Advancements of Local Weather Radar

 
 

Meteorologists have always felt responsible for reducing the number of lives lost at the hands of severe weather. Over the years, they have teamed up with some of the best scientists in the field to improve the accuracy and prediction of severe weather reports. Meteorologists think that residents need much more than the previously typical five minute warning in order to gather their loved ones and seek shelter. Advancements of local weather radar have given them a much clearer picture on what path a storm will take, allowing them to warn residents in the area as soon as possible.

Meteorologists and scientists have been able to successfully track severe thunderstorms and possible tornadoes by using an advanced tracking system called NEXRAD (Next-Generation Radar). NEXRAD is a tracking network made up of 158 Doppler weather radars. This high-resolution computerized system takes readings on the amount of precipitation in the air, the movements in the clouds, and the wind speeds during a storm. These readings are bounced back to a local weather computer, and a colorful image is rendered on the screen, giving meteorologists a clear picture of what kind of weather is on the horizon. This final image is what you see when the meteorologist breaks in with severe weather reports and warnings, usually with a description of how he maps weather radar.

In the case of severe weather, the meteorologist will relay the readings found by the local weather radar to the residents in the area. Most likely, on your television screen you will see a computer animated image of the approaching storm. If the storm is severe enough, then the National Weather Service (NWS) will issue severe weather reports of severe thunderstorm warnings for your area. In that case, the storm captured on radar will have produced strong readable winds, detectable lightening, and some hail. Paying attention to the weather map is vital when severe weather is around. On the television screen you will see several colors on the precipitation map, ranging from blue (the lightest) to black (the heaviest). If the colors for your specific area are yellow, take caution. If the colors range between orange and red, take cover immediately, as damaging winds and dangerous lightening have been reported.

Before a tornado struck Atlanta, Georgia in 2008, local meteorologists warned residents of severe weather. Local weather radar had picked up on destructive winds inside the storm, and the National Weather Service issued a severe tornado emergency when reports came in of large hail, increasing wind speeds, and wind rotation within the storm. One resident recalls: "I have never seen a storm so strong that the radar showed the color as being black!" Meteorologists were able to use the data to offer a predicted storm path, giving residents enough time to take cover. Paying attention to your local meteorologists, and not underestimating the accuracy of severe weather reports, is vital to your safety.
