1. Identifying tornadoes using Doppler radar
Elaina Cooley
EECS 622: Final Project

2. What I need to know
Gradient Doppler velocities are used to find the vortex signature of a tornado
Beam Width
Resolution volume size – Can’t be too large or too small. Has to be “Just right”
Reflectivity of hydrometeors
Drop size distribution
Wind velocity

3. Thunderstorm structure

4. Thunderstorm structure

5. Rainfall Rates
Measured drop size distributions for various rain fall rates

6. Wind velocity Can’t see air Volume Backscattering – Rain
Scattering Models
Linear wind velocity model
