Question

Examine the radar image below which shows storms that passed over central Wisconsin and answer the following questions P.com TH 1. Part of the storms in Wood County produced CLARK radar reflectivity echoes of 41 dBZ over the northern part of the county for 1 hour. How much rain did that location receive from these storms during that hour? PORTAGE 2. Was there any hail in these storms? Please explain how you arrived at your answer 3, what do meteorologists call the non- a meteorological radar echoes that the white arrow is pointing to?

Explanation / Answer

1. Given that the reflectivity is 41dbZ,

we know that the radar equation is

Rate= (10(dbZ/10)/200)5/8

= (1041/10)/200)5/8

= 62.945/8 = 13.31 mm/hr

2. Yes there is hail in this storm as the reflectivity in most parts is greater than 55. If hail were to be present, there should be a radar reflectivity greater than 55dbZ.

3. The non meteorological echoes are nown as noise
