The multiple reflections of the radar beam causing the hail spike. Generally known as hail spikes, these are the result of energy from the radar hitting hail, very heavy rain, or in extreme cases, debris being lofted by a tornado, and being reflected to the ground, where they reflect back to the hail and then to the radar as in the image on the left.

The frequency selection of weather radar is a performance compromise between precipitation reflectivity and attenuation due to atmospheric water vapor. Some weather radars uses doppler shift to measure wind speeds and dual-polarization for identification of types of precipitations. [3] [4] Weather radar; Wind profilers; Millimetre cloud radar ...
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
The group’s mission is to “develop a fully 3D weather radar that can accurately track the movement and growth process of cloud particles and large-scale weather fronts.”“Detecting small ...
According to the National Weather Service, an arctic airmass “should bring daytime highs down to as much as 15 to 20 degrees below normal” for parts of the Northeast and the Mid-Atlantic on ...
A NEXRAD weather radar currently used by the National Weather Service (NWS) is a 10 cm wavelength (2700-3000 MHz) radar capable of a complete scan every 4.5 to 10 minutes, depending on the number of angles scanned, and depending on whether or not MESO-SAILS [7] is active, which adds a supplemental low-level scan while completing a volume scan ...
MyRadar is a free weather forecasting application developed by Andy Green and his Orlando, Florida-based company ACME AtronOmatic (ACME). The app began operations in 2008 and ran on government-provided weather and radar data for its first decade. In 2019, ACME launched personal satellites to improve predictions of ongoing weather.
DOW data revealed some of the most intense tornadic winds ever recorded (the Bridge Creek–Moore tornado, 3 May 1999, the El Reno tornado, 31 May 2013, and the Greenfield, Iowa Tornado, 21 May 2024), [16] [17] and the largest tornadic circulation ever documented (the Cimarron City–Mulhall–Perry Tornado, which also occurred on 3 May, 1999 ...
