Question

If the Doppler radar is measuring an echo of 41 dBZ, what is the corresponding rainfall rate?

Answer 1

Answer:

R = 0.52 in/h

Explanation:

The rainfall rate (R) can be calculated using the Marshall-Palmer equation:

$R = (\frac{10^{\frac{dBZ}{10}}}{200})^{\frac{5}{8}}$                         (1)

The dBZ given is equal to 41, so introducing this valor into the equation (1) we can find the rainfall rate:

$R = (\frac{10^{\frac{41}{10}}}{200})^{\frac{5}{8}} = 13.32 mm/h = 0.52 in/h$    

Therefore, the rainfall rate corresponding to an echo of 41 dBZ is 0.52 in/h.

I hope it helps you!  

Answer 2

Answer:R = 0.52 in/h

Explanation:

The rainfall rate (R) can be calculated using the Marshall-Palmer equation:

                        (1)

The dBZ given is equal to 41, so introducing this valor into the equation (1) we can find the rainfall rate:

   

Therefore, the rainfall rate corresponding to an echo of 41 dBZ is 0.52 in/h
