? Weather surveillance radar-57 – Definition and Explanations


National Weather Service antenna WSR-57

the WSR-57 (Wweather Sobservation RMarch 1957) was the primary weather radar in use in the United States beginning in 1957 and lasting 35 years. This was the first radar (Radar is a system that uses radio waves to detect and identify…) modern America to be placed network (A computer network is a set of devices connected to each other to exchange information…) to talk National Weather Service (The National Weather Service (NWS) is the weather service of the United States…). It has since been replaced by the radars of the NEXRAD network.

The story

After a tornado (Tornado (derived from the Spanish tornado, tornar, the verb to turn) is a whirlwind…) On May 11, 1953, in Waco, Texas, an F5 on the Fujita scale, the Weather Bureau (now NWS) convened a conference to discuss severe thunderstorm weather warnings. The results were better communications, a network of local observers and the creation of a network of radars. remote sensing (Remote sensing, broadly speaking, means measuring or acquiring…) storms.

At that time, the meteorological service had a number number (The concept of number in linguistics is considered in the article “Number…”) Military radars (APS-2) from surplus aircraft of the US Navy. These radars were their remnants Second (The second is the feminine of the second adjective immediately following the first, or which…) World war and only gave data (In information technology (IT), data is an elementary description, often…) at a low resolution poorly adapted to the detection of severe thunderstorms. The rains were also to be noted hand (The handshake effect is organ…) with a grease pen, then changed the angle of the synoptic antenna by hand request (Voiceover can determine the technique of local exploration of a certain environment. A…) at a higher level in the storm. The work required great experience, and it was quite difficult to judge the intensity of the “green spots” on a cathode-ray screen. Since they are in the S band (10 cm length (The length of an object is the distance between its two farthest ends…) wave), which was not attenuated by them, was suitable for the detection of heavy precipitation rain (Rain generally refers to water falling in a state…)but upgrading was likely to be expensive and time-consuming, so the Air Bureau was running out of funds.

The first operational prototype was built for the National Hurricane Center in Miami. It was later deployed in the contiguous United States. Its designation in military bases was AN/FPS-41.

By 1974, the WSR-57s were getting pretty old, and filler parts were no longer even being made in the US. The WSR-74S model began to replace them. They were similar radars, but a technology (The word technology has two de facto meanings 🙂 newer and more reliable. In 1990, when the new WSR-88D radars from the NEXRAD network began to take over, there were 128 radars of both models operating in the United States. In 1992, Hurricane Andrew blew out the WSR-57’s antenna. the roof (A roof is a structure that covers the top of a building, allowing…) From the National Hurricane Center. A recent image captured by this radar and neighboring WSR-88D radars can be seen in the hurricane report. The last WSR-57 was closed on December 2, 1996.
