsombayi ili ndi makilomita oposa 2.5, imatchedwa macroburst.
