Weather - seek Exampleere tornadoes, so as to give them a considerable amount of time to gather their family and primary(prenominal) documents/collectables and seek shelter at a safe and secure place.Radars are machinelike devices which tap 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 issue radio waves which then reflect off minor atmospheric particles such(prenominal) as rain trim downs, 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 base characteristics they may portray, such as location based precipitation (Lubchenco & Hayes, 2012).Currently the National Weather armed 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 doesnt tell meteorologists anything about the configuration 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 betwixt the types of participation found in particles and the its amount, something which the Doppler Radar majorly lacked at. Dual polarization, in very simple dustup 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,
