The Doppler spectrum is fundamentally concerned with the distribution of radial velocity as a function of power. It describes how the velocities of scatterers, such as precipitation particles or other objects in the atmosphere, are distributed over a range of speeds. When radar sends out pulses and then measures the frequencies of the returned signals, it can detect how the frequency has shifted due to the movement of these scatterers towards or away from the radar. This frequency shift is integral to determining radial velocity, allowing meteorologists to assess wind patterns, storm dynamics, and other critical atmospheric phenomena.

Understanding the Doppler spectrum is essential for weather radar applications, as it provides insights into the motion of objects within the radar beam, which is vital for accurate weather forecasting and severe weather detection. The clarity of this distribution allows meteorologists to analyze how fast and in what direction the precipitation is moving, which is crucial for predicting storm behavior.
