For reference

A microburst is a convective downdraft with an affected outflow area of less than 2 1/2 miles wide and peak winds lasting less than 5 minutes. Microbursts may induce dangerous horizontal and vertical wind shears, which can adversely affect aircraft performance and cause property damage. Straight-line winds are generally any wind that is not associated with rotation, used mainly to differentiate them from tornadic winds.

Radar Data and Loops

The image below is a four panel display showing base reflectivity at four different elevations, 0.5, 1.5, 2.4, and 3.4 degrees.

Hail spike on radar.

The white arrows shows a feature called three-body scatter spike (TBSS), or hail spike, and is an indication that large hail is contained in the thunderstorm. However, the TBSS signature itself is not real, i.e., it is not raining where the spike is. Instead, it is an erroneous return of weak energy back to the radar after the original beam of energy from the radar hits the large hail in the storm. reference.
