Although many scientists contributed to the development of radar,best known among them was a Scottish physicist named Robert Watson-Watt(1892–1973). During World War I, Watson-Watt went to work for Britain'sMeteorological Office (the country's main weather forecastingorganization) to help them use radio waves to detect approaching storms. Radar can be traced back to a device called a Telemobiloskop(sometimes written French-style, Télémobiloscope), invented in 1904by German electrical engineer Christian Hülsmeyer (1881–1957). After hearingabout a tragic collision between two ships, he figured out a way to use radio waves to help themsee one another when the visibility was poor. As officers approached Hughes, they said they were met by more gunfire from inside the home.

This Doppler effect was named after the Austrian physicist, Christian Doppler, who discovered it. You have most likely experienced the "Doppler effect" around trains. We're finding out more about the man who investigators said opened fire on officers Monday afternoon in Charlotte before he was later shot and killed. We also extend our support to the officers’ families, loved ones, and teammates.
KCRA Today: Police arrest UCLA protesters, mountain lion kills family dog, CPR lesson put to use
– President Joe Biden is expected to travel to North Carolina on Thursday to meet with the family members of four officers killed earlier this week in the deadliest attack on U.S. law enforcement since 2016. "I am deeply saddened by the shooting that occurred that involved Charlotte-Mecklenburg police officers and US Marshals today," she said. "I ask that all Charlotteans keep them, the other injured officers, and their families in your thoughts and prayers during this incredibly difficult time." Velocity data is derived from the phase, or doppler shift of the returned energy. The radar's computers will calculate the shift and determine whether the precipitation is moving toward or away from the radar, and how fast, then apply a corresponding color to those directions and speeds.
Doppler radar is also used inweather forecasting to figure out how fast storms are moving and whenthey are likely to arrive in particular towns and cities. Effectively,the weather forecasters fire out radar beams into clouds and use thereflected beams to measure how quickly the rain istraveling and how fast it's falling. Scientists use a form of visibleradar called lidar (light detection andranging) to measure air pollution with lasers. Archeologists and geologists pointradar down into theground to study the composition of the Earth and find buried depositsof historical interest. The antenna doubles up as a radar receiveras well as a transmitter. In fact, it alternates between the two jobs.Typically it transmits radio waves for a few thousandths of a second,then it listens for the reflections for anything up to several secondsbefore transmitting again.
In an update Monday evening, Jennings said Officer Joshua Eyer with CMPD died from his injuries after being shot that afternoon. Over the last 30 years, North Carolina averaged 30 tornadoes per year with a majority happening east of Charlotte. Beginning with the legacy Fujita Scale from 1950 to 2006, F1s account for 41.3% of all of North Carolina's tornadoes. Combined, F0 and F1 tornadoes make up nearly 80% of all recorded tornadoes in the state. Among North Carolina's years with the most tornadoes, 2011 and 1998 are a close second. Almost half of the tornadoes in 2011 occurred on that single date, April 16.

President Biden to visit Charlotte to meet families of officers killed in Monday's shooting
While the antenna is transmitting, it cannot receive—andvice-versa. Take a look at the diagram in the box below to see how allthese parts of the radar system fit together. Protesters described chaos as police descended on the campus, where more than a dozen pro-Palestinian demonstrators were taken away in zip-tie handcuffs as supporters screamed in outrage.
Processional Held For Fallen Deputy U.S. Marshal Thomas Weeks, Jr.
Our Atrium Health Carolinas Medical Center emergency department teammates immediately began providing care to the injured. We have also been extending emotional support to their families and colleagues. Also on Wednesday, a local police chief said that an officer from his force who was shot Monday underwent surgery and is expected to make a full recovery. David W. Onley, the police chief of Statesville in the Charlotte metropolitan area, expressed condolences Wednesday and “unwavering solidarity with our law enforcement brethren during this difficult time,” according to a statement released by his office. We must do more to protect our law enforcement officers.

There are two main types of data, Velocity and Reflectivity. As a train passes your location, you may have noticed the pitch in the train's whistle changing from high to low.

Any reflected radio waves picked up by theantenna are directed into a piece of electronic equipmentthat processes and displays them in a meaningful form on a television-likescreen, watched all the time by a human operator. Thereceiving equipment filters out useless reflections from the ground,buildings, and so on, displaying only significant reflections on thescreen itself. Using radar, an operator can see any nearby ships orplanes, where they are, how quickly they're traveling, and wherethey're heading. Watching a radar screen is a bit like playing a videogame—except that the spots on the screen represent real airplanes andships and the slightest mistake could cost many people's lives. The attack was the deadliest day for U.S. law enforcement in one incident since five officers were killed by a sniper during a protest in Dallas in 2016.
Click on the image to the left for a quick animation of the bird rings. In the historic first criminal trial of an ex-president, Donald Trump faces 34 felony counts of falsifying business records to cover up a violation of campaign finance law. But despite such a major event, there are no video cameras allowed in the courtroom, and no still photos save for those typically taken of the defense table in a minute-long photo opportunity. Millions of Americans following cannot see what the trial actually looks like. If you were there, here's what you would feel and see. OVERLAND PARK, Kan. (KCTV) - A 15-year law enforcement veteran shot to death on Monday in North Carolina had ties to the Kansas City area.
The radar mode is indicated in the lower left-hand corner of the radar image, see Figure 4. Three US Marshals were killed and another was left injured after being shot while attempting to issue a warrant Monday afternoon in East Charlotte. One CMPD Officer was killed while three other officers were shot and injured by suspects within the home after arriving to assist the US Marshals. During the war, Britain'sradar defenses (known as Chain Home) gave it a huge advantage overtheGerman air force and played an important part in the ultimate alliedvictory.
Believe it or not, these past few days of pleasant 80-degree weather will tumble back into wet and cold weather for Northern California this weekend. Fifth body recovered from site of Baltimore bridge collapse, victim identified
We recognize our responsibility to use data and technology for good. NEXRAD spends the vast amount of time "listening" for returning signals it sent. When the time of all the pulses each hour are totaled (the time the radar is actually transmitting), the radar is "on" for about 7 seconds each hour. The remaining 59 minutes and 53 seconds are spent listening for any returned signals. We recognise our responsibility to use data and technology for good.
