.I have seen tornado damage up close and personal. This attenuation means that the radar cannot "see" very far through heavy rain.
Typically, light rain is occurring when the dBZ value reaches 20. Extra detail can also been seen at long-ranges, and the TDWRs should give us more detailed depictions of a hurricane's spiral bands as it approaches the coast.The VAD Wind Profile image presents snapshots of the horizontal winds blowing at different altitudes above the radar. When I was in the Army, stationed in Oklahoma, we staffed our own ambulances. This product is used to locate flood potential over urban or rural areas, estimate total basin runoff and provide rainfall accumulations for the duration of the event.The Storm Attributes Table is a NEXRAD derived product which attempts to identify storm cells.The Terminal Doppler Weather Radar (TDWR) is an advanced technology weather radar deployed near 45 of the larger airports in the U.S.
I am terrified and have been having nightmares now that tornado season is here.
A lot of what you will see in clear air mode will be airborne dust and particulate matter. We have our BOBs in the same closet. Green is rain.
Watched a tv reporter showing damage done by a tornado with a guy walking through the debris wearing flip flops. I was moving like a robot being told what to do. This image will not show echoes that are more distant than 143 miles, even though precipitation may be occurring at these greater distances. The radars were developed and deployed by the Federal Aviation Administration (FAA) beginning in 1994, as a response to several disastrous jetliner crashes in the 1970s and 1980s caused by strong thunderstorm winds. Since the radar is geared towards examining the weather in high detail at short range, echoes that come back from features that lie at longer ranges suffer from what is called range folding and aliasing. Pretty close.Where I used to live an F1 hit 1/4 of a mile from me. But it was touch and go for a couple of hours. The radar's computers measure the frequency change of the reflected pulse of energy and then convert that change to a velocity of the object, either toward or from the radar. All I hear when I ask these questions is jokes horror stories and immaturity when the answers I need could save our lives!Tornado Alley, Tornado Facts, and How They Form
A “hook echo” describes a pattern in radar reflectivity images that looks like a hook extending from the radar echo, usually in the right-rear part of the storm (relative to the motion of the storm). The cost would far outweigh the production gained , plus it says to your employees ” you really don’t matter as much as production , In one instance the employees started a petition and submitted it to the company after refusal to let them seek shelter , which resulted in a written reprimand to the supervisor. Near Bradenton had a tornado warning even a alert on my phone tonight. Whoa what tha heck. We had shattered glass. Ten minutes later and the whole town was gone. 90% of the time, the mesocyclone (and tornado) will be spinning counter-clockwise.The National Weather Service's 148 WSR-88D Doppler radars can detect most precipitation within approximately 90 mi of the radar, and intense rain or snow within approximately 155 mi. Plus a loss of faith in them from the employees .
An mathematical algorithm can be applied to the radar data to remove echoes where the echo intensity changes rapidly in an unrealistic fashion. (and it was tied down.!
Image 1 Image 2: Blue shows where snow is most likely. They are just too personal a disaster! It took a church that was on our street. Yeah, the big tree blocking the road was annoying. Snow that is melting aloft will also often show as yellow or orange since radar thinks it is small hail.
One of the problems I have seen is so many warnings are issued on TV, radio, and on cellular that people tune them out. Purple to white colors can indicate hail. This increased sampling increases the radar's sensitivity and ability to detect smaller objects in the atmosphere than in precipitation mode. This "ground clutter" generally appears within a radius of 25 miles of the radar as a roughly circular region with a random pattern.
The higher the dBZ, the stronger the rainrate.
