The number of scanned angles was increased to get a three-dimensional view of the precipitation, so that horizontal cross-sections ( CAPPI) and vertical cross-sections could be performed. The first devices to capture radar images were developed. Дuring the 1970s, radars began to be standardized and organized into networks. Just 46 people were killed thanks to the warning and it was estimated that the evacuation saved several thousand lives, as the smaller 1900 Galveston hurricane had killed an estimated 6000-12000 people. This made Rather a national name and his report helped in the alerted population accepting the evacuation of an estimated 350,000 people by the authorities, which was the largest evacuation in US history at that time. During the broadcast, he held that transparent overlay over the computer's black-and-white radar display to give his audience a sense both of Carla's size and of the location of the storm's eye. He convinced the bureau staff to let him broadcast live from their office and asked a meteorologist to draw him a rough outline of the Gulf of Mexico on a transparent sheet of plastic. Weather Bureau WSR-57 radar site in Galveston in order to get an idea of the size of the storm. As Hurricane Carla was approaching the state of Texas, local reporter Dan Rather, suspecting the hurricane was very large, took a trip to the U.S. The first use of weather radar on television in the United States was in September 1961. In 1953 Donald Staggs, an electrical engineer working for the Illinois State Water Survey, made the first recorded radar observation of a ' hook echo' associated with a tornadic thunderstorm. The early meteorologists had to watch a cathode ray tube.

ДЎ960s radar technology detected tornado producing supercells over the Minneapolis-Saint Paul metropolitan area.Д«etween 19, reflectivity radars, which measure position and intensity of precipitation, were incorporated by weather services around the world. By 1950 the UK company EKCO was demonstrating its airborne 'cloud and collision warning search radar equipment'. In the United Kingdom, research continued to study the radar echo patterns and weather elements such as stratiform rain and convective clouds, and experiments were done to evaluate the potential of different wavelengths from 1 to 10 centimeters. Marshall and his doctoral student Walter Palmer are well known for their work on the drop size distribution in mid-latitude rain that led to understanding of the Z-R relation, which correlates a given radar reflectivity with the rate at which rainwater is falling. Douglas formed the 'Stormy Weather Group' in Montreal. In the United States, David Atlas at first working for the Air Force and later for MIT, developed the first operational weather radars. After the war, military scientists returned to civilian life or continued in the Armed Forces and pursued their work in developing a use for those echoes. Typhoon Cobra as seen on a ship's radar screen in December 1944.Дuring 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 used and specialized software can take radar data to make short term forecasts of future positions and intensities of rain, snow, hail, and other weather phenomena. Since then, weather radar has evolved on its own and is now 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.Дuring World War II, radar operators discovered that weather was causing echoes on their screen, 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.).
