Please visit the NOAA's Radar Operations Center for more information. The Interactive Radar Map Tool shows map layers at the maximum distance (230 km), as well as maps derived from geospatial models that provide views of areas blocked by mountains. However, mountains can block the lower sweeps of the radar beam. The typical range of most radar products is 230 km from the radar site. The map tool includes layers at 4,000 feet (best coverage), 6,000 feet (better coverage), and 10,000 feet (fair coverage).
Bright reflectivity returns that are stationary and appear during both calm and inclement weather are usually land-based obstructions such as mountains, trees, or especially wind farms (nothing gets electromagnetic signals confused like spinning metal blades!).The analysis conducted by NOAA's Radar Operations Center shows the availability of beam coverage at specified altitudes from the ground. These maps consist of echo top heights, cell movement indicators, tornado and severe thunderstorm. This is helpful for picking out snow/mix/rain transition zones In all snow situations, dBZ values of 40 indicate 3-4”/hr snowfall rates and whiteout conditions. The NOWRAD Radar Summary maps are meant to help you track storms more quickly and accurately. Anything larger than this is usually due to “bright banding” where the radar is seeing the part of the atmosphere where snowflakes are clumping together and melting into raindrops. In cold climates during the winter months, actual dBZ values rarely exceed 40. This is your standard radar data that shows precip or other solid/liquid particles in the atmosphere. The first type of data currently available is reflectivity. We currently have two types of radar data available with plans to add more soon. Use radar data with caution especially if your area of interest is far from the nearest radar location! A lot can happen between 0 and 5,000 feet and therefore the depiction of precipitation given by radar may differ some from what’s actually happening on the ground. Because of this phenomenon, the radar beam will only see precipitation falling through the mid levels of the atmosphere. To see this in action, imagine a circle (earth) with a straight line emanating from some point on the circle if you continue this line out into space, it will gradually get farther and farther from the circle. Because the earth is round and the radar beam is flat, the farther away from the radar tower the beam (energy) travels, the farther removed from the ground becomes. There is a notable constraint to radar data though. This is the highest resolution radar data available which enables you to see features such as sea breeze or outflow boundaries that standard resolution radar entirely misses. This data is gathered from over a hundred radar towers located across the US. Lake Murray, Ardmore OK (WeatherOK, USA). Past us doppler radar plus#
Lightning CG worldwide (since 2004) Plus Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion.
