History Typhoon Cobra as seen on a ship's radar screen in December 1944.ĭuring World War II, military radar operators noticed noise in returned echoes due to rain, snow, and sleet. Radar output is even incorporated into numerical weather prediction models to improve analyses and forecasts.

Raw images are routinely processed by specialized software to make short term forecasts of future positions and intensities of rain, snow, hail, and other weather phenomena. Since then, weather radar has evolved and is used by national weather services, research departments in universities, and in television stations' weather departments. Soon after the war, surplus radars were used to detect precipitation.

Techniques were developed to filter them, but scientists began to study the phenomenon. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather.ĭuring World War II, radar operators discovered that weather was causing echoes on their screens, masking potential enemy targets. Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation. 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.).

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).
