Radar Measurement of Rainfall Solution

STEP 0: Pre-Calculation Summary

Formula Used

Average Echo Power = (A constant*Radar-Echo Factor)/Distance to Target Volume^2
P_r = (C_radar*Z)/r^2
This formula uses 4 Variables

Variables Used

Average Echo Power - Average Echo Power is the range at which the radar echo signal S received from a target exceeds the received jamming when raindrops intercept a radar beam.
A constant - A constant generally used in the radar measurement of rainfall.
Radar-Echo Factor - Radar-Echo Factor when raindrops intercept a radar beam. It is generally related to intensity of rainfall.
Distance to Target Volume - (Measured in Meter) - Distance to Target Volume when raindrops intercept a radar beam.

STEP 1: Convert Input(s) to Base Unit

A constant: 2 --> No Conversion Required
Radar-Echo Factor: 424.25 --> No Conversion Required
Distance to Target Volume: 20000 Millimeter --> 20 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_r = (C_radar*Z)/r^2 --> (2*424.25)/20^2

Evaluating ... ...

P_r = 2.12125

STEP 3: Convert Result to Output's Unit

2.12125 --> No Conversion Required

FINAL ANSWER

2.12125 <-- Average Echo Power

Radar Measurement of Rainfall

Go Average Echo Power = (A constant*Radar-Echo Factor)/Distance to Target Volume^2

Intensity of Rainfall given Radar Echo Factor

Go Intensity of Rainfall = (Radar-Echo Factor/200)^(1/1.6)

Radar Echo Factor using Intensity

Go Radar-Echo Factor = 200*Intensity of Rainfall^1.6

Radar Measurement of Rainfall Formula

Average Echo Power = (A constant*Radar-Echo Factor)/Distance to Target Volume^2
P_r = (C_radar*Z)/r^2

What is Radar Measurement of Rainfall?

Radar provides an alternative means of measuring rainfall over an area. Radars designed specifically to detect precipitation are being used increasingly by meteorological services throughout the world.

What is Rainfall Intensity?

Rainfall intensity is defined as the ratio of the total amount of rain (rainfall depth) falling during a given period to the duration of the period It is expressed in depth units per unit time, usually as mm per hour (mm/h).

How to Calculate Radar Measurement of Rainfall?

Radar Measurement of Rainfall calculator uses Average Echo Power = (A constant*Radar-Echo Factor)/Distance to Target Volume^2 to calculate the Average Echo Power, The Radar Measurement of Rainfall formula is defined as the meteorological radar, a powerful instrument for measuring the areal extent, location and movement of storms. Constant is where the raindrops intercept a radar beam. Average Echo Power is denoted by P_r symbol.
