Radars are mechanical devices which work by sending and receiving signals which are further used to analyze weather conditions. Coming to the technical side of the issue, radars work by sending out radio waves which then reflect off minor atmospheric particles such as raindrops, ice and dust amongst others. When the waves sent off to these particles come back or return to the mechanical device, the data is used to measure the strength and time period of these waves to determine whatever weather based characteristics they may portray, such as location based precipitation (Lubchenco & Hayes, 2012). Currently the National Weather Service is using a Doppler based radar. This radar is also capable of measuring the frequency of the waves, which can be decoded to information about the velocity and direction at which precipitation in the atmosphere is moving. Even though the Doppler Radar is a sophisticated device that is used by many weather forecasters all over the globe, the device is far from perfect. The major setback associated with the Doppler Radar is the fact that it doesn’t tell meteorologists anything about the shape of the particle from which the waves retract, which leaves them open to guesswork to determine whether such a particle was a rain drop or a piece of snowfall, therefore making them unable to make detailed analysis out of the information that comes out of it. Dual polarization enables forecasters to differentiate with a significant amount of confidence between the types of participation found in particles and the it’s amount, something which the Doppler Radar majorly lacked at. Dual polarization, in very simple words enables forecasters to comprehend weather the particle that a radio wave retracted back from to the Radar was a rain drop or a dust particle (Lubchenco & Hayes,
