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.

Biden adds stop to North Carolina trip to visit with families of fallen law enforcement officers
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.
Biden to travel to North Carolina to meet with families of officers killed in deadly shooting
Four Charlotte-Mecklenburg Police Department officers were shot, one of whom died. Marshals Fugitive Task Force were also shot, three of whom died. Wilson described the scene as “gunfire galore,” with officers army-crawling through his backyard, hiding behind trees, and jumping around bushes. The North Carolina Department of Adult Corrections stated that two of the members of the task force were veterans of their department. They were identified as Sam Poloche and Aledn Elliot. Poloche leaves behind a wife and two children, and Elliot and his wife were parents to one child.
Official Statements
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 is a common question about many long-lived historical tornadoes, including the apparent US record 'Tri-State tornado' in March 1925, which was said to have a continuous path length of 219 miles." Once again, Biden will seek to be an empathetic leader for a community reeling from gun violence, while also calling for stricter rules around firearms and better funding for law enforcement on the front lines. These are most common in the fall around bodies of water that typically have temperatures warmer than the surrounding land at night. It is also the time birds are gathering for the seasonal migration. Just before sunrise, there is often a coordinated lift off and dispersion of the birds out into the surrounding fields for feeding during the day.
After his speech, Biden met with relatives of both of the officers’ families. Like the WSR-88D, the TDWR scan strategy is separated into either a clear air or precipitation mode. The TDWR clear air mode is referred to as "monitor mode" or VCP 90 and the precipitation mode is called "hazardous weather mode" or VCP 80. Update times will vary depending on the mode the radar is using. The lowest short-range scan of the "monitor mode" will update every 5.4 minutes. However, the lowest scan of the "hazardous weather mode" will generate every minute.
law enforcement officers killed, 4 injured trying to serve felony warrant
Back the Blue NC has started a GoFundMe to assist those affected by Monday’s deadly shooting and released this statement on the page. Hughes’ criminal record in North Carolina goes back more than a decade. It includes prison time and convictions for breaking and entering, reckless driving, eluding arrest and illegally possessing a gun as a former felon, according to state records. Three were killed during the incident, one of whom was confirmed to be a U.S. After a three-hour standoff, the suburban Charlotte home was torn open. Armored vehicles smashed into it, ripping off windows and entire doorways that were left broken.
Two people, a woman and a 17-year-old male, were taken to the police station as persons of interest. Police also say a high-powered rifle was seized from the home. Authorities said 12 Charlotte-Mecklenburg Police officers fired their service weapons and are on administrative leave while an investigation is underway.
The strongest tornado
Read our article to see how we are using Artificial Intelligence. Outside the Charlotte Mecklenburg Police Department's North Tryon Division on Wednesday, Eyer's patrol car was draped with an American flag and covered with flower bouquets from community members who stopped to pay their respects. Officers returned fire, killing one suspect who was later pronounced dead in the front yard of the home. When they arrived, they were met by gunfire, according to WBTV. Authorities said they are not looking into additional suspects or persons of interest. Lt. Gov. Mark Robinson also took to social media to address the shooting.
Sacramento County has dedicated teams of mental health counselors and specialists to routinely visit encampments and shelters to offer services. The effort cost roughly $2.7 million last year, according to data the county provided KCRA 3 Investigates. Law enforcement officers were still investigating Wednesday, attempting to determine a precise timeline of events and whether Hughes acted alone or with a second shooter. After the attack, Biden expressed his condolences and support for the community, calling the slain officers “heroes who made the ultimate sacrifice, rushing into harm’s way to protect us." Charlotte-Mecklenburg police said Monday night an officer who had been injured in the shooting had died.
More than 100 shell casings will be collected, according to Chief Johnny Jennings. At the scene, authorities recovered an AR-15 and 40-caliber handgun, along with additional magazines for both guns. Within two weeks of the April 16, 2011, outbreak, the days of April 27 and 28 saw 13 tornadoes.
Of all the storms, the tornado that touched down in Harnett County, which is located just south of Raleigh, tracked northeastward 160 miles to Elizabeth City. The F4 tornado with the longest track in North Carolina history was on the ground for 83 miles. The old Fujita scale didn’t estimate exact wind speeds like the modern scale. Instead of using wind speed to determine the strong tornado, let us use path length. North Carolina has had a dozen F4 tornadoes on record. All were before the enhanced scale began in 2007 and thus North Carolina has never had an EF4 tornado.
Submarines do, however, have radar systems they can use while they're moving abouton the ocean surface (such as when they're entering and leaving port). The ability to detect the "shift in the phase" of the pulse of energy makes NEXRAD a Doppler radar. The phase of the returning signal typically changes based upon the motion of the raindrops (or bugs, dust, etc.).
Live on WBTV, Tyler Wilson described officers streaming into his home, including one officer who appeared to be a sniper using his window during an active shootout Monday afternoon. At one point, Wilson said he saw one officer dragged through his home by his shoulders. He wasn’t able to see the extent of the officer’s injuries or whether the officer was shot. During a news conference Monday afternoon, Charlotte-Mecklenburg Police Chief Johnny Jennings said the U.S.
