Mobile doppler weather radars have been used on dozens of scientific and academic research projects from their invention in the late 1900s. [1] One problems facing meteorological researchers was the fact that mesonets and other ground-based observation methods were being deployed too slow in order to accurately measure and study high-impact atmospheric phenomena.

A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered
where , is the amplitude of the electric field scattered by the mth scatterer, is the position of the mth scatterer, is the carrier frequency and , represents the shift in phase of the scattered wave in the direction of the radar due to the relative radial velocity of the target with respect to the radar, while , and are respectively the phase ...
The first weather satellite to be considered a success was TIROS-1, launched by NASA on April 1, 1960. [5] TIROS operated for 78 days and proved to be much more successful than Vanguard 2. Other early weather satellite programs include the 1962 Defense Satellite Applications Program (DSAP) [6] and the 1964 Soviet Meteor series.
The cone represents the probable position of a tropical cyclone's circulation center, and is made by drawing a set of circles centered at each forecast point—12, 24, 36, 48, and 72 hours for a three-day forecast, as well as 96 and 120 hours for a five-day forecast. The radius of each circle is equal to encompass two-thirds of the historical ...
