Understanding Weather Radar Weather Underground

The radar reflectivity factor (Z) of precipitation is dependent on the number (N0) and size (D) of reflectors (hydrometeors), which includes rain, snow, graupel, and hail. Very sensitive radars can also measure the reflectivity of cloud drops and ice. For an exponential distribution of reflectors, Z is expressed by: As rain droplets have a diameter on the order of 1 millimetre, Z is in mm m (μm ). By dividing Z wi… WebDetection Conceptual Model Diagnosis References/Addendum Detection A 50 dBZ Echo Top signature refers to the height of the highest echo that is greater than 50 dBZ within a storm’s radar reflectivity core.
